Current refinance guidelines, updated from one source.
The block below holds the figures that frame a refinance file, read from Lendmire’s guideline sources and refreshed on this page when the agencies, HUD, VA, or the wholesale overlays change: the conventional leverage and the mortgage-insurance line, the streamline rules for an existing FHA loan, the IRRRL fee and seasoning for an existing VA loan, and the credit and ratio figures. The ladder underneath lists every route.
One-unit principal residence; mortgage insurance above 80%
The conventional rate-and-term refinance reaches 95% loan-to-value on the home the borrower lives in, with 97% only on the first-time-buyer programs for an agency-owned loan. It rolls in the old balance, the costs, and a purchase-money second; paying a non-purchase-money second or a credit line through it makes it a cash-out. Mortgage insurance begins above 80%; the owner may cancel it at 80% of the original value, and it falls away by itself at 78%.
An existing FHA loan, refinanced with a net tangible benefit and a limited credit review
The streamline is the lightest refinance FHA offers: no appraisal, a limited credit review, and a requirement that the new loan deliver a net tangible benefit, tested against the loan being replaced and its payment history. The premium continues. Where an appraisal is used, FHA’s rate-and-term reaches 97.75% on an owner-occupied principal residence.
An existing VA loan, no VA appraisal; seasoning of 210 days and six payments
An existing VA loan can be refinanced to a lower rate or from an adjustable to a fixed rate through the IRRRL: a 0.5% funding fee that can be financed and that exempt veterans do not pay, no appraisal required by VA, a net tangible benefit, and seasoning of 210 days and six payments on the loan being replaced. The home may be a primary, second, or investment property where the veteran previously occupied it.
DTI to 50%; jumbo from 660 on its lanes
Score and ratio for a Castle Rock refinance: 620 is the conventional floor, 50% the automated ratio ceiling, and the finding weighs the rest of the file. The jumbo lanes, for balances above the conforming limit, start at 660, reach 90% of value on the headline lane, lend to $5,000,000, and hold the ratio to 50% on the fixed lanes with reserves per the lane.
| Program | Loan being replaced / occupancy | Maximum LTV | Conditions |
|---|---|---|---|
| Conventional rate-and-term (Fannie Mae / Freddie Mac) | One-unit principal residence | 95% | limited cash-out: the old loan, the closing costs and a purchase-money second roll in, incidental cash only; 97% where the existing loan is agency-owned and the first-time-buyer program allows; mortgage insurance above 80% |
| FHA streamline | Existing FHA-insured loan | No LTV test | appraisal not required; net tangible benefit; limited credit review; the previous loan’s seasoning and payment history apply; FHA mortgage insurance continues |
| FHA rate-and-term | Principal residence (owner-occupied the previous twelve months) | 97.75% | with an appraisal and full credit review; FHA mortgage insurance on the new loan |
| VA IRRRL | Existing VA loan; a home the veteran previously occupied | No LTV test | 0.5% funding fee (financeable; exempt veterans pay none); no VA appraisal; net tangible benefit; seasoning the later of 210 days and six payments |
| Jumbo rate-and-term (wholesale lanes) | Above the conforming limit | 90% | 660+ score on the headline lane, loans to $5,000,000, DTI to 50% on the fixed lanes; reserves and the appraisal count per the lane |
A refinance that returns cash is a cash-out refinance and is covered by the conventional, FHA, VA and jumbo cash-out programs; a line of credit that leaves the first mortgage in place is the HELOC program. Each carries its own leverage and its own rules.

What a rate-and-term refinance is — and how the file is qualified.
A rate-and-term refinance is simple to describe and particular in its rules. The four cards below cover what the new loan is and what it may pay off, which of the four programs applies to the loan being replaced, how the benefit test and the break-even decide whether the refinance pays, and what to do when the real goal is cash rather than terms.
For the program overview, see Lendmire’s refinance program, or the statewide guide at Refinance in Colorado; when the goal is cash, see the cash-out refinance program.
One new loan replaces the old one
Replacing a mortgage means paying it off with a new one on the same home. The new balance is the old balance plus the closing costs, where they are rolled in, and nothing comes back to the borrower beyond an incidental amount; paying off a line of credit or a non-purchase-money second through the loan turns it into a cash-out, which is a different program with its own leverage.
Four programs, one question: which applies
Conventional is the general route: any first mortgage on a home the borrower lives in, tested against the value and the credit profile, with mortgage insurance above the published line and none below it. The FHA streamline and the VA IRRRL are reserved for loans already insured or backed by those agencies and trade an appraisal and a full review for a benefit test. Jumbo applies above the conforming limit.
The benefit test and the break-even
A refinance pays when the owner keeps the loan past the break-even and the term reset does not give back the saving in interest. On an FHA streamline or a VA IRRRL the new loan must also deliver a net tangible benefit as the agency defines it, and VA requires the fees and costs to be recouped within its window when the new loan does not exceed the payoff. The Castle Rock calculator below runs all three figures.
When the goal is cash, not terms
A rate-and-term refinance returns no cash. A Castle Rock owner who wants money at closing, to consolidate debt, renovate, or buy another property, wants a cash-out refinance, which is a different program with its own leverage, seasoning, and cost, and is covered by the conventional, FHA, VA, and jumbo cash-out guides on this site; a home equity line that leaves the first mortgage in place is the third option.
Nothing in the formula is a quote. The new rate is a published weekly benchmark you can overwrite, the costs are your estimate, and the result is the shape of a Castle Rock refinance, not its terms: the loan, the payment, the saving, the break-even, and the interest comparison, which a loan officer then prices in writing.
Where Castle Rock’s mortgages were written — and what a refinance changes.
Scale, not quotation: the median value says what a typical Castle Rock balance sits under, the ownership rate says how many mortgages the market holds, and the median income sizes the ratio a typical payment leaves. The program figures above do not move with any of them.
Read the figures as backdrop. A value well above the balance makes the appraisal a formality and the mortgage-insurance line easy to clear; a value close to the balance makes both decisive. The market sets the cushion, the program sets the cap.

Distinct Castle Rock neighborhoods, distinct refinance questions.
The Castle Rock submarkets below show where the mortgages sit and what a refinance there asks: the program the existing loan points to, the value the cap is tested against, and the costs the saving has to recover.
Homes paid off, or close to it
Paid-off homes are common in Castle Rock, and the refinance question for them is not this page’s question. With no loan to replace, the instruments are the cash-out refinance and the home equity line, each with its own guide and its own leverage. A rate-and-term refinance needs a loan to rewrite. Roughly 22,227 Castle Rock households own their homes on the latest Census estimate — 79% of all households, the pool a refinance draws on.
Thin comparable sales
In a smaller market like Castle Rock the appraiser works from fewer sales, and the value on a conventional refinance can come in below the owner’s expectation. It matters only when the loan sits near the cap or the insurance line; a long-held home with a small balance is unaffected. The FHA streamline and the VA IRRRL skip the appraisal, which is part of their appeal here. Median household income in Castle Rock sits near $145,197 on the latest Census estimate.
Manufactured and unusual homes
Manufactured homes and unusual properties around Castle Rock refinance when the program accepts the property: the conventional, FHA, and VA routes each carry their own conditions for a manufactured home, the foundation and the title among them, and the loan officer confirms eligibility before the value is discussed. The streamlines apply to the existing government loan on an eligible property. Castle Rock is home to about 79K people.
Fixing a rate, shortening a term
In a market of high home values and long tenure, the refinance that pays is usually the shorter term, which cuts the interest on a loan the owner has carried for a decade, or the fixed rate, which ends the resets on an adjustable loan. A lower payment on a small remaining balance rarely recovers its costs, and the Castle Rock review says as much. The median owner-occupied home value in Castle Rock runs near $652,900 on the latest Census estimate.
Rentals and duplexes
The small-rental refinance in Castle Rock is the ordinary file with the occupancy’s own leverage and the lease in the documents. The IRRRL serves a veteran’s former home now rented; the conventional route serves the rest; cash out of a rental is a different program with its own guide. On a Castle Rock home at the median value, a conventional rate-and-term refinance at the leverage cap allows a new loan up to $620,000 — the existing loan, the closing costs, and a purchase-money second lien are what it may pay off.
Older homes with long tenure
On a small balance the monthly saving from a refinance is small too, and the closing costs can take years to recover; a Castle Rock owner with a modest loan should read the break-even before anything else. Where the refinance pays, it is usually by shortening the term or fixing a rate, not by lowering a payment that is already low. About 21% of Castle Rock’s households rent — roughly 5,992 renter households on the latest Census estimate.
Neighborhood moves the appraisal and the equity cushion; the program stays put. Wherever in Castle Rock the home sits, the leverage, the mortgage-insurance line, the streamline and IRRRL conditions, and the credit figures are the ones in the snapshot.
Four reasons Castle Rock homeowners rewrite the mortgage.
A mortgage is refinanced for a reason, and the reason picks the program and the term. These are four of the reasons that bring Castle Rock homeowners to a rate-and-term refinance most often, with what each one asks of the file.
Remove or add a borrower
A name comes off the note only when the loan is rewritten, and the remaining borrower qualifies alone on income, credit, and the ratio. The Castle Rock file is otherwise an ordinary rate-and-term refinance, with the decree, the deed, or the estate documents added; where equity is paid to the departing owner through the loan, the cash-out rules apply instead.
Fold in a purchase-money second lien
Two loans into one is a rate-and-term refinance when the second was part of the purchase. The payoff of both, plus the costs, becomes the new balance and is tested against the cap; the file is otherwise ordinary. A Castle Rock owner whose second lien was opened after the purchase, or who drew on a line later, is reading the cash-out guide, not this one.
Get rid of mortgage insurance
An FHA borrower whose home has gained value can refinance into a conventional loan at or below the no-insurance line and leave the premium behind for good; a conventional borrower paying private mortgage insurance can do the same, or can ask the servicer to cancel it at the published line without refinancing at all. The appraisal sets the value, and the value decides which route is open.
Lower the monthly payment
A lower payment comes from a lower rate, a longer term, or both. The first is a saving; the second is a loan stretched across more years, which can cost more in interest even as the payment falls. The break-even on the costs and the interest comparison over the two terms are the figures that separate a refinance that pays from one that only feels like it does.
Estimate the new payment and the break-even on a Castle Rock home before requesting a quote.
The calculator does the refinance arithmetic for a Castle Rock home: current payment from the balance, the current rate and the years remaining; new payment from the new loan, the new term and the benchmark rate; the saving between them; the break-even on the costs; and the interest comparison that prices the term reset. Choose the program to apply its cap, its insurance line, or its fee.

Illustrative starting assumptions: a $655,000 home value near Castle Rock’s median owner-occupied value, a $458,000 current balance, a current rate and remaining term you enter, closing costs seeded at $9,000 as an editable placeholder (not a fee quote), a thirty-year term at the current Freddie Mac benchmark, and property taxes and insurance estimated for Colorado (U.S. Census Bureau). Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The new rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a refinance quote; a refinance is priced by the lender at lock, and the current rate, the remaining term and the closing costs are figures you enter. The current payment is estimated from the balance, the current rate and the remaining term; the break-even divides the closing costs by the monthly saving and ignores the interest effect of a longer term. On the VA IRRRL the funding fee is added to the loan unless the veteran is exempt. Taxes and insurance are editable estimates.

Same home, four ways to refinance it.
Same home, four instruments: the conventional rate-and-term that most Castle Rock owners use; the FHA streamline and the VA IRRRL, which only an existing FHA or VA borrower can use; and the jumbo rate-and-term for a balance the conforming limit cannot hold. The cards below compare what each one asks and what it delivers.
Conventional, streamline, or jumbo.
The conventional rate-and-term refinance replaces whatever first mortgage is on the home with an agency loan: value tested by appraisal, leverage capped as in the snapshot, mortgage insurance ending at the line, the old loan and the costs inside the new balance. It asks the most of the file and reaches the most homeowners, including FHA borrowers ready to shed the premium. See the conventional loan program.
The government streamlines refinance the government loan already on the home and nothing else. FHA loans go to FHA loans with no appraisal and a limited review. VA loans go to VA loans with no VA appraisal, the fee inside the loan, and a benefit test. Both follow the agency’s seasoning clock. They are the quickest route to a lower payment or a fixed rate for an eligible Castle Rock owner, and the wrong route for shedding FHA insurance. See the FHA and VA programs.
For balances above the conforming limit, the jumbo lanes refinance rate-and-term with their own rulebook: the score floor in the snapshot on the headline lane, leverage to the lane’s cap, reserves per the lane, and a second appraisal above the lane’s threshold. The arithmetic is the same as any refinance; the file asks more of the Castle Rock borrower’s documents and liquidity. See the jumbo loan program.
Refinance conventionally when the loan is conventional, when an FHA premium should end, or when a borrower must come off the note; use the FHA streamline or the VA IRRRL when the loan is already FHA or VA and the goal is a lower payment or a fixed rate; go to the jumbo lanes when the balance is above the limit. Go to the cash-out guides when the goal is cash.
What to prepare for a Castle Rock scenario review.
The paperwork is the standard refinance set, with the automated finding deciding how much of it the file actually needs and the streamlines asking for far less; here is what a Castle Rock refinance review typically draws on.
This is a general preparation guide, not a universal checklist. The selected lender may request additional information based on the transaction, the property, the automated finding, and the income picture. Nothing here is legal or tax advice.
Local details that can change the loan.
The program is simple to state and particular in its exceptions. Here are the local and file-level details that most often change a Castle Rock refinance between application and closing.
Use these checks to keep the Castle Rock file clean and fundable.
Settle the arithmetic before the paperwork. A Castle Rock refinance that does not recover its costs, or that gives back the saving in added interest, is not improved by a shorter calendar; the review exists to say as much before anything is ordered.
- Run the break-even: Closing costs divided by the monthly saving is the break-even in months.
- Weigh the reset: Read the interest comparison in the calculator before choosing the term.
- Expect the waiting period: A principal-residence refinance funds after the rescission period.
The costs are recovered only through the saving
Closing costs are paid from the loan or at the table, and the only thing that earns them back is the monthly saving. Divide the costs by the saving and the result is the number of months the Castle Rock owner must keep the new loan to come out even; an owner planning to sell or refinance again before then is paying for a loan they will not use.
The term starts over unless you choose a shorter one
Two refinances with the same rate can produce opposite results: one lengthens the loan and lowers the payment, the other shortens it and lowers the total interest. Which is right depends on what the Castle Rock owner needs each month and how long they will hold the home. The calculator’s interest comparison is where that decision is made.
The rescission period on a principal residence
A refinance of the home you live in carries a rescission period after signing, during which the borrower may cancel; the old loan is paid off and the new one funds only after it has run. The first payment on the new loan follows the funding date, and a Castle Rock owner should plan the old loan’s last payment and the new loan’s first around it.
Removing or adding a borrower rewrites the note
A refinance is how a name comes off a mortgage after a divorce, a death, or a change in the household: the remaining borrower qualifies alone, the title is conformed at closing, and the departing borrower’s obligation ends. Paying the departing owner their equity through the loan is a cash-out or a special-purpose refinance, which is a different program.
The loan being replaced may need to be seasoned
A loan a month short of its seasoning cannot be refinanced through the IRRRL until the month passes, and an FHA streamline waits on the previous loan’s seasoning and payment record. The conventional refinance has no such clock, which is one reason a recent FHA or VA borrower sometimes refinances conventionally instead. The Castle Rock review reads the first-payment date before anything else.
From a Castle Rock scenario review to a new first payment.
Four steps, in the order that protects the Castle Rock owner’s money: review the break-even and the program; apply and receive the finding; appraise where the program requires it and underwrite; close, wait out the rescission period on a principal residence, and fund.
Scenario review
Start with the balance, the current rate, the years remaining, the value, the score, and the costs. A Lendmire loan officer identifies the program the existing loan points to, runs the new payment, the saving, the break-even, and the interest comparison, and provides the terms in writing before anything is ordered.
Application and automated finding
The application turns the reviewed scenario into a file. For most Castle Rock refinances the automated finding arrives quickly and lists the documents; for a streamline it is the agency’s checklist instead. Either way the appraisal, where one applies, is ordered only after this step.
Appraisal and underwriting
The appraiser fixes the value and the underwriter confirms the rest: credit, income, assets, the second lien’s origin, the project on a condominium, the seasoning on a streamline or an IRRRL. A value under the plan resizes the loan or moves it across the insurance line; the review was run with room beneath it for exactly that reason.
Closing, rescission, and funding
At closing the new loan is signed, the payoff is ordered, and after the rescission period on a home the borrower lives in, the old loan is retired and the new one begins. Second homes and investment property fund without the wait. The new servicer sends the first statement, and any saving the review showed starts with it.
A brokerage that runs the break-even honestly.
Lendmire is a mortgage brokerage licensed to arrange consumer mortgages in sixteen states, and on a refinance that buys three things: the break-even run honestly, with a plain recommendation not to refinance when the numbers say so; the file shopped across several wholesale programs rather than one; and terms in writing before the appraisal is ordered.
The break-even, run before anything else
A brokerage earns nothing by talking a Castle Rock owner out of a refinance, which is why the honest version of the review is worth having. The break-even and the interest comparison come first, and the answer follows them.
Shopped across wholesale programs
Lendmire places the file with the wholesale program that fits it, conventional, FHA, VA, or jumbo, rather than with the one program a single lender sells. A Castle Rock refinance is compared on the same numbers across programs before a route is chosen.
Terms in writing, before any fee
An appraisal fee on a refinance that cannot pay for itself is money wasted, so the written terms come first and the appraisal second. The owner sees the new loan, the payment, the saving, and the break-even before any fee is charged.

Castle Rock refinance FAQs
The refinance questions a Castle Rock loan officer hears most, answered plainly: when it pays, what it costs, which program, and what the appraisal can do.
What is a rate-and-term refinance, and how is it different from a cash-out?
Rate-and-term means the loan’s terms change and the balance does not, apart from the costs rolled in. A cash-out means the balance grows and the difference is paid to the borrower. The agencies treat them as different transactions with different leverage and different prices, and so does every program on this page.
When does refinancing actually make sense?
When the arithmetic says it should. A refinance is a purchase of a new loan with closing costs as the price, and it pays when what you get, a saving, a fixed rate, a shorter term, an end to insurance, is worth more than the price inside the time you keep it. The break-even is the first test and the interest comparison is the second.
What does a refinance cost to close?
A refinance carries lender and third-party charges, prepaid interest and escrow deposits, and title and recording costs; on a VA IRRRL the funding fee is added unless the veteran is exempt. The figures depend on the loan, the program, and the state, and are stated in the written terms and on the Loan Estimate rather than on this page. They can be paid at closing or, within the program’s rules, rolled into the loan, where they raise the balance and lengthen the break-even slightly.
Can I get rid of mortgage insurance by refinancing?
Yes, in two situations. An FHA borrower can refinance into a conventional loan at or below the no-insurance line in the snapshot and leave the FHA premium behind for good; an FHA streamline does not do this, because FHA insurance stays with an FHA loan. A conventional borrower paying private mortgage insurance may not need a refinance at all: cancellation can be requested at the published line on the original value, and the servicer must end it on its own at the lower line. Where the home’s value has risen enough, a conventional refinance with a new appraisal puts the loan under the line sooner.
What is an FHA streamline, and who can use it?
Use it when your loan is FHA, you intend to stay FHA, and the new loan passes HUD’s net tangible benefit test. Skip it when the goal is ending the premium, which needs a conventional refinance at or below the insurance line, or when the loan is not FHA at all. A Castle Rock loan officer confirms the case details and the payment history first.
Will I need an appraisal, and what if it comes in low?
Yes on the conventional and jumbo routes, no on the government streamlines. Improvements count to the extent the market pays for them, not what they cost. If the figure disappoints, the loan is resized to the cap at that value, the insurance line is re-checked, or the file waits for the market.
What if I want cash out of my home as well?
Read the cash-out guide instead, or the HELOC guide if the current first mortgage is worth keeping. A rate-and-term refinance is the wrong instrument for cash, and the agencies treat a refinance that pays off a later second lien or returns more than incidental cash as a cash-out regardless of what it is called.
How soon after buying or refinancing can I refinance again?
A conventional rate-and-term refinance has no agency waiting period on the loan being replaced, so the question is whether it pays, not whether it is allowed. A VA IRRRL works differently. The loan being replaced must be seasoned, meaning the later of two marks: a set number of days after its first payment date, and a set number of monthly payments made. The VA card in the snapshot higher on this page carries both figures. An FHA streamline is a separate case, because it applies the previous loan’s seasoning and payment-history rules. For any program, a Castle Rock owner who refinanced recently should also count the costs of doing it again against the saving.
Does my state treat a refinance differently?
Mostly no: a rate-and-term refinance follows the program’s rules wherever the home sits, and the figures in the snapshot apply in every state Lendmire serves. A few states add their own conditions to particular loans, most often to loans secured by a homestead or to the refinance of an existing home-equity loan, and where that is the case the state guide on this site carries the detail. A Lendmire loan officer confirms any state rule before the file is sized.
Is the rate in the calculator what I would get?
It is a benchmark, deliberately: Lendmire does not print rates on these pages, because a rate that is not tied to a file is not a rate anyone will receive. The Castle Rock owner tests scenarios against the benchmark and receives the actual terms in writing after the review.
A Castle Rock mortgage, rewritten on current terms.
A Castle Rock refinance starts with arithmetic and ends with written terms. Send the mortgage statement and the goal; the loan officer returns the program, the new loan, the payment, the saving, and the months to break even, and orders nothing until you agree.
