Current conventional guidelines, updated from one source.
One guideline source feeds every number here, and the page updates when the source does. These are purchase and refinance parameters; the leverage table underneath covers occupancy by occupancy, and the status lines cover insurance, gifts, and the first-time-buyer programs.
First-time buyer; 5% standard; 97% loan-to-value at the top
3% down is the first-time buyer’s entry point and 5% the standard one, both on a one-unit principal residence; second homes, two- to four-unit homes, and investment properties carry their own leverage limits, listed in the table below.
Priced on the score; no agency minimum with an automated approval
A 620 decision score opens the program on the wholesale side; the agencies set no minimum for an automated approval and 620 to 640 for manual underwriting by loan type. The strongest effect of the score is on cost, through loan-level adjustments and the mortgage insurance premium.
Required above 80% LTV; removed at 80% by request, 78% automatically
Above 80% loan-to-value the loan carries private mortgage insurance; at or below it, none. The insurance cancels on request at 80% of the original value and automatically at 78%, which is the single largest structural difference from FHA, whose premium at full leverage lasts for the term.
With an automated approval; 36% to 45% on a manual file
Lenders compare total debt against gross income, with limits up to 50% on an automated approval and 36% to 45% on a manual file. The housing payment counted includes the mortgage insurance while it applies, which is why cancellation changes the ratio as well as the payment.
| Purpose | Occupancy and program | Maximum LTV |
|---|---|---|
| Purchase | One-unit principal residence, first-time buyer (fixed rate) | 97% |
| Purchase | One-unit principal residence, standard | 95% |
| Purchase | HomeReady / Home Possible (income limits apply) | 97% |
| Purchase | Two- to four-unit principal residence | 95% |
| Purchase | Second home | 90% |
| Purchase | Investment property, one unit | 85% |
| Purchase | Investment property, two to four units | 75% |
| Refinance | Limited cash-out (rate-and-term), one-unit principal residence | 95% |
| Refinance | Cash-out, one-unit principal residence | 80% |
| Refinance | Cash-out, two to four units, second home or investment | 75% |
| Combined LTV | Maximum contribution |
|---|---|
| above 90 percent | 3% of the sales price |
| 75.01 to 90 percent | 6% of the sales price |
| 75 percent or less | 9% of the sales price |
| investment property (any) | 2% of the sales price |
| Event | Waiting period |
|---|---|
| Chapter 7 or 11 bankruptcy | four years from discharge or dismissal (two years with documented extenuating circumstances) |
| Chapter 13 bankruptcy | two years from discharge; four years from dismissal (two with extenuating circumstances) |
| Multiple bankruptcy filings | five years when more than one filing within the past seven years |
| Foreclosure | seven years (three with extenuating circumstances, then limited to a principal residence or second home at 90 percent LTV, purchase or limited cash-out) |
| Deed-in-lieu, short sale or mortgage charge-off | four years (two with extenuating circumstances) |
Mortgage insurance: Fannie Mae reports that private mortgage insurance typically ranged from 0.58%–1.86% of the loan amount a year; the premium on a specific loan is priced by the insurer on the score, the leverage, and the coverage, and is never quoted here. Gifts from relatives may fund the entire down payment on a one-unit principal residence. HomeReady and Home Possible lend to 97% with income at or below 80% of the area median; HomeOne lends to the same leverage with a first-time buyer and no income limit.
Current conventional snapshot · updated October 3, 2026 · principal residences occupied within sixty days, second homes, and one- to four-unit investment properties · conforming limits apply by county and are confirmed by a Lendmire loan officer · above the limit, see the jumbo program · no prepayment penalty · Lendmire is a broker, never the lender.
This page describes program parameters, not an offer. The down payment minimums, the credit floor, the insurance thresholds, and the ratios are agency guidelines and lender overlays, subject to change without notice and to full underwriting; the appraisal, the credit report, the property, the occupancy, and the conforming limit decide every file. Lendmire is a broker, not a lender. Licensed in sixteen states for consumer mortgages. NMLS #2371349.
What a conventional loan is — and how the file is qualified.
Nearly every Fullerton conventional file is read by an automated underwriting system against the agencies’ guides, and the few written by hand follow the manual columns of the same rules. The system does not change the rules below; it applies them: the leverage the occupancy allows, how the score is read, when mortgage insurance attaches and ends, and what the ratios and reserves must show.
For the program overview, see Lendmire’s conventional loan program, or the statewide guide at Conventional Loans in California; for the mortgage insurance cancellation rules, see the CFPB.
Leverage by occupancy and buyer
Leverage on a Fullerton conventional loan is a table rather than a single number: purchase against refinance, principal residence against second home against rental, one unit against several. Each cell has its own maximum, a cash-out refinance sits below the purchase ceiling for the same occupancy, and the snapshot shows the whole table.
Credit scores and automated underwriting
What the score does on a Fullerton conventional file is set the cost. A lower score raises the loan-level adjustments and the insurance premium; a higher score lowers both. Manual underwriting, used when the automated system cannot approve the file, carries its own minimum score and tighter ratios.
Mortgage insurance that cancels
The federal cancellation rules are the quiet advantage of a conventional loan. The borrower can ask to drop the insurance when the balance reaches the request threshold, the servicer must drop it at the automatic threshold, and it cannot outlast the midpoint of the term. On an FHA loan at full leverage the premium stays for the life of the loan.
Ratios, reserves, and the DU finding
Three things decide what payment a Fullerton income carries: the ratio ceiling for the underwriting path, the reserves the finding requires, and the stability of the income over two years. Enter income in the calculator to see the ratio on a local price before asking for a quote.
The calculator runs this on a Fullerton scenario and adds the piece most calculators skip: the month on the amortization schedule when the balance reaches the request and automatic-termination thresholds, so the payment after the insurance ends is visible beside the payment before.
Where Fullerton buyers borrow — and how a conforming loan fits.
Start with the market, then the file. The Fullerton figures below set the backdrop for a conventional purchase: who owns, what homes are worth on the latest estimate, and what households earn, which together decide what a first-time buyer’s down payment and payment look like locally.
These are context figures, not underwriting inputs. Two buyers at the same score can see different files here: one buys at the median and sits well inside the ratio, another stretches above it and needs reserves and a stronger finding. The market sets the spread.
Data sources: U.S. Census Bureau — ACS 5-Year (2024) housing and population estimates, including tenure, home values, gross rents, and household income.
Distinct Fullerton neighborhoods, distinct conventional files.
One program, several Fullerton submarkets: the cards below describe the housing stock, the price range, and the conventional question that comes up most often in each.
Condominiums and townhomes
Townhomes in Fullerton finance like houses when they are fee simple and like condominiums when they are organized as one; the lender settles which before the appraisal, and the leverage follows the occupancy either way. The median owner-occupied home value in Fullerton runs near $902,600 on the latest Census estimate.
Investor and second-home purchases
An investor buying a Fullerton unit to rent uses the conventional program at the investment leverage, documents the rent the agencies allow, and shows reserves for every financed property; the agencies cap how many such loans one borrower may carry. About 48% of Fullerton’s households rent — roughly 23,170 renter households on the latest Census estimate.
Higher-value homes
A high-value Fullerton purchase can still be a conforming loan when the loan amount fits under the county limit, and a high-cost county’s higher range extends that reach; above it, the jumbo program takes the file with its own leverage and reserves. On a one-unit principal residence at Fullerton’s median value, the first-time buyer’s minimum down payment comes to about $27,100 and the standard minimum to about $45,100 — before closing costs, and before the mortgage insurance that comes with either; a second home, a multi-unit home, or a rental starts higher, as the leverage table shows.
Established close-in neighborhoods
An older Fullerton house is a routine conventional purchase; the appraisal is lighter on condition than a government appraisal, which is one reason buyers of older homes often choose this program. The value against the contract price is the usual question. Median household income in Fullerton sits near $104,286 on the latest Census estimate.
Two-to-four-unit homes
Owner occupancy of one unit sets the leverage on a Fullerton multi-unit conventional loan; without it, the property is an investment purchase at the lower investment leverage. The appraisal reads every unit and the rents. Roughly 24,947 Fullerton households own their homes on the latest Census estimate — 52% of all households, the pool a conventional purchase joins.
Newer infill and recent construction
New rows and recent infill in Fullerton tend to appraise cleanly, so the loan amount is the question: a contract near the conforming limit is checked against the county figure before the offer, and a loan above it needs a larger down payment or the jumbo program. Fullerton is home to about 141K people.
Across all of Fullerton, five questions settle a conventional loan: what the appraisal supports, whether the property passes the agencies’ review, how the home will be occupied, what the score costs, and what the ratio and reserves allow.
Four ways Fullerton buyers put a conforming loan to work.
The conventional loan is one of the broadest mortgage programs there is: it buys a first home with a small down payment, a move-up home with cancellable insurance, a second home, and a rental, and it refinances all of them. The cards below are the uses that bring Fullerton borrowers to it most.
Buy an investment property
Investment property on a conforming loan is a common entry point for Fullerton landlords: one to four units, a down payment set by the leverage table, rental income counted under the agencies’ rules, and a cap on how many financed properties one borrower may hold.
Buy a second home
For the Fullerton vacation or weekend home, the conforming loan is usually the only consumer route: FHA and VA finance principal residences only. The down payment is larger, the reserves are deeper, and the score prices the loan the same way it does on any conventional purchase.
Refinance or take cash out
A Fullerton owner can refinance a conventional loan two ways: a limited cash-out refinance to the rate-and-term leverage in the snapshot, or a cash-out refinance to the lower cash-out leverage after the seasoning period, on a principal residence, second home, or rental at each occupancy’s own limit.
Buy with twenty percent down and no insurance
Twenty percent down removes the insurance line from the payment on any conventional purchase in Fullerton; between the minimum and twenty percent, the insurance applies for a while and then ends, and the calculator shows both payments.
Estimate the payment on a Fullerton price before requesting a quote.
Before you ask for a quote, size the payment yourself: the Fullerton price, the down payment, the term, the benchmark rate, the insurance estimate, and the escrows go in, and the thresholds and the ratio ceiling come from the same guideline source as the block above. The result is an estimate, the rate is a published market average, and the insurance figure is an editable estimate inside Fannie Mae’s published range.
Fullerton conventional payment estimate
The defaults are a Fullerton starting point, not your purchase: put in the real price, the real down payment, and the real escrows.
Editable benchmark: 7.28% as of October 1, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a conventional loan quote.
Estimate seeded at the low end of Fannie Mae’s published range (0.58%–1.86% a year); the insurer prices the actual premium on the score and the leverage. Applies only above 80% loan-to-value.
Illustrative starting assumptions: a $750,000 price (the highest price the example uses, which sits below Fullerton’s median owner-occupied home value), the first-time buyer’s minimum down payment, a thirty-year term at the current Freddie Mac benchmark, mortgage insurance at the low end of Fannie Mae’s published range, property taxes and insurance estimated for California (U.S. Census Bureau). Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a conventional loan quote; your rate is set by the lender at lock. The mortgage insurance figure is an editable estimate seeded from Fannie Mae’s published typical range, not a premium quote; the insurer prices the actual premium, and the cancellation month assumes scheduled payments with no extra principal and no change in value. Taxes, insurance and dues are editable estimates; closing costs are not included. Conforming loan limits apply by county. Licensed in sixteen states for consumer mortgages.
Same buyer, three very different closings.
Most buyers can close the same purchase three ways, and the structures differ more than the labels suggest: conventional with insurance that cancels, FHA with a small investment and premiums for the life of the loan at full leverage, or VA with nothing down and no insurance for the eligible veteran.
Conventional, FHA, or VA.
Conventional fits the Fullerton buyer with a solid score: the premium is smaller than FHA’s for strong credit and it ends, the monthly structure carries no upfront premium, and twenty percent down removes insurance altogether. A modest score or a thin file is where FHA competes.
Where conventional prices the score, FHA prices by schedule. FHA fits the buyer whose score would be priced heavily on a conventional loan, or who needs the room FHA’s ratio tiers allow; it rarely wins for a Fullerton buyer with strong credit and a down payment above the minimum. See Lendmire’s FHA loan program.
VA beats conventional on the principal residence for nearly every eligible borrower; conventional beats VA on everything VA does not touch: second homes, rentals, and buyers without the certificate. The two often sit side by side in one Fullerton household. See Lendmire’s VA loan program.
The decision is rarely close once the profile is known. Conventional tends to win for a strong score and for every non-primary occupancy, FHA for a modest score, and VA for nearly any eligible principal residence. The comparison is run on the actual numbers, in writing. Above the conforming limit, see the jumbo loan program.
What to prepare for a Fullerton scenario review.
What a lender reads on a Fullerton conventional loan, and what you can have ready before anyone asks.
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 underwriting finding, and the income picture. Nothing here is legal or tax advice.
Local details that can change the loan.
The percentages tell only part of the story. What a Fullerton conventional loan actually becomes depends on the score, the appraisal, the project review, and the automated finding, and these are the details that move it.
Use these checks to keep the Fullerton file clean and fundable.
Three things to settle before a Fullerton review: how the mortgage insurance will be structured and when it ends, where the decision score lands and what it prices, and whether the property has any agency question attached.
- Plan the insurance: the premium is priced on the score and the leverage inside the published range.
- Confirm the score: the lender’s report sets the decision score; multiple borrowers use the average of the median scores.
- Check the limit: conforming limits are set by county and unit count and reset every year.
Mortgage insurance: how much, and until when
The premium on a Fullerton loan can be paid monthly, paid by the lender in exchange for a different price, paid as a single premium at closing, or split. The monthly structure cancels under the federal rules, and the others are set by the lender. The calculator shows the monthly structure and the month the thresholds arrive on scheduled payments.
The score sets the cost
The decision score comes from the lender’s report, and with multiple borrowers the automated system uses the average of the median scores. On a Fullerton conventional file the score rarely ends eligibility, but it sets the loan-level adjustments and insurance premium, so a few points can change monthly cost.
The conforming limit
Conforming loans are capped by county and by unit count, with higher limits in high-cost areas, and the FHFA resets the figures each year. A Fullerton purchase whose loan would run above the limit brings a larger down payment, uses the high-balance range where the county has one, or moves to jumbo; a loan officer confirms the current county limit.
The appraisal and value acceptance
A conventional appraisal values the Fullerton home and reports on condition without a HUD or VA property standard; the home must be safe, sound, and marketable. The automated system sometimes offers value acceptance or an appraisal waiver, in which case no appraisal is ordered and the file closes on the system’s valuation.
Seller contributions and the down payment
Two rules shape the Fullerton contract: the contribution cap, which falls as the leverage rises, and the source rules for the down payment, which allow a full gift on a one-unit principal residence and require a share of the buyer’s own funds on second homes and multi-unit homes above the threshold.
From a Fullerton pre-approval to keys in hand.
A conventional purchase runs in a fixed order: pre-approval through the automated system on the score, the ratio, and the reserves; contract and appraisal or value acceptance; underwriting that verifies what the finding assumed; and closing with the insurance structure set. Here is that order for a Fullerton buyer.
Pre-approval
A Fullerton pre-approval is a sizing exercise run through the automated system: the score, the income, the assets, the occupancy, and the price. The finding sets the ratio room and the reserves, and the loan officer puts the pre-approval in writing for the offer.
Contract and appraisal
The Fullerton contract sets the price and the contributions; the appraisal, or the system’s value acceptance, sets the value. Both feed the loan amount, and the lender confirms the project review and the conforming limit before underwriting begins.
Underwriting
The underwriter verifies what the automated finding assumed: income, assets and reserves, credit and any seasoning, occupancy, and the property. A manual file follows the lower ratio pair instead. Conditions are issued, documented, and cleared before final approval.
Closing
Closing is where the structure becomes a payment: principal and interest, the insurance while the loan is above the threshold, taxes and insurance. The Fullerton buyer takes the keys, and the lender delivers the loan to the agency it was written for.
A brokerage that prices the whole market.
Lendmire is a mortgage brokerage licensed for consumer lending in sixteen states, and on a conventional loan that buys three things: the file priced across several wholesale programs rather than one, the insurance structure and its exit explained before an offer is written, and the terms in writing from a licensed loan officer.
Several programs, one set of numbers
A lender with one rate sheet sells that sheet; a brokerage with several can say which fits. For a Fullerton buyer with a strong score that is usually a conventional loan on the program whose cost is lowest for that file; for a modest score it may be FHA, and the arithmetic decides.
The insurance explained before the offer
No Fullerton buyer should learn at the closing table what the insurance costs or how long it lasts. The loan officer walks through the premium for the leverage chosen, the month the thresholds arrive on scheduled payments, and the alternative of a larger down payment.
Licensed, consumer-purpose, in writing
Lendmire carries the license for the state the Fullerton home is in, delivers the disclosures a consumer mortgage requires, and commits the terms to paper. The program figures on this page are read from one guideline source built on the agencies’ published guides.

Fullerton conventional loan FAQs
Plain answers to the questions Fullerton buyers ask most about conventional loans, in the order they usually ask them.
What is a conventional loan, and who is it for?
Think of it as the mortgage without a federal guaranty or insurance: the agencies set the rules, a private insurer covers the high-leverage slice, and the score sets the price. Principal residences, second homes, and one- to four-unit rentals are all inside it.
How much do I need to put down on a conventional loan in Fullerton?
It depends on who is buying and how the home will be used. A first-time buyer starts at the lowest figure in the snapshot, a repeat buyer slightly higher, and a Fullerton second home or rental higher still. Twenty percent down removes mortgage insurance entirely.
What credit score do I need for a conventional loan?
The floor in the snapshot opens the program; the score above it sets the cost. With more than one borrower the automated system uses the average of the median scores, and a Fullerton buyer close to a cost tier may gain from a short wait and a paid-down balance.
How does private mortgage insurance work, and when does it end?
Mortgage insurance applies when the loan runs above the leverage threshold in the snapshot and is paid monthly as part of the payment. The premium is priced by the insurer on the score and the leverage, inside the published range the snapshot shows. Under the Homeowners Protection Act the borrower may request cancellation at the request threshold on the original value, the servicer must terminate it automatically at the termination threshold, and it ends no later than the midpoint of the term.
What is the conforming loan limit in Fullerton?
Ask a loan officer for the county’s current limit; it changes yearly and by unit count. Above it, a Fullerton purchase is still possible with a larger down payment on a conforming loan or on a jumbo loan.
What does the appraisal check on a conventional loan?
The value and the general condition. A conventional appraisal is lighter on condition than a government appraisal, and a short value re-sizes the loan on a Fullerton file; the buyer brings the difference, renegotiates, or releases the contract under its contingency.
Can I take cash out with a conventional refinance?
A conventional cash-out refinance replaces the first mortgage with a larger loan at the cash-out leverage and hands over the difference. A Fullerton owner with a low-balance first mortgage usually compares a second lien first.
Should I choose a conventional loan or FHA?
Conventional tends to fit the buyer with a strong score, because its insurance cancels and carries no upfront premium; FHA tends to fit the buyer with a modest score, because its ratios stretch further. The answer for a Fullerton buyer comes from the numbers, not the label.
Can I buy a rental property with a conventional loan?
Yes, one to four units, at the investment leverage in the snapshot table, with the rental income counted toward qualifying under the agencies’ rules and reserves required for each financed property. The agencies also cap the number of financed properties one borrower may hold, and the loan is written under their investment-property rules rather than as an investor DSCR loan.
Is a conventional loan assumable?
Not the fixed-rate loan. Some conventional ARMs permit assumption, and the note says which. A Fullerton owner thinking about selling into a higher-rate market should know the loan does not transfer.
The Fullerton conforming file, priced across the market and explained plainly.
Ask for a Fullerton scenario review to confirm the leverage, the insurance and its exit, and the loan the program supports. Lendmire is a broker licensed in sixteen states for consumer mortgages and is never the lender.
