Current conventional guidelines, updated from one source.
The block below is the conforming rulebook reduced to the figures that decide a file, read from Lendmire’s single guideline source and refreshed on this page when the agencies or the wholesale overlays change: the down payment by buyer, the credit floor, the mortgage insurance threshold and its cancellation points, and the ratio maximums.
First-time buyer; 5% standard; 97% loan-to-value at the top
On a principal residence the down payment starts at 3% for a first-time buyer and 5% otherwise, the top leverage being 97% loan-to-value. Second homes and investment properties ask for more, as the leverage table shows, and the price of any leverage above 80% is mortgage insurance.
Priced on the score; no agency minimum with an automated approval
620 is the working floor, a wholesale overlay rather than an agency rule, since Fannie Mae requires no minimum score for a loan the automated system approves and 620 only on a manual fixed-rate file. Above the floor, each step up in score lowers the cost of the loan and of the insurance.
Required above 80% LTV; removed at 80% by request, 78% automatically
The insurance line in a conventional payment is a bridge, not a fixture: required above 80% loan-to-value, cancellable at 80% on request and 78% by law, and priced by the insurer on the score inside Fannie Mae’s published 0.58%–1.86% range. Twenty percent down skips it entirely.
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.

What a conventional loan is — and how the file is qualified.
Nearly every Troy 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 Michigan; for the mortgage insurance cancellation rules, see the CFPB.
Leverage by occupancy and buyer
The down payment a Troy buyer needs depends on three things: whether the home is a principal residence, a second home, or a rental; whether it is one unit or several; and whether the buyer counts as a first-time buyer. The snapshot table gives the answer for every combination the program allows.
Credit scores and automated underwriting
The automated system reads the score and the credit events together, and a derogatory event does not end eligibility; it starts a clock. Bankruptcies, foreclosures, short sales, and deed-in-lieu transfers each carry a waiting period in the agencies’ guides, shortened by documented extenuating circumstances, and the snapshot shows each one for a Troy buyer.
Mortgage insurance that cancels
Twenty percent down means no mortgage insurance at all, and anything less means insurance for a while. The calculator on this page shows the Troy payment with the estimated premium and the payment after it ends, along with the month on the amortization schedule when the request and automatic thresholds arrive.
Ratios, reserves, and the DU finding
Total debt-to-income is the ratio that counts: the full housing payment, insurance included, plus every monthly obligation, against gross income. Automated approvals reach the higher ceiling in the snapshot; manual files are held to the lower pair, with the higher of the two needing the matrix’s credit and reserve criteria.
The calculator runs this on a Troy 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 Troy buyers borrow — and how a conforming loan fits.
Conventional loans are sized against a local market, and these are Troy’s numbers from the U.S. Census Bureau: how many households own, what a typical home is worth, and what households earn. Together they set the scale of a typical down payment, loan, and insurance premium.
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 Troy neighborhoods, distinct conventional files.
One program, several Troy submarkets: the cards below describe the housing stock, the price range, and the conventional question that comes up most often in each.
Higher-value homes
On Troy’s higher-value homes, a conventional loan hits the conforming limit first. Buyers over it can bring a larger down payment to fit under it, use the high-balance range where the county has one, or choose the jumbo program. A loan officer confirms the current limit before the offer. Median household income in Troy sits near $120,045 on the latest Census estimate.
Newer infill and recent construction
On recent construction in Troy the appraisal is usually uneventful and the arithmetic decides: whether the loan fits under the conforming limit, and whether the ratio carries the price once the insurance is added at the leverage chosen. On a one-unit principal residence at Troy’s median value, the first-time buyer’s minimum down payment comes to about $12,600 and the standard minimum to about $21,000 — 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.
Condominiums and townhomes
Much of Troy’s entry-level stock is attached housing, and a conventional loan finances it whenever the project is warrantable under the agencies’ review. The dues go into the ratio, and the first-time buyer’s minimum applies as it would on a house. About 27% of Troy’s households rent — roughly 8,926 renter households on the latest Census estimate.
Investor and second-home purchases
Troy rentals and pied-à-terre purchases run on conventional loans because FHA and VA finance principal residences only. Conventional terms include investment and second-home leverage in the snapshot, reserves for each financed property, and adjustments for the occupancy. Troy is home to about 88K people and sits within the Detroit-Warren-Dearborn, MI area.
Two-to-four-unit homes
Owner occupancy of one unit sets the leverage on a Troy 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 24,446 Troy households own their homes on the latest Census estimate — 73% of all households, the pool a conventional purchase joins.
Established close-in neighborhoods
An older Troy 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. The median owner-occupied home value in Troy runs near $420,300 on the latest Census estimate.
The rules do not change with the street. Every Troy file is checked the same way: price against the appraisal, property against the agencies’ standards, condominium against the project review, occupancy against its leverage limit, and borrower against the score, the ratios, and the reserves the finding requires.
Four ways Troy buyers put a conforming loan to work.
Because the agencies buy loans on principal residences, second homes, and investment property alike, the conventional loan is a program a Troy household can use for every home it owns. Four examples follow.
Buy an investment property
The rental purchase is inside the conventional program at a lower leverage than a principal residence: a Troy buyer uses the agencies’ rules for counting rental income, shows reserves for every property financed, and accepts loan-level adjustments that reflect the occupancy.
Buy a second home
A second home in Troy is a conventional file with its own leverage and reserve rules: more down than a principal residence, the payment on the existing home counted in the ratio, and a property the owner occupies part of the year rather than rents full time.
Buy with twenty percent down and no insurance
A Troy buyer with twenty percent down gets the conventional loan’s cleanest form: no mortgage insurance, loan-level adjustments at the best tier the score allows, and a payment of principal, interest, and escrows alone. Second homes and investment property are priced from the same structure.
Buy a condominium in a warrantable project
The condominium file adds the project review to the house file. Once a Troy project clears it, the first-time buyer’s minimum, the insurance rules, and the ratio ceiling are exactly what they would be on a single-family home.
Estimate the payment on a Troy price before requesting a quote.
Before you ask for a quote, size the payment yourself: the Troy 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.
Troy conventional payment estimate
The defaults are a Troy 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 $420,000 price near Troy’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 Michigan (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.

Same buyer, three very different closings.
Choosing among conventional, FHA, and VA in Troy is really choosing an insurance structure and a credit standard at the same time. Each is laid out below with the buyer it fits.
Conventional, FHA, or VA.
Conventional fits the Troy 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 Troy buyer with strong credit and a down payment above the minimum. See Lendmire’s FHA loan program.
A Troy buyer with VA eligibility and full entitlement rarely needs a conventional loan for a principal residence: nothing down, no insurance, and residual-income underwriting. Conventional is the route for that same veteran’s second home or investment property, which VA does not finance. 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 Troy scenario review.
Gather these before a Troy review: the ordinary mortgage documents, plus the pieces that settle the first-time-buyer question and the occupancy.
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.
When a Troy conventional file surprises someone, the cause is usually one of these: a premium higher than expected, a score that priced differently than hoped, an appraisal under the price, a project that failed review, or a loan amount over the conforming limit.
Use these checks to keep the Troy file clean and fundable.
Before asking for a quote, know three answers: how much insurance the leverage carries and for how long, what the score does to the price, and whether the property and the loan amount fit the conforming program.
- Plan the insurance: twenty percent down carries no insurance at all.
- Confirm the score: a self-pulled score can differ from the decision score.
- Match the occupancy: the stated occupancy must be the real one.
Mortgage insurance: how much, and until when
Cancellation on request needs a good payment history, no subordinate liens, and no decline in value; automatic termination needs only that the loan be current. A Troy owner whose home has gained value may also ask the servicer to recognize the current value under its own rules, which is a servicer decision rather than a program right.
The score sets the cost
The score does two jobs on a Troy file: it feeds the automated assessment alongside the rest of the credit file, and it sets the cost of the loan and the insurance. A buyer close to a cost tier sometimes gains more from a short wait and a paid-down balance than from any other change.
Occupancy and its leverage
Each occupancy has its own leverage limit and loan-level adjustments: a principal residence occupied within sixty days of closing reaches the top of the table, a second home is lower, an investment property lower still. A Troy buyer who states one occupancy and uses another has misrepresented the loan.
Second homes, rentals, and financed-property limits
A Troy household can hold several conventional loans at once, but each financed property adds reserves to the next file and the agencies cap the number of financed properties a borrower may have. Second homes and rentals are leveraged lower than a principal residence and priced for the occupancy.
The appraisal and value acceptance
A conventional appraisal values the Troy 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.
From a Troy pre-approval to keys in hand.
Four steps: the pre-approval, the appraisal, the underwriting, and the closing. The Troy version of each follows.
Pre-approval
The first conversation settles the shape: whether the buyer counts as a first-time buyer, what leverage the occupancy allows, how much insurance the down payment carries, and whether conventional is the right program next to FHA and VA for the Troy purchase.
Contract and appraisal
The appraisal is a valuation first and a condition report second on a conventional file; a short value re-sizes the loan, and the Troy contract is adjusted or released under its contingency. Where the system offers value acceptance, the step collapses to the system’s figure.
Underwriting
Underwriting on a Troy conventional file verifies the finding: the documents behind income and assets, the source of the down payment, the project review, and the insurance commitment for the leverage. Conditions are cleared and the approval is issued with its terms.
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 Troy 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
The comparison printed on this page is run for real on every Troy file: conventional with the insurer’s actual premium beside FHA with its premiums beside VA where eligibility exists, and the written terms follow from it.
The insurance explained before the offer
The premium and its exit are decided by the leverage and the score, and a buyer should know both before signing a contract. Lendmire states the structure for the Troy purchase, shows the payment before and after cancellation, and explains the request and automatic thresholds.
Licensed, consumer-purpose, in writing
What this page shows are the agencies’ parameters and the wholesale overlays; what a specific Troy loan gets is a written set of terms from a licensed loan officer after the review. Lendmire is a broker, never the lender.

Troy conventional loan FAQs
The questions below come up on nearly every Troy conventional conversation. The answers are general; the figures in the snapshot above are the program’s current parameters.
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 Troy?
Less than most people expect on a principal residence, and it can be a gift from family. The trade for a small down payment is mortgage insurance, which cancels as the balance falls; the calculator shows the Troy payment with it and without it.
What credit score do I need for a conventional loan?
The practical answer is the floor in the snapshot, and the useful answer is that every tier above it lowers the cost. A Troy buyer with a modest score should run FHA beside conventional, because FHA prices its insurance by schedule rather than by score.
How does private mortgage insurance work, and when does it end?
The premium is a percentage of the loan a year, divided into the monthly payment, and it is set by the insurer on the score and the leverage rather than by a government schedule. It cancels: by request at the request threshold, automatically at the termination threshold, and no later than the midpoint of the term.
What is the conforming loan limit in Troy?
The limit is the first thing confirmed on a Troy file near the top of the market. These pages state the program’s structure rather than a number that changes every year; the current figure comes from a loan officer.
Can I buy a second home with a conventional loan?
Yes, at the second-home leverage in the snapshot table. The home must be occupied by the owner part of the year and not operated as a rental business; a property rented full time is an investment property under the program.
What are HomeReady, Home Possible, and HomeOne?
HomeReady and Home Possible require income at or below a share of the area median and a homeownership education course; HomeOne requires a first-time buyer and nothing about income. All three sit at the top conventional leverage with reduced mortgage insurance coverage.
Can I take cash out with a conventional refinance?
Yes, at the leverage in the snapshot for the occupancy, after the seasoning period. The cash-out loan carries its own loan-level adjustments, and the loan-to-value decides whether mortgage insurance applies to the new loan.
What happens after my Troy offer is accepted?
Your Troy contract goes to the lender, the appraisal is ordered or waived, and underwriting follows. The usual detours are a value under the price or a condition on an older home; a loan officer keeps the timeline honest.
How does a conventional refinance work?
Conventional refinances come in two shapes, each with its own leverage in the snapshot. The appraisal, or value acceptance where the system offers it, sets the value; the score prices the loan; and the occupancy sets the limit.
Run the Troy conventional numbers, then get the terms in writing.
When you are ready, a Troy review sizes the loan, settles the program and the insurance structure, and produces written terms. Nothing on this page commits anyone to lend.
