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
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
Total debt against gross income, 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.

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.
Every St. Petersburg conventional file is read by an automated underwriting system against the agencies’ guides. The system does not change the rules below; it applies them: how much 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 Florida; for the mortgage insurance cancellation rules, see the CFPB.
Leverage by occupancy and buyer
The agencies lend most on a home the borrower lives in and less as the occupancy changes: a one-unit principal residence reaches the top leverage, with the first-time buyer’s minimum the lowest down payment in the program; two- to four-unit homes, second homes, and investment properties step down from there, as the table in the snapshot shows for a St. Petersburg buyer.
Credit scores and automated underwriting
Conventional credit is priced more than it is gated. The agencies set no minimum score for a loan their automated system approves, the wholesale programs set a floor, and above the floor the score sets the loan-level price adjustments and the mortgage insurance premium. A St. Petersburg buyer with a stronger score pays less on both lines.
Mortgage insurance that cancels
Above the leverage threshold a private insurer covers the lender’s top-slice risk, and the borrower pays for it in the monthly payment. The premium is priced on the score and the leverage, which is why two St. Petersburg buyers at the same price can pay very different amounts, and it is temporary: cancellable at the request point and ended automatically at the termination point on the original value.
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 St. Petersburg 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 St. Petersburg buyers borrow — and how a conforming loan fits.
These numbers are St. Petersburg’s, not any one borrower’s: owner households, median home value, and household income from the U.S. Census Bureau. They give the scale of a typical purchase here; the score, the appraisal, and the household’s own income give the loan.
These are context figures, not underwriting inputs. Higher values mean a larger down payment in dollars and a larger insurance premium; lower values mean a payment that leaves more room under the ratio ceiling. The percentages do not move; what they amount to does.
Data sources: U.S. Census Bureau — ACS 5-Year (2024) housing and population estimates, including tenure, home values, gross rents, and household income.
Distinct St. Petersburg neighborhoods, distinct conventional files.
No single conventional file describes St. Petersburg. The neighborhoods below differ in housing stock, price, occupancy mix, and the appraisal questions they raise, and each one shapes how a conforming loan is put together.
Newer infill and recent construction
New rows and recent infill in St. Petersburg tend to appraise cleanly, which moves the question to the loan amount: a contract near the conforming limit is confirmed against the county figure before the offer, and a loan above it needs a larger down payment or the jumbo program. Median household income in St. Petersburg sits near $75,192 on the latest Census estimate.
Established close-in neighborhoods
Renovated and unrenovated homes sit side by side in St. Petersburg’s established neighborhoods, and the appraisal values each on comparable sales. The leverage, the insurance, and the ratio do not change with the age of the house. About 37% of St. Petersburg’s households rent — roughly 44,329 renter households on the latest Census estimate.
Two-to-four-unit homes
The owner-occupied multi-unit St. Petersburg file is a conventional specialty with its own leverage, its own rent-counting rules, and its own reserve requirement. The buyer in one unit qualifies on the combined picture. On a home at St. Petersburg’s median value, the first-time buyer’s minimum down payment comes to about $11,100 and the standard minimum to about $18,600 — before closing costs, and before the mortgage insurance that comes with either.
Condominiums and townhomes
Townhomes in St. Petersburg 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. Roughly 74,915 St. Petersburg households own their homes on the latest Census estimate — 63% of all households, the pool a conventional purchase joins.
Investor and second-home purchases
An investor buying a St. Petersburg 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. The median owner-occupied home value in St. Petersburg runs near $371,100 on the latest Census estimate.
Higher-value homes
A high-value St. Petersburg 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. St. Petersburg counts a population near 263K within the Tampa-St. Petersburg-Clearwater, FL area.
Across all of St. Petersburg, 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 St. Petersburg 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 St. Petersburg household can use for every home it owns. Four examples follow.
Buy a second home
Conventional financing is the consumer program that reaches a second home: a St. Petersburg buyer brings the down payment the leverage table shows for that occupancy, qualifies on the full payment of both homes, and shows the reserves the finding requires. The home must be for the owner’s use, not a rental business.
Buy a condominium in a warrantable project
A St. Petersburg condominium is a conventional purchase when the project passes the agencies’ review: owner-occupancy mix, budget and reserves, litigation, commercial space, and ownership concentration. The dues enter the ratio, and the leverage follows the occupancy as it would on a house.
Buy with twenty percent down and no insurance
A St. Petersburg buyer with twenty percent down takes the conventional loan’s cleanest form: no mortgage insurance at all, loan-level adjustments at the best tier the score allows, and a payment made of principal, interest, and escrows alone. Second homes and investment property are priced from the same structure.
Refinance or take cash out
A St. Petersburg 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.
Estimate the payment on a St. Petersburg price before requesting a quote.
The program’s own math on your St. Petersburg inputs: price less the down payment, amortized at the benchmark, with the insurance estimate added while the leverage is above the threshold and the escrows added throughout. The actual rate, premium, payment, and costs come in writing from a licensed loan officer.

Editable benchmark: 7.03% as of September 24, 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 $370,000 price near St. Petersburg’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 Florida (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.
The score, the down payment available, VA eligibility, and the expected length of the loan decide which program wins. Here are the three, one next to the other.
Conventional, FHA, or VA.
The program’s strengths are the cancellable insurance, the breadth of occupancies, and a cost structure that rewards a strong score; its weakness is the same structure applied to a weak one. A St. Petersburg buyer with a strong score usually pays less each month here than on FHA.
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 ratio ladder’s room; it rarely wins for a St. Petersburg 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 St. Petersburg household. See Lendmire’s VA loan program.
The decision is rarely close once the profile is known. Conventional tends to win the strong score and every non-primary occupancy, FHA the modest score, and VA 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 St. Petersburg scenario review.
The paperwork is the standard mortgage set, with the automated finding deciding how much of it the file actually needs; here is what a St. Petersburg scenario 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 underwriting finding, and the income picture. Nothing here is legal or tax advice.
Local details that can change the loan.
When a St. Petersburg 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 St. Petersburg 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: the premium is priced on the score and the leverage inside the published range.
- Confirm the score: the score sets the loan-level adjustments and the insurance premium more than it gates the loan.
- Check the project: the project must pass the agencies’ review to be warrantable.
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 St. Petersburg 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 St. Petersburg 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.
Warrantable or not
Project review is the one property question that can take a St. Petersburg condominium out of the program entirely. The lender collects the association’s questionnaire, budget, and insurance before the appraisal, and a buyer under contract should ask early how the project reads.
Waiting periods after a credit event
The agencies season credit events rather than barring them: each bankruptcy chapter, a foreclosure, a deed-in-lieu, and a short sale carry their own period, shortened by documented extenuating circumstances. The snapshot table shows each one for a St. Petersburg buyer planning the timing.
The appraisal and value acceptance
When the value comes in under the contract price on a St. Petersburg file, the loan is sized on the lower figure: the buyer brings the difference, the price is renegotiated, or the contract is released under its appraisal contingency. Condition findings are rarer than on government loans but still appear on older homes.
From a St. Petersburg pre-approval to keys in hand.
From the first conversation to the closing table, a St. Petersburg conventional purchase takes four steps, and each one carries an agency rule inside it.
Pre-approval
Start with the score, the income, the down payment, and the occupancy. A Lendmire loan officer runs the automated system, confirms the leverage and the insurance for the down payment chosen, checks the loan against the conforming limit, compares the structure with FHA and VA on the same numbers, and provides the terms in writing.
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 St. Petersburg contract is adjusted or released under its contingency. Where the system offers value acceptance, the step collapses to the system’s figure.
Underwriting
The underwriter verifies what the automated finding assumed: the income, the assets and reserves, the credit and any seasoning, the occupancy, and the property. A manual file follows the lower ratio pair instead. Conditions are issued, documented, and cleared before the approval is final.
Closing
At closing the loan is funded at the leverage chosen, the mortgage insurance begins with the first payment where the loan sits above the threshold, and the escrows for taxes and insurance are set up. A St. Petersburg buyer signs the note and the security instrument, occupies the home within the occupancy window, and the loan is sold to the agency.
A brokerage that prices the whole market.
Lendmire never lends. It reads a St. Petersburg file against conventional, FHA, and VA, matches the program to the profile, and keeps the premium, the cost tier, and the conforming limit in front of the buyer before anything is signed.
Several programs, one set of numbers
The comparison printed on this page is run for real on every St. Petersburg 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 insurance is the program’s cost and the cancellation rules are its advantage, and Lendmire explains both first rather than last: how much the premium is, which structure fits, and when it ends for a St. Petersburg buyer at the price in hand.
Licensed, consumer-purpose, in writing
Lendmire carries the license for the state the St. Petersburg 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.

St. Petersburg conventional loan FAQs
What a conventional loan is, how much it takes to buy, what score it needs, how the mortgage insurance works and ends, and how the conforming limit works, answered for St. Petersburg buyers.
What is a conventional loan, and who is it for?
A conventional loan is a mortgage written to the rules of Fannie Mae and Freddie Mac so the lender can sell it to them after closing; no government agency insures it, and a private insurer covers the top slice above the leverage threshold. It fits the St. Petersburg buyer with a solid score, any down payment from the program minimum up, and any occupancy the agencies allow, including second homes and rentals.
How much do I need to put down on a conventional loan in St. Petersburg?
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 St. Petersburg 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 St. Petersburg 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?
Above the threshold the insurance is part of the St. Petersburg payment; below it, there is none. Fannie Mae publishes the typical annual range shown in the snapshot, the insurer prices the actual premium, and the federal cancellation rules end it as equity arrives.
What is the conforming loan limit in St. Petersburg?
The limit is the first thing confirmed on a St. Petersburg 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 use a conventional loan to buy a condominium?
Condominiums are eligible in projects that pass the agencies’ review. Resort projects with rental operations, projects in litigation, and buildings with heavy commercial space are the ones that fail; many established St. Petersburg projects pass.
Can I take cash out with a conventional refinance?
Cash-out is a full refinance at the snapshot’s cash-out leverage, available on a principal residence, a second home, or a rental at each one’s limit. Six months of ownership is the general seasoning rule, with exceptions for delayed financing and inheritance.
Can I buy a second home with a conventional loan?
It is the usual route to a St. Petersburg second home, since FHA and VA finance principal residences only. Expect a larger down payment than on a principal residence, deeper reserves, and adjustments for the occupancy.
What happens after my St. Petersburg offer is accepted?
Appraisal first, then underwriting, then conditions, then closing. The appraisal or the value acceptance sets the value; the underwriter verifies what the finding assumed; the closing funds the loan at the leverage chosen and starts a payment with the insurance line if one applies.
Can the seller pay my closing costs on a conventional loan?
Within the cap for the combined loan-to-value, yes: closing costs, prepaids, and points. The down payment is separate and must be the buyer’s own funds or a gift; the seller can cover the rest up to the cap.
Run the St. Petersburg conventional numbers, then get the terms in writing.
Begin with a scenario review: the price, the down payment, the score, the income, and the occupancy. A licensed Lendmire loan officer prices the file across the wholesale programs, runs it beside FHA and VA, and puts the terms in writing.
