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
First-time buyers (no ownership interest in a home in the past three years) can put 3% down on a one-unit principal residence with a fixed rate, at 97% LTV. Others start at 5% down. HomeReady and Home Possible give lower-income buyers the same 97%.
Priced on the score; no agency minimum with an automated approval
The wholesale programs behind these pages start at a 620 decision score. The agencies themselves set no minimum for an automated approval and ask for 620 on a manually underwritten fixed-rate loan and 640 on an adjustable; the score prices the loan and the insurance more than it gates them.
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.

What a conventional loan is — and how the file is qualified.
A conventional loan is a mortgage written to the rules of Fannie Mae and Freddie Mac so a lender can sell it to them after closing. Those rules decide the leverage by occupancy, the credit standard, the insurance above the threshold, and the ratios, and the four cards below take a Petaluma file apart along exactly those lines.
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 Petaluma 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
Conventional credit is priced more than it is gated. The floor in the snapshot is the lowest score the lanes accept, and above the floor the score sets the loan-level price adjustments and the mortgage insurance premium. A Petaluma buyer with a stronger score pays less on both lines.
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
Reserves are measured in months of the total housing payment and set by the finding, the occupancy, and the number of financed properties; a Petaluma second-home or investment file carries more than a principal residence. Income needs a two-year history and a reasonable expectation of continuing.
The calculator runs this on a Petaluma 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 Petaluma buyers borrow — and how a conforming loan fits.
Start with the market, then the file. The Petaluma 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 Petaluma neighborhoods, distinct conventional files.
Where Petaluma buyers shop, and what the conforming file turns on in each place: the occupancy, the property type the appraiser sees, the project review it needs, and the price the ratio has to carry.
Condominiums and townhomes
Townhomes in Petaluma 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 15,643 Petaluma households own their homes on the latest Census estimate — 65% of all households, the pool a conventional purchase joins.
Investor and second-home purchases
An investor buying a Petaluma 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. Petaluma is home to about 59K people and sits within the Santa Rosa-Petaluma, CA area.
Two-to-four-unit homes
Petaluma duplexes and small apartment houses are conventional purchases at the multi-unit leverage in the snapshot when the buyer occupies one unit, with rent from the other units counted toward qualifying under the agencies’ rules. The median owner-occupied home value in Petaluma runs near $878,600 on the latest Census estimate.
Established close-in neighborhoods
The Petaluma blocks nearest the core carry the oldest houses, and a conventional appraisal reads them for value first and condition second: no HUD or VA property standard, but the home must be safe, sound, and marketable, and a failing roof or system still draws a condition note. Median household income in Petaluma sits near $115,430 on the latest Census estimate.
Higher-value homes
The higher-value Petaluma file is a limit question, not an eligibility question. The conforming limit caps the loan amount, and the buyer either adds down payment to fit under it or chooses the jumbo route for the whole purchase. About 35% of Petaluma’s households rent — roughly 8,596 renter households on the latest Census estimate.
Newer infill and recent construction
A newer Petaluma home rarely draws condition notes; the file turns on the limit and the ratio at the higher price, with the insurance premium added to the payment where the leverage runs above the threshold. On a one-unit principal residence at Petaluma’s median value, the first-time buyer’s minimum down payment comes to about $26,400 and the standard minimum to about $43,900 — 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.
Neighborhood sets the price, the property type, and often the occupancy; the agencies set the rest. The leverage table, the insurance thresholds, the ratio ceiling, and the waiting periods apply identically on every Petaluma file.
Four ways Petaluma 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 Petaluma borrowers to it most.
Buy a condominium in a warrantable project
Condominiums are a common first purchase in Petaluma, and a warrantable project is financed like a house with the dues in the ratio; a project that fails the review is outside the conforming program and goes to a portfolio lender instead.
Buy with twenty percent down and no insurance
The move-up Petaluma buyer selling one home and bringing twenty percent to the next usually lands here: no mortgage insurance, the strongest cost tier the score earns, and a loan the automated system reviews with the equity brought forward counted in the file.
Buy a first home at the first-time-buyer minimum
A Petaluma buyer who has not owned a home in three years qualifies for the program’s smallest down payment on a one-unit principal residence with a fixed rate; the down payment can be a gift from a relative, the seller can pay closing costs within the cap, and the insurance cancels as equity grows.
Buy a second home
A second home in Petaluma 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.
Estimate the payment on a Petaluma price before requesting a quote.
Before you ask for a quote, size the payment yourself: the Petaluma 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.
Petaluma conventional payment estimate
The starting figures are a Petaluma price at the first-time buyer’s minimum down payment. Replace them with yours.
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 Petaluma’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.
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 Petaluma 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 room FHA’s ratio tiers allow; it rarely wins for a Petaluma buyer with strong credit and a down payment above the minimum. See Lendmire’s FHA loan program.
A Petaluma 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 Petaluma scenario review.
What a lender reads on a Petaluma 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 Petaluma 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 Petaluma file clean and fundable.
The list is short because the program is simple at its core: the insurance, the score, and the property decide most Petaluma files before income is even opened.
- Plan the insurance: twenty percent down carries no insurance at all.
- Confirm the score: the score sets the loan-level adjustments and the insurance premium more than it gates the loan.
- Check the limit: conforming limits are set by county and unit count and reset every year.
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 Petaluma 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 decision score comes from the lender’s report, and with multiple borrowers the automated system uses the average of the median scores. On a Petaluma 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 Petaluma 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.
Seller contributions and the down payment
Sellers and other interested parties may pay closing costs, prepaids, and other concessions up to a cap set by the combined loan-to-value, as the snapshot table shows; above the cap the excess reduces the price for sizing the loan. The down payment cannot come from the seller, but a relative’s gift can fund it on a one-unit principal residence.
Ratios, reserves, and the finding
The total ratio counts the full housing payment, insurance included, plus every other obligation, against gross income, up to the automated ceiling in the snapshot; a manual file is held to the lower pair. The finding also sets the reserves, and a Petaluma buyer with other financed properties carries more of them.
From a Petaluma pre-approval to keys in hand.
From the first conversation to the closing table, a Petaluma conventional purchase takes four steps, and each one carries an agency rule inside it.
Pre-approval
A Petaluma 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 Petaluma 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
At closing the loan funds at the chosen leverage, mortgage insurance starts with the first payment if the loan is above the threshold, and escrows for taxes and insurance are set up. A Petaluma buyer signs the note and security instrument, occupies the home within the occupancy window, and the agency buys the loan.
A brokerage that prices the whole market.
Lendmire never lends. It reads a Petaluma 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
A lender with one rate sheet sells that sheet; a brokerage with several can say which fits. For a Petaluma 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
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 Petaluma purchase, shows the payment before and after cancellation, and explains the request and automatic thresholds.
Licensed, consumer-purpose, in writing
Lendmire is licensed in sixteen states for consumer mortgages, each owner-occupied loan is a consumer-purpose transaction with a full set of disclosures, and every figure a Petaluma buyer relies on, from leverage to premium to final terms, comes in writing from a licensed loan officer.

Petaluma 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 Petaluma buyers.
What is a conventional loan, and who is it for?
The general-purpose mortgage: conforming to the agencies’ guides, priced on the credit score, insured privately only while the leverage is above the threshold. It is the program most Petaluma buyers compare first and, of the three compared here, the one that reaches a second home or an investment property.
How much do I need to put down on a conventional loan in Petaluma?
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 Petaluma second home or rental higher still. Twenty percent down removes mortgage insurance entirely.
What credit score do I need for a conventional loan?
A conventional loan prices credit rather than simply gating it. The practical floor is the wholesale overlay in the snapshot; the agencies’ own minimum applies only to manual underwriting. Above the floor, the premium and the loan-level adjustments fall as the score rises.
How does private mortgage insurance work, and when does it end?
Above the threshold the insurance is part of the Petaluma 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 Petaluma?
The limit changes every year and differs by county and unit count, so ask a loan officer for the current figure. It caps the loan, not the price: a Petaluma buyer above it brings a larger down payment or uses a jumbo loan.
What debt-to-income ratio does a conventional loan allow?
It depends on the underwriting path. The snapshot shows the automated maximum and the manual pair; enter income in the calculator to see where a Petaluma scenario lands against the automated figure.
How does a conventional refinance work?
It depends on the goal: you can change the rate or term with a limited cash-out refinance, or borrow against equity with a cash-out refinance. Each has its own leverage, and a Petaluma loan officer compares either with a home equity line before recommending one.
Can the seller pay my closing costs on a conventional loan?
They can, and the cap depends on the leverage: more room at lower leverage, less at higher. That is how many Petaluma conventional purchases close with cash to close near the down payment alone.
What happens after my Petaluma 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.
Should I choose a conventional loan or FHA?
Neither is better in general. Conventional insurance cancels; FHA’s does not at full leverage. FHA’s score threshold is lower; conventional’s premium is cheaper for strong credit. The loan officer compares them in writing.
A Petaluma conventional loan sized to the price, the score, and the leverage.
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.
