Current conventional guidelines, updated from one source.
Treat these as the program’s fixed points rather than an offer: the minimum down payment for a first-time buyer and for everyone else, the credit floor behind these pages, the leverage at which mortgage insurance begins and the points at which it ends, and the ratio an automated approval allows.
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
Conventional credit works on a slope rather than a cliff: the floor is 620 on the programs Lendmire places loans with, 620 on a manual fixed-rate file and 640 on a manual adjustable, and the score above that sets the loan-level adjustments and the insurance premium. With more than one borrower the automated system reads the average of the median scores.
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.

| 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.
Four rules shape a Sonoma conventional file: leverage by occupancy and buyer, credit scoring that prices rather than gates, mortgage insurance that cancels, and ratios set by the underwriting path. Each is explained below with the reason behind it.
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 Sonoma 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
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 Sonoma 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 Sonoma 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
The automated finding is the hinge of a conventional file: it reads the income, the assets, the credit, and the property, allows a total debt ratio up to the automated maximum, and names the reserves the file must show. A Sonoma underwriter then verifies what the finding assumed.
A lender runs the same math on a Sonoma file with one difference: the insurer’s actual premium replaces the estimate. The estimate here starts at the low end of the published range and is editable, because the real figure depends on the score and the leverage.
Where Sonoma buyers borrow — and how a conforming loan fits.
Start with the market, then the file. The Sonoma 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.
Citywide figures provide general market context, not an appraisal or an income calculation. 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.

Distinct Sonoma neighborhoods, distinct conventional files.
No single conventional file describes Sonoma. The submarkets 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.
Condominium projects
Warrantability decides the Sonoma condominium file: owner-occupancy mix, association finances, litigation, and rental operations all bear on it, and the review is done before the appraisal is ordered so the contract is not carried past the point of no return. Sonoma is home to about 11K people.
Higher-value homes
A high-value Sonoma home can still be a conforming loan when the loan amount fits under the county limit; above it, the jumbo program takes the file with its own leverage, reserves, and appraisal rules. On a one-unit principal residence at Sonoma’s median value, the first-time buyer’s minimum down payment comes to about $29,100 and the standard minimum to about $48,500 — 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.
Year-round primary residences
In a resort market the principal-residence file is the one with the most room: the top leverage, reserves set by the finding alone, and the cost tier the score earns. A Sonoma buyer who lives there full time uses it like any other buyer. The median owner-occupied home value in Sonoma runs near $970,500 on the latest Census estimate.
Second homes and vacation condominiums
The second-home purchase is the resort market’s conventional specialty: more down than a principal residence, part of it from the buyer’s own funds, reserves for both properties, and an occupancy the buyer must actually keep. Roughly 3,435 Sonoma households own their homes on the latest Census estimate — 65% of all households, the pool a conventional purchase joins.
Homes bought for their setting
Homes bought for their setting in Sonoma are eligible as principal residences or second homes at their own leverage; the appraisal, with its thinner set of comparable sales, and the flood determination are the two steps that take longer. Median household income in Sonoma sits near $98,527 on the latest Census estimate.
Workforce neighborhoods
Away from the resort core, Sonoma’s workforce neighborhoods are where the conventional structure fits a local income: modestly priced homes, first-time buyers at the program minimum, and loans well inside the ratio and the limit. About 35% of Sonoma’s households rent — roughly 1,850 renter households on the latest Census estimate.
The rules do not change with the street. Every Sonoma 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 Sonoma buyers put a conforming loan to work.
Sonoma borrowers use conforming loans for reasons that repeat, from the first purchase at the first-time-buyer minimum to the refinance on a home with equity, and the cards below take up the ones that come up most often.
Buy a first home at the first-time-buyer minimum
The first purchase on a conventional loan starts at the first-time buyer’s minimum in the snapshot, with the whole amount allowed as a family gift. A Sonoma buyer with a solid score may pay less each month than on FHA because the insurance is priced on the score and ends; the comparison is run on the actual numbers.
Buy a condominium in a warrantable project
A Sonoma 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 an investment property
The rental purchase is inside the conventional program at a lower leverage than a principal residence: a Sonoma 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
For the Sonoma 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.
Estimate the payment on a Sonoma price before requesting a quote.
Before you ask for a quote, size the payment yourself: the Sonoma 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.

Illustrative starting assumptions: a $750,000 price (the highest price the example uses, which sits below Sonoma’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.
Choosing among conventional, FHA, and VA in Sonoma 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.
This program offers a low down payment for first-time buyers, insurance set by the score and removed once the balance falls below the threshold, and no upfront premium on the monthly structure. Of the three programs compared here, it alone finances second homes and investment property. The cost is a credit standard that prices a weak score heavily.
FHA asks for a small minimum investment that a gift can cover, accepts a forgiving decision score, and charges an upfront premium plus an annual premium that lasts for the term at full leverage. For a Sonoma buyer with a modest score it usually wins; for a strong score the conventional premium is smaller and temporary. See Lendmire’s FHA loan program.
A Sonoma 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.
Choose by profile: a strong score and any down payment point to conventional; a modest score and a small down payment point to FHA; eligibility with full entitlement points to VA. A Sonoma loan officer runs all three on the same numbers before recommending one. Above the conforming limit, see the jumbo loan program.
What to prepare for a Sonoma scenario review.
Gather these before a Sonoma 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.
The percentages tell only part of the story. What a Sonoma 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 Sonoma file clean and fundable.
A Sonoma file that is ready to review has already answered three questions: what leverage and therefore what insurance, what score and therefore what price, and whether the home is inside the agencies’ rules.
- Plan the insurance: the premium is priced on the score and the leverage inside the published range.
- Confirm the score: a self-pulled score can differ from the decision score.
- Structure the contract: second homes and multi-unit homes need the buyer’s own funds above the threshold.
Mortgage insurance: how much, and until when
The premium on a Sonoma 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 Sonoma 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.
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.
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 Sonoma 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.
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 Sonoma buyer who states one occupancy and uses another has misrepresented the loan.
From a Sonoma 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 Sonoma buyer.
Pre-approval
A Sonoma 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 appraisal is a valuation first and a condition report second on a conventional file; a short value re-sizes the loan, and the Sonoma 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 Sonoma 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
The Sonoma closing applies the program’s structure: the insurance premium in the payment while it applies, the escrow account, and no upfront premium on the monthly structure. The buyer moves in within sixty days on a principal residence, and the servicer tracks the balance toward the cancellation thresholds.
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 Sonoma 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 Sonoma 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
What this page shows are the agencies’ parameters and the wholesale overlays; what a specific Sonoma loan gets is a written set of terms from a licensed loan officer after the review. Lendmire is a broker, never the lender.

Sonoma 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 Sonoma 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 Sonoma 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 Sonoma?
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 Sonoma 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 Sonoma 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 Sonoma?
Ask a loan officer for the county’s current limit; it changes yearly and by unit count. Above it, a Sonoma purchase is still possible with a larger down payment on a conforming loan or on a jumbo loan.
What debt-to-income ratio does a conventional loan allow?
The automated ceiling in the snapshot is the most a conventional file can carry, and the finding decides how much of it a particular Sonoma file gets based on the score, the reserves, and the rest of the profile. Manual files are read at the lower pair.
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 Sonoma conventional purchases close with cash to close near the down payment alone.
Can I buy a rental property with a conventional loan?
Rentals of one to four units are eligible. The down payment is larger than on a home the buyer lives in, the finding sets the reserves, and the rental income enters the ratio under the agencies’ rules rather than in full.
Can the down payment be a gift?
Yes, on a principal residence, from a relative or other acceptable donor, documented by letter and transfer. The seller cannot be the source, and on second homes and multi-unit homes above the threshold the buyer contributes a share of their own funds.
Can I get a conventional loan after a bankruptcy or foreclosure?
Yes, with seasoning. The waits run longer than the government programs’ as a rule, which is why a Sonoma buyer inside one often starts on FHA or VA and refinances into conventional later.
The Sonoma conforming file, priced across the market and explained plainly.
Ask for a Sonoma 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.
