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
3% down is the first-time buyer’s entry point and 5% the standard one, both on a one-unit principal residence; second homes, two- to four-unit homes, and investment properties carry their own leverage limits, listed in the table below.
Priced on the score; no agency minimum with an automated approval
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
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.
Four rules shape a San Diego conventional file: leverage by occupancy and buyer, credit scoring that prices rather than gates, mortgage insurance that cancels, and ratios set by the automated finding. 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
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 San Diego 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 San Diego buyer with a stronger score pays less on both lines.
Mortgage insurance that cancels
Insurance structures vary: borrower-paid monthly is the default, and lender-paid, single-premium, and split-premium versions exist, each built into the loan differently. The published typical range in the snapshot is Fannie Mae’s, and the actual premium for a San Diego file comes from the insurer at lock, never from this page.
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.
None of this is a decision. The appraisal can come in under the price, the rate is set at lock, the premium is set by the insurer, and the automated finding sets the reserves. What stays fixed is the structure the calculator reproduces: price, down payment, leverage, insurance, payment.
Where San Diego buyers borrow — and how a conforming loan fits.
Start with the market, then the file. The San Diego 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. 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 San Diego neighborhoods, distinct conventional files.
The house and its use decide the file as much as the borrower. These San Diego submarkets differ in the property types, the occupancies, and the prices a typical buyer carries, which is what the cards below describe.
Investor and second-home purchases
San Diego rentals and pied-à-terre purchases run on conventional loans because FHA and VA finance principal residences only: the investment and second-home leverage in the snapshot, reserves for each financed property, and adjustments for the occupancy. The median owner-occupied home value in San Diego runs near $906,700 on the latest Census estimate.
Higher-value homes
The higher-value San Diego 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 53% of San Diego’s households rent — roughly 279,312 renter households on the latest Census estimate.
Two-to-four-unit homes
The owner-occupied multi-unit San Diego 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 San Diego’s median value, the first-time buyer’s minimum down payment comes to about $27,200 and the standard minimum to about $45,300 — before closing costs, and before the mortgage insurance that comes with either.
Newer infill and recent construction
New rows and recent infill in San Diego 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 San Diego sits near $108,077 on the latest Census estimate.
Established close-in neighborhoods
Renovated and unrenovated homes sit side by side in San Diego’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. Roughly 251,100 San Diego households own their homes on the latest Census estimate — 47% of all households, the pool a conventional purchase joins.
Condominiums and townhomes
Much of San Diego’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. San Diego counts a population near 1.39M within the San Diego-Chula Vista-Carlsbad, CA area.
Across all of San Diego, 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 San Diego 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 San Diego household can use for every home it owns. Four examples follow.
Buy a first home at the first-time-buyer minimum
For a San Diego first purchase, the conventional route pairs the agencies’ lowest down payment with insurance that cancels and no upfront premium; the file is qualified on the score, the ratio, the reserves, and the automated finding, and a family gift may fund the whole down payment.
Buy a condominium in a warrantable project
The condominium file adds the project review to the house file. Once a San Diego 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.
Buy a second home
For the San Diego vacation or weekend home, the conforming loan is usually the only consumer route: FHA and VA finance principal residences only. The down payment is larger, the reserves are deeper, and the score prices the loan the same way it does on any conventional purchase.
Refinance or take cash out
Refinancing on a conventional loan follows the same leverage table as buying: rate-and-term to the higher limit, cash-out to the lower one. A San Diego owner who has carried mortgage insurance may also use the refinance to leave it behind once the new loan sits at or below the threshold.
Estimate the payment on a San Diego price before requesting a quote.
The program’s own math on your San Diego 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.

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.
The alternatives put the conventional loan’s cost in perspective: FHA charges a premium every month and an upfront premium at closing, VA charges a one-time fee, conventional charges a premium only until equity arrives. The comparison below is written for a San Diego buyer weighing all three.
Conventional, FHA, or VA.
Conventional fits the San Diego buyer with a solid score: the premium is smaller than FHA’s for strong credit and it ends, there is no upfront premium, and twenty percent down removes insurance altogether. A modest score or a thin file is where FHA competes.
FHA’s leverage is high and its credit standard is forgiving, but its insurance is priced by schedule rather than by score and does not cancel on a full-leverage thirty-year loan. A San Diego buyer comparing the two sees the premium line stay on FHA and disappear on conventional. See Lendmire’s FHA loan program.
A San Diego 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.
Where each one fits: conventional for the solid score, the move-up buyer, the second home, and the rental; FHA for the modest score and the small investment; VA for the eligible borrower buying a principal residence. Above the conforming limit, see the jumbo loan program.
What to prepare for a San Diego scenario review.
What a lender reads on a San Diego 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.
A handful of details decide whether a San Diego conventional file closes as planned, closes at a different cost, or stalls. These are the ones that come up most.
Use these checks to keep the San Diego file clean and fundable.
The list is short because the program is: the insurance, the score, and the property decide most San Diego files before income is even opened.
- Plan the insurance: it cancels on request at the request threshold and automatically at the termination threshold.
- Confirm the score: the score sets the loan-level adjustments and the insurance premium more than it gates the loan.
- Structure the contract: contributions are capped by the combined loan-to-value, as the snapshot shows.
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 San Diego 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 San Diego 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.
Seller contributions and the down payment
A San Diego contract can shift most closing costs to the seller inside the cap for the leverage, which leaves the buyer bringing the down payment and little else. On second homes and two- to four-unit homes above the threshold, part of the down payment must be the buyer’s own funds.
Waiting periods after a credit event
A documented hardship beyond the borrower’s control, such as a job loss or a medical event, can shorten several of the waiting periods, and the shortened foreclosure period limits the leverage and the occupancy. A San Diego file inside a waiting period is written later, not now.
The conforming limit
Conforming loans are capped by county and by unit count, with higher limits in high-cost areas, and the figures are reset each year by the FHFA. A San Diego purchase whose loan would run above the limit either brings a larger down payment to fit under it or moves to the jumbo program; a Lendmire loan officer confirms the current limit for the county.
From a San Diego pre-approval to keys in hand.
Underneath, the San Diego process is any mortgage process; what makes it conventional is the automated finding, the project review where it applies, the leverage by occupancy, and the insurance threshold. Each step below says what happens and what the buyer does.
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 San Diego 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 San Diego 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 San Diego conventional file is a verification of the finding: the documents behind the 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 San Diego closing applies the program’s structure: the insurance premium in the payment while it applies, the escrow account, and no upfront premium. 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.
The case for a brokerage on a conventional loan is candor with numbers: the same file priced across programs, the insurance premium and its cancellation month stated outright, the leverage checked against the occupancy, and the terms in writing.
Several programs, one set of numbers
Before any recommendation, the San Diego file is priced across the wholesale programs Lendmire works with and run against FHA and VA on the same price, score, and down payment. The buyer sees the payment, the insurance line, and the cash to close for each, and the choice follows the figures.
The insurance explained before the offer
No San Diego 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.

San Diego 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 San Diego buyers.
What is a conventional loan, and who is it for?
Conventional means conforming: a loan inside the conforming limit, qualified by an automated underwriting system against the agencies’ rules. A San Diego buyer applies through a lender or broker, the lender follows the guides, and the agency buys the loan.
How much do I need to put down on a conventional loan in San Diego?
The first-time buyer’s minimum in the snapshot on a one-unit principal residence with a fixed rate, where a first-time buyer is anyone without an ownership interest in a home during the prior three years; the standard minimum for everyone else; and more for second homes, multi-unit homes, and investment property, as the leverage table shows. A relative’s gift may fund the whole down payment on a one-unit principal residence.
What credit score do I need for a conventional loan?
The wholesale programs behind these pages start at the floor shown in the snapshot. Fannie Mae itself sets no minimum score for a loan its automated system approves and a minimum only for manually underwritten loans; what the score mostly does is set the price of the loan and the mortgage insurance, so a San Diego buyer above the floor still benefits from every tier gained.
How does private mortgage insurance work, and when does it end?
Three dates matter: the month the balance reaches the request threshold, when the borrower can ask the servicer to drop the premium with a good payment history; the month it reaches the termination threshold, when the servicer must drop it; and the midpoint of the term, the final backstop. Twenty percent down means none of this applies.
What is the conforming loan limit in San Diego?
The limit is the first thing confirmed on a San Diego 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.
Can I get a conventional loan after a bankruptcy or foreclosure?
Each event has its own period counted from a specific date, and the lender confirms it from the documents. Clean credit since the event and a rebuilt score carry weight once the period has run.
Should I choose a conventional loan or FHA?
It depends on the score, the down payment, and how long you will keep the loan. Conventional prices the insurance on the score and cancels it; FHA prices by schedule and keeps it for the term at full leverage. A strong score usually pays less on conventional; a modest score usually pays less on FHA. A San Diego loan officer runs both in writing.
How does a conventional refinance work?
A conventional refinance has its own rows in the leverage table, below the purchase rows. The limited cash-out version changes the loan’s terms; the cash-out version borrows against equity and generally needs six months of ownership first.
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.
