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
An automated approval allows a total debt-to-income ratio up to 50%; a manually underwritten file is held to 36%, or 45% when credit score and reserves meet the agencies’ matrix. The ratio divides total housing payment plus other monthly obligations by gross income.
| Purpose | Occupancy and program | Maximum LTV |
|---|---|---|
| Purchase | One-unit principal residence, first-time buyer (fixed rate) | 97% |
| Purchase | One-unit principal residence, standard | 95% |
| Purchase | HomeReady / Home Possible (income limits apply) | 97% |
| Purchase | Two- to four-unit principal residence | 95% |
| Purchase | Second home | 90% |
| Purchase | Investment property, one unit | 85% |
| Purchase | Investment property, two to four units | 75% |
| Refinance | Limited cash-out (rate-and-term), one-unit principal residence | 95% |
| Refinance | Cash-out, one-unit principal residence | 80% |
| Refinance | Cash-out, two to four units, second home or investment | 75% |
| Combined LTV | Maximum contribution |
|---|---|
| above 90 percent | 3% of the sales price |
| 75.01 to 90 percent | 6% of the sales price |
| 75 percent or less | 9% of the sales price |
| investment property (any) | 2% of the sales price |
| Event | Waiting period |
|---|---|
| Chapter 7 or 11 bankruptcy | four years from discharge or dismissal (two years with documented extenuating circumstances) |
| Chapter 13 bankruptcy | two years from discharge; four years from dismissal (two with extenuating circumstances) |
| Multiple bankruptcy filings | five years when more than one filing within the past seven years |
| Foreclosure | seven years (three with extenuating circumstances, then limited to a principal residence or second home at 90 percent LTV, purchase or limited cash-out) |
| Deed-in-lieu, short sale or mortgage charge-off | four years (two with extenuating circumstances) |
Mortgage insurance: Fannie Mae reports that private mortgage insurance typically ranged from 0.58%–1.86% of the loan amount a year; the premium on a specific loan is priced by the insurer on the score, the leverage, and the coverage, and is never quoted here. Gifts from relatives may fund the entire down payment on a one-unit principal residence. HomeReady and Home Possible lend to 97% with income at or below 80% of the area median; HomeOne lends to the same leverage with a first-time buyer and no income limit.

What a conventional loan is — and how the file is qualified.
Nearly every San Luis Obispo conventional file is read by an automated underwriting system against the agencies’ guides, and the few written by hand follow the manual columns of the same rules. The system does not change the rules below; it applies them: the leverage the occupancy allows, how the score is read, when mortgage insurance attaches and ends, and what the ratios and reserves must show.
For the program overview, see Lendmire’s conventional loan program, or the statewide guide at Conventional Loans in 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 Luis Obispo buyer.
Credit scores and automated underwriting
What the score does on a San Luis Obispo conventional file is set the cost. A lower score raises the loan-level adjustments and the insurance premium; a higher score lowers both. Manual underwriting, used when the automated system cannot approve the file, carries its own minimum score and tighter ratios.
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 Luis Obispo 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 Luis Obispo buyers borrow — and how a conforming loan fits.
Three Census figures frame a San Luis Obispo conventional file. Ownership says how much of the market the program reaches, the median value says what a low-down-payment loan typically comes to, and household income says what ratio that payment produces.
Market context only. Income sets the ratio, value sets the loan and the premium, and the down payment sets the leverage. The Census describes the first two for the market; the file supplies all three for the borrower.
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 Luis Obispo neighborhoods, distinct conventional files.
No single conventional file describes San Luis Obispo. 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.
Investor and second-home purchases
A second home in San Luis Obispo, occupied part of the year and never run as a rental business, is a conventional file at the second-home leverage with deeper reserves and part of the down payment from the buyer’s own funds. Roughly 8,228 San Luis Obispo households own their homes on the latest Census estimate — 40% of all households, the pool a conventional purchase joins.
Two-to-four-unit homes
San Luis Obispo 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 San Luis Obispo runs near $935,100 on the latest Census estimate.
Condominiums and townhomes
Much of San Luis Obispo’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 Luis Obispo is home to about 48K people and sits within the San Luis Obispo-Paso Robles, CA area.
Established close-in neighborhoods
Renovated and unrenovated homes sit side by side in San Luis Obispo’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. On a one-unit principal residence at San Luis Obispo’s median value, the first-time buyer’s minimum down payment comes to about $28,100 and the standard minimum to about $46,800 — 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.
Higher-value homes
The higher-value San Luis Obispo 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 60% of San Luis Obispo’s households rent — roughly 12,213 renter households on the latest Census estimate.
Newer infill and recent construction
New rows and recent infill in San Luis Obispo tend to appraise cleanly, so the loan amount is the question: a contract near the conforming limit is checked 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 Luis Obispo sits near $73,685 on the latest Census estimate.
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 San Luis Obispo file.
Four ways San Luis Obispo buyers put a conforming loan to work.
San Luis Obispo 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 with twenty percent down and no insurance
The move-up San Luis Obispo 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 an investment property
A San Luis Obispo investor buying one to four units on a conventional loan puts down what the leverage table shows for investment property, documents agency-allowed rent toward qualifying, and holds reserves the finding requires per financed property. It is an individual agency loan under investment-property rules, not an investor DSCR loan.
Buy a second home
Conventional financing is the consumer program that reaches a second home: a San Luis Obispo 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.
Refinance or take cash out
A San Luis Obispo 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 San Luis Obispo price before requesting a quote.
This is what a San Luis Obispo conventional purchase costs each month at the leverage you choose, with the insurance shown as a separate line and then removed: the calculator finds the month on the schedule when the balance reaches the request threshold and the month it reaches the automatic threshold, and shows the payment on each side. The rate shown is the weekly Freddie Mac average, editable, and not a quote.
San Luis Obispo conventional payment estimate
The defaults are a San Luis Obispo starting point, not your purchase: put in the real price, the real down payment, and the real escrows.
Editable benchmark: 7.28% as of October 1, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a conventional loan quote.
Estimate seeded at the low end of Fannie Mae’s published range (0.58%–1.86% a year); the insurer prices the actual premium on the score and the leverage. Applies only above 80% loan-to-value.
Illustrative starting assumptions: a $750,000 price (the highest price the example uses, which sits below San Luis Obispo’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 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 Luis Obispo buyer weighing all three.
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’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 Luis Obispo buyer comparing the two sees the premium line stay on FHA and disappear on conventional. See Lendmire’s FHA loan program.
For an eligible veteran, service member, or surviving spouse, the VA loan drops the down payment and monthly insurance for a one-time funding fee that many disabled veterans do not pay. Where eligible, it usually beats conventional for a San Luis Obispo principal residence; conventional still wins the second home and rental. 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 San Luis Obispo 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 San Luis Obispo scenario review.
What a lender reads on a San Luis Obispo 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.
What moves a San Luis Obispo file most often: the insurance and its cancellation, the score and the cost it sets, the appraisal, the condominium review, the conforming limit, the ratio and the reserves, the occupancy rule, and the seasoning after a credit event.
Use these checks to keep the San Luis Obispo 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: a self-pulled score can differ from the decision score.
- Count the properties: second homes and rentals carry lower leverage than a principal residence.
Mortgage insurance: how much, and until when
The premium on a San Luis Obispo 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 San Luis Obispo 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.
Second homes, rentals, and financed-property limits
Of the three programs compared on this page, the conventional loan is the one that reaches a San Luis Obispo second home or rental, and it does so with conditions: lower leverage, deeper reserves, adjustments for the occupancy, and a limit on the number of financed properties one borrower may carry.
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 San Luis Obispo 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.
Warrantable or not
Project review is the one property question that can take a San Luis Obispo 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.
From a San Luis Obispo pre-approval to keys in hand.
From the first conversation to the closing table, a San Luis Obispo conventional purchase takes four steps, and each one carries an agency rule inside it.
Pre-approval
A San Luis Obispo 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 San Luis Obispo contract is adjusted or released under its contingency. Where the system offers value acceptance, the step collapses to the system’s figure.
Underwriting
The automated finding says what the file needs; the underwriter confirms the file has it. A San Luis Obispo buyer who gathered the documents at pre-approval clears conditions quickly; one who did not spends the time here.
Closing
Closing is where the structure becomes a payment: principal and interest, the insurance while the loan is above the threshold, taxes and insurance. The San Luis Obispo buyer takes the keys, and the lender delivers the loan to the agency it was written for.
A brokerage that prices the whole market.
Lendmire is a mortgage brokerage licensed for consumer lending in sixteen states, and on a conventional loan that buys three things: the file priced across several wholesale programs rather than one, the insurance structure and its exit explained before an offer is written, and the terms in writing from a licensed loan officer.
Several programs, one set of numbers
Before any recommendation, the San Luis Obispo 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
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 San Luis Obispo purchase, shows the payment before and after cancellation, and explains the request and automatic thresholds.
Licensed, consumer-purpose, in writing
Lendmire carries the license for the state the San Luis Obispo 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.

San Luis Obispo 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 Luis Obispo 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 San Luis Obispo 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 San Luis Obispo?
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 San Luis Obispo second home or rental higher still. Twenty percent down removes mortgage insurance entirely.
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 Luis Obispo buyer above the floor still benefits from every tier gained.
How does private mortgage insurance work, and when does it end?
Above the threshold the insurance is part of the San Luis Obispo 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 San Luis Obispo?
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 San Luis Obispo buyer above it brings a larger down payment or uses a jumbo loan.
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 San Luis Obispo projects pass.
What are HomeReady, Home Possible, and HomeOne?
They are the agencies’ affordable programs: the same conforming loan with the top leverage, lower insurance coverage, and in two cases an income limit. A San Luis Obispo buyer who qualifies usually pays less than on the standard conventional structure at the same leverage.
Is a conventional loan assumable?
Not the fixed-rate loan. Some conventional ARMs permit assumption, and the note says which. A San Luis Obispo owner thinking about selling into a higher-rate market should know the loan does not transfer.
Can the seller pay my closing costs on a conventional loan?
Sellers and other interested parties may pay closing costs, prepaids, and other concessions up to the cap for the leverage. A San Luis Obispo contract structured inside the cap leaves the buyer bringing the down payment and little else.
Should I choose a conventional loan or FHA?
Conventional tends to fit the buyer with a strong score, because its insurance cancels and carries no upfront premium; FHA tends to fit the buyer with a modest score, because its ratios stretch further. The answer for a San Luis Obispo buyer comes from the numbers, not the label.
The San Luis Obispo conforming file, priced across the market and explained plainly.
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.
