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
The agencies set the floor at 3% down for a first-time buyer and 5% for a repeat buyer, on a principal residence; the whole down payment may be a gift from a relative on a one-unit home, and twenty percent down removes mortgage insurance from the payment entirely.
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
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.
| 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.

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 National City 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
The down payment a National City buyer needs depends on three things: whether the home is a principal residence, a second home, or a rental; whether it is one unit or several; and whether the buyer counts as a first-time buyer. The snapshot table gives the answer for every combination the program allows.
Credit scores and automated underwriting
The automated system, DU on the Fannie Mae side and LPA on the Freddie Mac side, reads the whole credit file rather than a single number: the score, the depth of history, the recent events, and the seasoning after any derogatory event. The score it uses with more than one borrower is the average of the median scores.
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 National City file comes from the insurer at lock, never from this page.
Ratios, reserves, and the DU finding
Three things decide what payment a National City income carries: the ratio ceiling for the underwriting path, the reserves the finding requires, and the stability of the income over two years. Enter income in the calculator to see the ratio on a local price before asking for a quote.
Every input below is yours: the National City price, the down payment, the buyer type, the term, the rate, the insurance estimate, and the escrows. The thresholds and the ratio ceiling come from the program; the payment, the insurance, and the cancellation month follow from the arithmetic.
Where National City buyers borrow — and how a conforming loan fits.
The leverage limits are percentages; the market turns them into dollars. The Census figures below describe National City’s ownership, home values, and household income, the backdrop every conforming loan here is sized against.
These are context figures, not underwriting inputs. Higher values mean a larger down payment in dollars and a larger insurance premium; lower values mean a payment that leaves more room under the ratio ceiling. The percentages do not move; what they amount to does.
Data sources: U.S. Census Bureau — ACS 5-Year (2024) housing and population estimates, including tenure, home values, gross rents, and household income.
Distinct National City neighborhoods, distinct conventional files.
One program, several National City submarkets: the cards below describe the housing stock, the price range, and the conventional question that comes up most often in each.
Multi-unit conversions
A converted National City duplex finances on a conventional loan with the buyer in one side and the other side’s rent documented toward the ratio the way the agencies allow. The appraisal reads both units and the rents. The median owner-occupied home value in National City runs near $612,200 on the latest Census estimate.
Newer subdivisions on the bypass
The newer National City subdivisions out by the bypass appraise cleanly, and the system often offers value acceptance; the question is whether the ratio carries the higher price with the insurance added. Roughly 6,330 National City households own their homes on the latest Census estimate — 35% of all households, the pool a conventional purchase joins.
In-town neighborhoods
National City’s in-town blocks hold its oldest houses, and a conventional appraisal reads them for value first; condition notes appear on failing roofs and systems, and sellers usually address them before closing. About 65% of National City’s households rent — roughly 11,887 renter households on the latest Census estimate.
Manufactured homes
National City manufactured homes finance on conventional loans under the agencies’ rules for the home and the site; a home on leased land or without a permanent foundation does not qualify, and the wholesale programs may add conditions. Median household income in National City sits near $66,841 on the latest Census estimate.
Everyday values and the first-time minimum
At National City’s price levels the conventional structure is at its most comfortable: a small down payment that may be a gift, a premium that ends on schedule, and a payment that typically leaves room under the ratio on a local income. National City is home to about 59K people.
Rural-edge and acreage properties
A National City property with land qualifies as a residence. Fewer comparable sales mean a more careful appraisal, and outbuildings beyond residential use are not added to the value. On a one-unit principal residence at National City’s median value, the first-time buyer’s minimum down payment comes to about $18,400 and the standard minimum to about $30,600 — 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.
What the program accepts is the same everywhere in National City: houses, warrantable condominiums, planned developments, manufactured homes that meet the agencies’ rules, two- to four-unit homes, second homes, and investment property, each at its own leverage. What it declines is the non-warrantable project and the loan above the conforming limit, which belong to other programs.
Four ways National City 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 National City borrowers to it most.
Buy a second home
A second home in National City 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.
Buy with twenty percent down and no insurance
A National City buyer with twenty percent down gets the conventional loan’s cleanest form: no mortgage insurance, loan-level adjustments at the best tier the score allows, and a payment of principal, interest, and escrows alone. Second homes and investment property are priced from the same structure.
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 National City 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 National City 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.
Estimate the payment on a National City price before requesting a quote.
The program’s own math on your National City 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.
National City conventional payment estimate
Use the National City defaults as a starting point and change the price, the down payment, the buyer type, the term, the insurance estimate, and the escrows to fit.
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 $610,000 price near National City’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 National City 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.
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 National City buyer with strong credit and a down payment above the minimum. 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 National City principal residence; conventional still wins the second home and rental. 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 National City scenario review.
What a lender reads on a National City 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 National City 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 National City 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 National City files before income is even opened.
- 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.
- Mind the ratios: the total ratio includes the insurance while it applies.
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 National City 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 National City 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.
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 National City buyer with other financed properties carries more of them.
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 National City buyer who states one occupancy and uses another has misrepresented the loan.
The appraisal and value acceptance
When the value comes in under the contract price on a National City file, the loan is sized on the lower figure: the buyer brings the difference, the price is renegotiated, or the contract is released under its appraisal contingency. Condition findings are rarer than on government loans but still appear on older homes.
From a National City pre-approval to keys in hand.
Four steps: the pre-approval, the appraisal, the underwriting, and the closing. The National City version of each follows.
Pre-approval
A National City 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
With the contract signed, the lender orders the appraisal, or accepts the value the automated system offers where a waiver applies. Seller contributions are checked against the cap for the leverage, and a condominium’s project documents are collected for review before the file moves on.
Underwriting
Underwriting on a National City 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 National City 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.
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
A lender with one rate sheet sells that sheet; a brokerage with several can say which fits. For a National City 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 insurance is the program’s cost and the cancellation rules are its advantage, and Lendmire explains both first rather than last: how much the premium is, which structure fits, and when it ends for a National City buyer at the price in hand.

National City 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 National City 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 National City 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 National City?
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 National City 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 National City 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?
It is temporary insurance for the lender, paid by the borrower while the loan sits above the threshold. On a National City loan with scheduled payments the calculator shows the month the balance reaches the request point and the automatic one; extra principal or a rise in value, recognized by the servicer, can bring the request point sooner.
What is the conforming loan limit in National City?
There is a county limit, revised annually, and some counties carry a high-balance range above the standard figure. The loan officer confirms the current limit at pre-approval; above it, the jumbo program takes the file.
How does a conventional refinance work?
Rate-and-term loans reach the higher limit; cash-out loans stay at the lower one. Each applies to a principal residence, second home, or rental at its own leverage. A National City owner with mortgage insurance may also refinance into a loan at or below the threshold and leave the insurance behind.
Can I take cash out with a conventional refinance?
It is available at the cash-out leverage shown in the snapshot, with the occupancy setting the limit and the score setting the price. A National City owner weighs it against a home equity line on the same numbers.
What debt-to-income ratio does a conventional loan allow?
Two paths, all of them total ratios: a single higher ceiling for a file the automated system approves, and for manual underwriting a lower figure, with a higher one available when the matrix’s credit and reserve criteria are met. The housing payment counted includes the insurance while it applies, which is why cancellation lowers the ratio as well as the payment.
Should I choose a conventional loan or FHA?
Choose by profile: conventional for the buyer whose score earns a small, cancellable premium, FHA for the buyer a conventional loan would price heavily. Many National City buyers start on FHA and refinance into conventional once equity and credit allow.
What are HomeReady, Home Possible, and HomeOne?
HomeReady and Home Possible require income at or below a share of the area median and a homeownership education course; HomeOne requires a first-time buyer and nothing about income. All three sit at the top conventional leverage with reduced mortgage insurance coverage.
Conventional, FHA, or VA for National City: compared on your numbers.
When you are ready, a National City review sizes the loan, settles the program and the insurance structure, and produces written terms. Nothing on this page commits anyone to lend.
