How to Buy a Home in San Diego County With a VA Loan: Entitlement, the Funding Fee, Residual Income, and the Real Monthly Math (October 2026)

San Diego County is home to 183,791 veterans, according to the U.S. Census Bureau's 2020-2024 American Community Survey, plus thousands of active-duty service members and their families. For many of them, the VA-backed home loan is the most powerful tool they have for buying a home here, because in most cases it allows a purchase with no down payment and no monthly mortgage insurance.

It also has rules that confuse a lot of buyers: entitlement, the funding fee, residual income, the VA appraisal, and the 4% cap on seller concessions. This guide explains each one in plain language, runs the numbers on a median-priced San Diego County home at this week's mortgage rates, and walks through the steps from getting your Certificate of Eligibility to closing.

The San Diego County market right now

Realtor.com's September 2026 county data shows:

• Median listing price: $888,450, down 6.3% from a year earlier and down 1.2% from August.
• Active listings: 5,749, down 1.5% from a year earlier.
• New listings in September: 2,326. Pending listings: 2,137.
• Median days on market: 46, about 6% faster than a year earlier.
• Price-cut share (Realtor.com's price_reduced_share): 20.4% of listings had a price reduction.
• Median listing price per square foot: $587, on a median home size of 1,507 square feet.

For comparison across Southern California in September 2026:

San Diego homes still sell faster than anywhere else in the five-county region, but about one in five listings has cut its price. For a VA buyer, that matters: a seller who has already reduced the price may be more open to paying closing costs, which VA rules allow (more on the limits below).

The rate. Freddie Mac's 30-year fixed average (Primary Mortgage Market Survey) was 7.32% for the week of October 22, 2026, down from 7.40% the week before. That is a survey of conventional loans. VA rates are set by each lender and are often different, so treat 7.32% as an illustration and get real VA quotes.

Step 1: Confirm you are eligible and get your Certificate of Eligibility (COE)

The COE is the document that proves to a lender that you can use the VA home loan benefit, and it shows your entitlement.

Who generally qualifies (from VA's eligibility rules):

• Veterans who served since August 2, 1990, generally need at least 24 continuous months of active duty, or the full period (at least 90 days) they were called or ordered to active duty. Less is allowed if you were discharged for a service-connected disability.
• Earlier service periods have their own minimums (90 days or 181 days, depending on the era).
• National Guard and Reserve members can qualify with at least 90 days of qualifying active-duty service, or with 6 creditable years of service.
• Some surviving spouses qualify.
• An other-than-honorable, bad-conduct, or dishonorable discharge may make you ineligible.

How to do it:

1. Request the COE online through VA.gov, or ask your lender to request it for you. Lenders can often pull it in minutes.
2. Have your documents ready. Veterans need their discharge or separation papers (DD214). Active-duty members need a statement of service signed by their commander, adjutant, or personnel officer showing name, Social Security number, date of birth, entry date, any lost time, and the command providing it. Guard and Reserve members have their own document list on VA.gov.
3. Read the COE carefully. If it says your basic entitlement is $36,000, you have full entitlement. If it shows prior loans charged to your entitlement, you will need Step 2.

Step 2: Understand entitlement, and whether there is a loan limit for you

This is where many San Diego buyers get tripped up.

If you have full entitlement, VA says you don't have a loan limit, as long as you can afford the payment and the appraisal supports the price. VA guarantees up to 25% of the loan to the lender, which is why lenders accept no down payment. Your COE shows full entitlement as "basic entitlement $36,000." You generally have full entitlement if you have never used the benefit, or you used it and repaid the loan in full and sold the home (or had entitlement restored).

If you have partial entitlement (for example, you still own a home bought with an earlier VA loan), the county loan limit comes back into play. VA uses the Federal Housing Finance Agency's conforming loan limit. San Diego County's 2026 one-unit limit is $1,104,000.

How to run your remaining entitlement (VA's method):

1. Find the entitlement already charged on your COE (the "Entitlement Charged" column).
2. Multiply the county limit by 25%: $1,104,000 x 0.25 = $276,000.
3. Subtract what you've used. *Hypothetical:* if your COE shows $100,000 charged, $276,000 - $100,000 = $176,000 remaining.
4. Multiply by 4 to estimate the most that most lenders will lend with no down payment: $176,000 x 4 = $704,000.
5. If you want to borrow more than that, most lenders require your remaining entitlement plus a down payment to cover 25% of the loan amount.

The $100,000 figure above is hypothetical, used only to show the math. Use the numbers on your own COE.

Step 3: Know the VA funding fee, and whether you are exempt

The VA funding fee is a one-time charge, a percentage of the loan amount. You can pay it at closing or finance it into the loan. VA's purchase-loan rates (effective April 7, 2023, still current on VA.gov):

You don't pay the funding fee at all if you receive VA compensation for a service-connected disability (or are eligible but receive retirement or active-duty pay instead), you're a surviving spouse receiving Dependency and Indemnity Compensation, you're a service member with a proposed or memorandum rating before closing showing eligibility for compensation, or you're an active-duty member who provides evidence of a Purple Heart on or before closing. If you later get a disability rating retroactive to before your closing date, you may be eligible for a refund.

How to do it: ask your lender to confirm your exemption status from the COE before you get a Loan Estimate. On a median-priced San Diego home, the exemption is worth about $19,100 on a first-use, zero-down loan.

Step 4: Run the monthly numbers on a median-priced home

Here is the math on San Diego County's September median listing price of $888,450, at the 7.32% PMMS rate for illustration, 30-year fixed. The funding fee is financed. These are principal and interest only.

What this tells you:

• The zero-down VA payment is about $1,350 a month higher than a 20%-down conventional loan, but it keeps about $177,700 in your pocket, and VA loans carry no monthly mortgage insurance.
• Moving from 0% to 5% down cuts the funding fee from 2.15% to 1.5% and lowers the payment by about $350 a month. If you have savings, run both.
• If you are exempt from the funding fee, subtract the fee from the loan amount. On the zero-down example, the payment would be about $6,103 instead of $6,234.

How to run your own numbers:

1. Start with the price you are targeting, not the county median.
2. Subtract any down payment to get the base loan.
3. Multiply the base loan by your funding fee percentage (or zero if exempt), and add it if you're financing it.
4. Use a mortgage calculator or the formula *payment = loan x r / (1 - (1 + r)^-360)*, where r is the annual rate divided by 12.
5. Add property tax, homeowners insurance, and any HOA or Mello-Roos to get the full housing payment.

Step 5: Learn how VA lenders actually qualify you: debt-to-income and residual income

VA underwriting looks at two tests, both set out in federal regulation (38 CFR 36.4340).

Debt-to-income (DTI). Your total monthly housing payment (principal, interest, taxes, insurance, HOA and special assessments) plus long-term debts, divided by gross monthly income. VA's standard is 41% or less. Going above 41% isn't an automatic denial, but the lender has to justify it. If your residual income is at least 20% above VA's guideline, that justification is generally not required.

Residual income. This is what's left each month after taxes, the housing payment, maintenance and utilities, and debts. VA sets minimums by region and family size. California is in the West region. For loans of $80,000 and above, the West minimums are:

Every household member counts, even a spouse who isn't on the loan, unless that spouse's own stable income is verified. VA's lender handbook tells underwriters to estimate maintenance and utilities at 14 cents per square foot of living area. On San Diego's median 1,507-square-foot home, that is about $211 a month.

A worked example (hypothetical household):

The household, its income, its taxes, its debts, the 1.15% property tax rate, and the $1,800 insurance premium below are hypothetical, used only to show the method.

A family of four buys the $888,450 median home with 0% down on a first-use VA loan.

• DTI: if gross income is a hypothetical $20,000 a month, ($7,236 + $400) / $20,000 = about 38%, under the 41% standard.
• Income at exactly 41% DTI: ($7,236 + $400) / 0.41 = about $18,624 a month, or about $223,500 a year.
• Residual income: $20,000 gross, minus a hypothetical $5,000 in federal and state income tax and Social Security, minus $7,236 housing, $211 maintenance and utilities, and $400 debts leaves about $7,153, far above the $1,117 West minimum for a family of four.

For context, San Diego County's median household income is $106,268 (Census, 2020-2024), about $8,856 a month. That gap is why many VA buyers here look below the county median, at condos and townhomes, or in North County inland and East County communities, or buy with a spouse's income or a larger down payment.

How to do it:

1. Add up your gross monthly income from all borrowers. Ask your lender exactly which income it will count, such as military allowances or VA disability compensation, and what documents it needs.
2. List every monthly debt from your credit report, plus child support and child care.
3. Run DTI at your target price. If you're over 41%, check residual income against the table above.
4. VA doesn't set a minimum credit score, but most lenders do. Ask at least two or three lenders for their minimum and their rate.

Step 6: Shop VA lenders and compare Loan Estimates

VA doesn't set your rate, discount points, or most closing costs; the lender does, and these vary from lender to lender.

How to do it:

1. Get Loan Estimates from at least three lenders on the same day, for the same loan amount and lock period.
2. Compare the rate, the points (Section A of the Loan Estimate), and total cash to close.
3. Confirm each lender has applied your funding fee exemption, if you have one.
4. Get a full preapproval, not just a prequalification, before you make offers. In a county where homes go pending in a median of 46 days, a strong preapproval letter matters.

Step 7: Write an offer that works for a VA buyer

Seller concessions. VA doesn't limit what a seller can pay toward your normal closing costs, but it caps *seller concessions* at 4% of the home's reasonable value. Concessions include things like the seller paying your funding fee, paying off your debts, or prepaying your hazard insurance. On an $888,450 home, 4% is about $35,538.

Closing costs you can't finance. On a VA purchase loan, only the funding fee can be rolled into the loan. Everything else (title, escrow, appraisal, prepaid items) has to be paid at closing, by you, the seller, or a lender credit.

How to negotiate:

1. Check the listing's price history. With 20.4% of San Diego listings showing a price cut in September, a reduced listing is a natural place to ask for closing-cost help.
2. Ask the seller to cover your closing costs or pay for a rate buydown, instead of (or in addition to) a lower price. Run both: a credit may lower your cash to close more than a small price cut.
3. Keep your terms clean otherwise: a reasonable escrow length, a solid preapproval, and a clear explanation that VA appraisals and inspections are routine.

Step 8: Prepare for the VA appraisal

VA orders the appraisal and issues a Notice of Value showing the home's reasonable value. VA's maximum loan is the lower of the appraised value or the purchase price. If the appraisal comes in below the price, you can renegotiate, pay the difference in cash, or request a reconsideration of value with better comparable sales.

How to do it:

1. Before you write the offer, ask your agent to review recent comparable sales so your price is supportable.
2. Expect the appraiser to look at basic safety and soundness, such as roof, water heater, and peeling paint on older homes. Ask the seller up front about any known issues.
3. Still get your own home inspection. The VA appraisal is not an inspection.

Step 9: If you have a 100% disability rating, apply for California's Disabled Veterans' Exemption

California offers a property tax exemption for the home of a veteran who is rated 100% disabled (or 100% due to unemployability) from a service-connected condition, is blind in both eyes, or has lost the use of two or more limbs, and to certain unmarried surviving spouses. For the 2026 lien date, the California State Board of Equalization set:

• Basic exemption: up to $180,671 of assessed value.
• Low-income exemption: up to $271,009, if household income is $81,131 or less.

At California's 1% base property tax rate, those exemptions are worth roughly $1,807 and $2,710 a year, respectively, before local voter-approved add-ons. The exemption replaces the homeowners' exemption, it can't exceed the assessed value, and it doesn't apply to special taxes or direct levies.

How to do it:

1. After closing, file form BOE-261-G with the San Diego County Assessor's office.
2. The basic exemption is a one-time filing. The low-income exemption must be filed every year.
3. Watch for a supplemental assessment notice after you buy, and file within the deadlines the county gives you.

Step 10: A sample timeline

Your VA buyer checklist

1. Certificate of Eligibility in hand, and entitlement understood
2. Funding fee status confirmed (exempt or not, first use or subsequent)
3. DTI at or under 41%, or residual income at least 20% above the guideline
4. Three Loan Estimates compared on the same day
5. Cash for closing costs, or a plan to ask for a seller credit within the 4% concession cap
6. Offer priced to support the VA appraisal
7. Independent home inspection scheduled
8. Property tax exemption filed after closing, if eligible

What this means day to day

For a San Diego family with a service member at one of the county's bases, or a veteran who's been renting since leaving the service, the VA loan can turn a home purchase from a decade of saving into something possible this year. But the payment on a median-priced home at today's rates, about $7,200 a month with taxes and insurance in our example, is serious money. The smartest VA buyers we work with know their entitlement before they shop, run the residual income test themselves, and use the softer market, with about one in five listings cut, to get the seller to help with closing costs.
