Shopping for a home in San Diego County and not sure which loan tier fits your budget? You are not alone. Loan limits shape your purchase power, down payment plan, and even how competitive your offer can be. In this guide, you will learn how conforming, FHA, VA, and jumbo tiers work in San Diego, how to estimate your likely tier, and the questions to ask at pre‑approval so you can shop with confidence. Let’s dive in.
What loan limits mean
Loan limits set the maximum loan amount for different mortgage programs. Conforming limits are set by the FHFA and define whether a loan is eligible for purchase by Fannie Mae or Freddie Mac. You can confirm the current San Diego County figure using the FHFA’s official Conforming Loan Limits map and lookup tool. FHA has its own county‑based limits, which you can verify using HUD’s FHA Mortgage Limits lookup.
These limits apply to the loan amount, not the purchase price. Your loan amount equals the price you pay minus your down payment. If your loan amount is at or below the conforming limit, you are in the conventional conforming tier. If it is above the conforming limit, you are in the jumbo tier.
VA buyers have a special nuance. With full VA entitlement, many borrowers are not constrained by county loan limits the same way, though individual lenders may set their own standards. If you have partial entitlement or an existing VA loan, talk to a VA‑approved lender to confirm how limits and down payment apply to you.
- Check conforming loan limits: Use the FHFA’s county lookup tool under Conforming Loan Limits Map.
- Check FHA mortgage limits: Use HUD’s FHA Mortgage Limits lookup by selecting California, San Diego County, and the unit count.
Know your tier in San Diego
To estimate your tier, follow a quick framework:
- Choose a realistic target price for your neighborhood.
- Decide your planned down payment.
- Compute loan amount = Purchase Price − Down Payment.
- Compare that loan amount to the current San Diego County conforming and FHA limits.
Two simple formulas can help:
- Required down payment to stay conforming: DP_required = Purchase Price − Conforming Limit.
- Max purchase price that stays conforming with a set down payment: P_max = Conforming Limit + Down Payment.
If you plan to use FHA, also confirm the FHA county limit for your unit type. VA borrowers should verify entitlement and any lender overlays before setting a price range.
How limits affect purchase power
Conforming vs. jumbo:
- Conforming loans often offer broader lender competition, more product options, and lower reserve needs.
- Jumbo loans usually require higher credit scores, larger reserves, and sometimes higher down payments, which can reduce purchase power even if you qualify on paper.
FHA vs. conventional:
- FHA allows low down payments and flexible credit, but includes upfront and annual mortgage insurance, which increases monthly cost.
- Conventional loans with less than 20% down require PMI, which affects your monthly payment and qualifying ratios.
VA:
- Eligible VA borrowers with full entitlement often can buy with zero down and no monthly mortgage insurance, which boosts purchase power.
- Lenders may still set standards that affect your maximum loan size.
Underwriting basics by tier
Credit score expectations (typical ranges):
- FHA: Program minimums generally 580+ for 3.5% down; many lenders prefer 620+.
- Conventional conforming: Often 620–640+ minimum; best pricing improves at higher scores.
- VA: No VA minimum score, but many lenders use 620–640+.
- Jumbo: Commonly 700–740+ for stronger pricing.
Down payment and LTV:
- FHA: As low as 3.5% down for qualifying borrowers.
- Conventional: Options exist as low as 3% down; PMI applies under 20%.
- VA: Often zero down for eligible borrowers.
- Jumbo: Many lenders prefer 10–20% down, with stricter documentation.
Reserves and DTI:
- Conforming: DTI commonly up to about 45% for qualified borrowers, depending on the program.
- FHA: Flexible DTI; some scenarios allow higher with compensating factors.
- Jumbo: Often 6–12 months of reserves and tighter DTI caps.
Property types and occupancy:
- Limits vary by unit count (1–4 units). Duplexes and triplexes have different caps.
- Owner‑occupancy rules apply to FHA and VA; many first‑time conventional programs also require occupancy.
San Diego planning tips
San Diego County spans a wide price range, from relatively more affordable pockets of Chula Vista and Bonita to higher‑priced coastal and certain inland neighborhoods. Many first‑time buyers who make a conventional‑style down payment may fit within conforming limits in mid‑priced areas. If you are targeting higher‑priced coastal zones, plan for jumbo underwriting standards and reserves.
Local lenders in our market often have strong jumbo product lines and unique overlays. Rates, reserve rules, and documentation can vary widely between banks, credit unions, and mortgage brokers. Self‑employed buyers may see more flexible portfolio or bank‑statement programs, often at higher cost.
There are down payment assistance options in the region and at the state level. These programs change often, and each has its own income, price, and loan‑type rules. Confirm current eligibility with the relevant county or city housing offices and the California Housing Finance Agency, and check that assistance aligns with your target loan type.
Pre‑approval game plan
Use this checklist to prepare for a smooth pre‑approval:
- Verify current limits: Check the FHFA conforming and HUD FHA lookup tools and note the unit count.
- Estimate price: Use trusted local data to set a realistic range for your neighborhood.
- Decide your down payment: Include savings and any assistance or gifts.
- Calculate your loan amount: Compare it to conforming and FHA limits.
- Evaluate fit: If over the conforming limit, explore jumbo options; VA borrowers confirm entitlement and lender standards.
- Shop lenders: Compare rates, reserve requirements, products, and fees between at least two or three lenders, including a local option.
- Secure a pre‑approval letter tailored to your likely loan tier.
Documents to gather:
- Photo ID and Social Security number
- Two years of W‑2s or full tax returns if self‑employed
- Two recent pay stubs
- Two months of bank statements (some jumbo lenders may ask for three)
- Asset and retirement statements, and gift letters if using gifted funds
- Brief letters explaining any credit issues
Smart questions to ask lenders:
- What conforming limit are you using for San Diego County today?
- Do you have overlays for FHA, VA, or jumbo?
- What minimum credit score and reserves do you require for the LTV I need?
- How does PMI cost change with higher down payment or better credit?
- For VA: How will my entitlement affect the need for a down payment?
- What is your typical underwriting and closing timeline in this market?
Cost‑saving strategies
- Increase your down payment to bring the loan amount under the conforming limit and access broader options and often better pricing.
- Consider 20% down on a conventional loan to remove PMI if the math works for your budget.
- Use FHA when its credit flexibility and low down payment outweigh the added MIP, and when the property and local FHA limit fit your plan.
- If you need jumbo, shop multiple lenders or a broker with access to several investors, and work on credit and reserves to improve pricing.
Common San Diego scenarios
- First‑time buyer in East Chula Vista: With a modest down payment, your loan amount may fall within conforming limits, giving you more lender choices and potentially simpler underwriting.
- Move‑up buyer near the coast: Higher list prices can push you into jumbo territory. Make a plan for reserves, documentation, and timing before you write an offer.
- VA buyer moving to Bonita: With full entitlement, you may not be constrained by county limits the same way, but confirm lender standards early so your pre‑approval reflects your true ceiling.
