What Is an FHA Loan?
An FHA loan is a mortgage insured by the Federal Housing Administration, a division of the U.S. Department of Housing and Urban Development (HUD). The FHA doesn't lend the money directly. Banks and mortgage companies do. But the FHA insures the loan, which means if you default, the FHA pays the lender.
This insurance backing allows lenders to be more flexible with credit scores and down payments. In expensive markets like San Francisco and Alameda County, where median home prices exceed $1.2 million, FHA loans make homeownership accessible to borrowers who might not qualify for conventional financing.
FHA Loan Limits in the Bay Area (2026)
FHA loan limits vary by county and household size. For 2026, the standard loan limit (the FHA floor for most of the country) is $541,287 for a single-family home, which is 65% of the $832,750 conforming baseline. However, California counties with high median home prices get higher limits.
Bay Area FHA Loan Limits
| County | Single-Family Limit | Median Home Price (2026) |
|---|---|---|
| Alameda County | $1,249,125 | ~$1,200,000 |
| San Francisco County | $1,249,125 | ~$1,300,000 |
| Contra Costa County | $1,249,125 | ~$1,100,000 |
| Santa Clara County | $1,249,125 | ~$1,500,000 |
These are "high-cost area" limits that allow FHA loans up to $1,249,125 in San Francisco and Alameda counties (2026 FHFA/HUD high-cost ceiling). Without these higher limits, Bay Area first-time buyers would be priced out of FHA financing entirely.
FHA Loan Requirements
1. Credit Score
- Minimum score: 500-580 depending on down payment and lender
- Best terms: 620+ credit score
- Most common approval: 580+ with 3.5% down
FHA's flexibility with credit scores is a major advantage for first-time buyers. You don't need perfect credit to qualify. However, if your score is below 620, lenders may require compensating factors: strong income, low debt-to-income ratio, significant savings, or other positive indicators.
2. Down Payment
- Minimum: 3.5% with credit score 580+
- Lower scores (500-579): May require 10% down
- Maximum allowed: Technically no limit, but most borrowers do 3.5-10%
For a $600,000 home in Alameda County, 3.5% down = $21,000. This is significantly less than conventional loans, which typically require 5-20% down. This is FHA's biggest advantage for savers with limited funds.
3. Debt-to-Income Ratio (DTI)
- Front-end (housing costs only): Up to 31% (compared to 28% for conventional)
- Back-end (all debts): Up to 43-50% (depending on compensating factors)
FHA allows slightly higher DTI ratios than conventional loans. This means if you have existing student loans, car payments, or credit card debt, FHA may still qualify you when conventional loans won't.
4. Employment & Income Documentation
- Most recent 2 months of pay stubs
- 2 years of W-2s or 1099s
- 2 years of tax returns (with schedules if self-employed)
- Employment verification letter from employer
- Written explanation for any employment gaps over 30 days
Self-employed borrowers need additional documentation: business tax returns, P&L statements, and sometimes business license verification. FHA will average your income over 2 years if it's variable or seasonal.
5. Property Requirements
- Must be your primary residence
- FHA appraiser must inspect and approve the property
- Property must meet safety, soundness, and sanitary standards
- No major structural defects
FHA appraisals are stricter than conventional appraisals. Properties must meet specific code and safety standards. In the Bay Area, where older homes are common, some properties may fail FHA appraisal due to deferred maintenance, outdated electrical systems, or lead-based paint issues. Work with an inspector familiar with FHA standards if you're concerned.
FHA Mortgage Insurance: The Real Cost
The biggest ongoing cost of FHA loans is mortgage insurance (MIP). This is the trade-off for the lower down payment and credit score flexibility. Understanding MIP is crucial to deciding if FHA is right for you.
Upfront Mortgage Insurance Premium (UFMIP)
When you close, you'll pay an upfront MIP (UFMIP) of 1.75% of your loan amount. This is typically rolled into your loan (meaning you finance it), rather than paying it out-of-pocket at closing.
Example: $600,000 home with 3.5% down in San Francisco
Loan amount: $579,000
UFMIP (1.75%): $10,133
New loan total: $589,133
You don't pay this $10,133 out-of-pocket. It gets rolled into your mortgage. But you end up financing it, so you pay interest on it over 30 years.
Annual Mortgage Insurance Premium (Annual MIP)
You'll also pay annual MIP, deducted from your monthly mortgage payment. The rate depends on your loan-to-value (LTV) ratio and loan amount.
| Down Payment | LTV | Annual MIP Rate | Example (on $600K home) |
|---|---|---|---|
| 3.5% down | 96.5% LTV | 0.55% | ~$3,185/year |
| 5% down | 95% LTV | 0.50% | ~$2,850/year |
| 10% down | 90% LTV | 0.50% | ~$2,700/year |
Bay Area note: on base loan amounts above $726,200, HUD steps the annual rate up to 0.70% (5% or 10% down) and 0.75% (3.5% down). Source: HUD Mortgagee Letter 2023-05.
When Does MIP End?
This is critical: If you put down less than 10%, MIP lasts the entire 30-year life of the loan. If you put down 10% or more, MIP ends after 11 years of payments (or when you refinance/pay off the loan).
This is a major difference between FHA and conventional loans. A conventional loan with 10% down can have PMI removed after reaching 20% equity. An FHA loan with 3.5% down keeps MIP for 30 years, unless you refinance into a conventional loan.
Total Cost Comparison: FHA vs. Conventional
Let's compare the true cost of FHA vs. conventional financing for a realistic Bay Area scenario.
Hypothetical rates to show the math, not an offer or a quote. Figures are interest rate only, not APR; APR includes loan costs and would be higher. Ask for today’s rate and APR.
Scenario: $600,000 Purchase in Alameda County
Option A: FHA Loan, 3.5% Down ($21,000)
- Base loan amount: $579,000
- Upfront MIP (1.75%): $10,133, rolled into the loan, so you finance $589,133
- Interest rate (assume 6.5%): $3,724/month P&I on $589,133
- Property tax (0.76%): $380/month
- Insurance: $200/month
- Annual MIP (0.55% of $579,000): $3,185/year ($265/month)
- Total monthly payment: $4,569
Option B: Conventional Loan, 5% Down ($30,000)
- Loan amount: $570,000
- Interest rate (assume 6.25%, slightly better): $3,510/month P&I
- Property tax (0.76% of $600,000): $380/month
- Insurance: $200/month
- PMI (0.5-0.7% of $570,000): $238-$333/month
- Total monthly payment: $4,328-$4,423
Option C: Conventional Loan, 20% Down ($120,000)
- Loan amount: $480,000
- Interest rate (6.25%): $2,955/month P&I
- Property tax (0.76% of $600,000): $380/month
- Insurance: $200/month
- PMI: $0
- Total monthly payment: $3,535
Analysis: FHA costs $200-300 more per month than conventional (5% down) in the short term, but that gap narrows as you build equity. Over 30 years, you'll pay $70,000+ more in MIP with the FHA 3.5% down loan than conventional PMI + 5% down. However, FHA lets you start with only $21,000 down versus $30,000, which matters if cash is tight.
Pros and Cons of FHA Loans
Pros
- Low down payment (3.5%): Makes homeownership accessible with minimal savings
- Lower credit requirements (580+): Qualify even with less-than-perfect credit
- Higher DTI allowance: Can afford more home if you have existing debt
- Flexible employment history: Can qualify with recent job changes if income is stable
- No maximum loan amount (within limits): Bay Area limits allow up to $1.15M
Cons
- Mortgage insurance lasts 30 years: If you put down 3.5%, you pay MIP forever (unless you refinance)
- Upfront insurance cost (1.75%): Increases your loan balance and interest paid
- Lower interest rates elsewhere: Conventional rates may be 0.25-0.75% better if you have good credit
- Strict appraisal standards: Property must pass FHA inspection; older homes may not qualify
- Less flexibility on loan terms: FHA is more rigid than some portfolio loans
Is FHA Right for You?
FHA is a good choice if:
- Your credit score is below 620
- You can only save 3.5-5% for a down payment
- You have significant existing debt (car loans, student loans) that increases your DTI
- You plan to buy and stay in your home long-term (so MIP duration is acceptable)
- You're a first-time buyer with limited resources
Conventional (possibly with CalHFA assistance) is often better if:
- Your credit score is 640+
- You can save 5-10% down (especially with CalHFA assistance bringing it to 0-3%)
- You have low existing debt (low back-end DTI)
- You plan to eventually pay down to 20% equity and remove PMI
- You want better interest rates and more long-term flexibility
FHA is not "bad." It's a valuable tool for Bay Area first-time buyers with limited down payment funds and lower credit scores. But mortgage insurance costs add up over time. If you can improve your credit or save more for a down payment, conventional + CalHFA assistance often results in lower lifetime costs. I'll run both scenarios for you to show which is better for your specific situation.
FHA Loans & CalHFA: A Powerful Combination
Did you know you can combine FHA financing with CalHFA down payment assistance? This is powerful in the Bay Area:
- FHA 3.5% down + CalHFA assistance: Potentially 0% out-of-pocket down payment
- FHA mortgage insurance: Allows lower credit scores
- CalHFA second mortgage: Interest-free or low-interest for 30 years
If you're a first-time buyer in Alameda or San Francisco with lower credit or savings, combining FHA and CalHFA may be your best path to homeownership.
Frequently Asked Questions
What are the FHA loan limits in San Francisco and Alameda County? +
For 2026, FHA loan limits in both San Francisco and Alameda counties are $1,249,125 for a single-family home. These high-cost area limits allow FHA financing for homes up to this price, making FHA viable in our expensive Bay Area market. Conforming loans (conventional) also follow these same limits.
What is mortgage insurance (MIP) and how much does it cost? +
MIP protects the lender if you default. You pay upfront MIP (1.75% of loan amount) at closing, usually rolled into the loan. You also pay annual MIP (0.50%-0.55% on loans up to $726,200, 0.70%-0.75% above that) as part of your monthly payment. For a $600K FHA loan, expect $10,500 upfront and $3,000-$3,300 annually in MIP costs.
How long do I have to pay FHA mortgage insurance? +
If you put down 10%+, MIP drops off after 11 years. If you put down 3.5% (the minimum), MIP lasts the full 30 years of the loan. This is a critical difference from conventional loans. Knowing this helps you decide whether FHA is right for you long-term.
What credit score do I need for an FHA loan? +
Minimum FHA credit score is 500-580 depending on down payment. With 580+, you can get 3.5% down. Most lenders prefer 620+ for faster approval and better terms. If your score is below 620, be prepared to show compensating factors: strong income, low debt, significant savings, or other positive indicators.
Can I use FHA and CalHFA together in California? +
Yes! You can use FHA financing with CalHFA down payment assistance. This allows first-time buyers to potentially put 0% down: FHA covers the mortgage, CalHFA covers the down payment. This combination is powerful for first-time buyers in Alameda and San Francisco with limited savings. Ask me if you qualify.
