CalHFA Conventional vs FHA 2026: HomeReady, PMI & DTI Rules

San Diego County buyers can compare assistance, mortgage insurance and monthly costs before choosing a first mortgage.

California affordability makes every part of a home payment matter. When you’re considering CalHFA, the choice between a conventional and FHA first mortgage can change your down payment, mortgage insurance and debt-to-income (DTI) calculation. The headline rate alone won’t tell you which option costs less over time.

I’ll walk through how the two structures work, what the 80% Area Median Income (AMI) test actually measures, and how the numbers look on a $580,000 San Diego home. The figures are examples, not a rate quote or guarantee of approval.

1. Program Structure: CalHFA Conventional (Fannie/Freddie) vs. CalHFA FHA

CalHFA Conventional uses a Fannie Mae HFA Preferred or Freddie Mac Home Possible first mortgage. At a 3% down payment, it can be paired with CalHFA MyHome subordinate assistance of 3%. That assistance is a second loan, not a grant, and its repayment terms should be reviewed before you count on it.

CalHFA FHA uses an FHA-insured first mortgage and can be paired with MyHome assistance of 3.5%. FHA’s minimum down payment is generally 3.5% for borrowers who meet program requirements. The FHA loan also carries upfront and annual mortgage insurance.

Here’s the basic distinction:

✔ Conventional: 3% down, conventional mortgage insurance when required, and PMI that may be cancellable when equity and payment-history rules are met.

✔ FHA: 3.5% down, a 1.75% upfront mortgage insurance premium (UFMIP) that is typically financed into the loan, plus annual MIP.

✔ MyHome assistance: Can help cover the required down payment, but it is subordinate financing. Confirm the lien amount, repayment terms and combined loan-to-value limit with the lender.

For the official program details, review CalHFA Conventional and CalHFA FHA. I’ve also put together a companion guide to CalHFA MyHome assistance and income limits.

Credit-score requirements aren’t a simple “conventional higher, FHA lower” rule. Under the 2026 CalHFA guidelines in this comparison, CalHFA Conventional generally requires at least 660 for borrowers at or below the applicable income threshold and 680 for higher-income borrowers. CalHFA FHA generally requires 640, with 660 for manual underwrites and manufactured housing. Your lender must check the current program rules and the full automated-underwriting result.

2. Income Caps & AMI Limits: The 80% Area Median Income Threshold

There are two separate income checks, and mixing them up can derail your plans.

The CalHFA county income cap applies to qualifying borrower income under the program. Effective June 30, 2026, the stated limits include $259,000 for San Diego County and $214,000 for Los Angeles County. Check the current CalHFA income-limit document for the county where you plan to buy.

The HomeReady 80% AMI test is different. It’s tied to the property’s census tract, not just the county. That threshold can differ by tract and household size, so a countywide estimate is not enough. Ask your lender to verify eligibility using Fannie Mae’s AMI Lookup Tool and the property address.

If your income is above the applicable 80% AMI threshold but still within CalHFA’s county cap, you may still qualify for CalHFA Conventional. You may simply be ineligible for HomeReady’s reduced mortgage-insurance coverage and low-income pricing. If your qualifying income exceeds the CalHFA county cap, you can’t use CalHFA Conventional or FHA subordinate assistance under these income-limit rules.

3. Private Mortgage Insurance (PMI) Cost Analysis: Reduced PMI vs. Permanent FHA MIP

At 97% loan-to-value (LTV), HomeReady reduced mortgage-insurance coverage is 25%, compared with up to 35% standard coverage for similar LTV financing. Less coverage can mean a lower PMI premium, but it does not create one guaranteed rate. The mortgage insurer prices PMI based on factors such as credit score, LTV and loan features.

For an illustration, a 0.38% annual MI rate would be calculated like this:

Loan amount × annual MI rate ÷ 12 = estimated monthly PMI

The conventional PMI advantage is that it can generally be cancelled after you meet applicable equity and payment-history requirements, typically around 20% to 22% equity. The exact route depends on the loan and the applicable rules, so confirm the cancellation process with your servicer.

FHA’s standard UFMIP is 1.75% of the base loan amount and is typically added to the balance. For most 30-year FHA loans with less than 5% down, annual MIP is 0.55%. When you put less than 10% down, that FHA MIP generally remains for the life of the loan. That’s the structural contrast: FHA MIP can persist, while conventional PMI may be cancelled.

Your credit score matters. A lower score can make conventional PMI more expensive, so don’t assume conventional is cheaper just because it has cancellable PMI. I recommend asking the lender to price both options side by side. For a related overview of the underlying decision, see FHA versus conventional financing with 3% down.

4. Worked Underwriting Example ($580,000 Purchase in San Diego / Orange County)

Here’s an example using a $580,000 purchase in San Diego County. It focuses on down payment and mortgage insurance, not the complete monthly housing payment.

CalHFA Conventional example

✔ Purchase price: $580,000

✔ 3% down payment: $580,000 × 3% = $17,400

✔ MyHome Conventional assistance example: $17,400, covering the down payment

✔ First mortgage: $580,000 − $17,400 = $562,600

The first mortgage plus the $17,400 subordinate loan equals $580,000, or 100% combined loan-to-value (CLTV) against the purchase price. Your lender must confirm the specific CLTV limit and program eligibility for the transaction.

Using the illustrative 0.38% annual MI rate:

($562,600 × 0.0038) ÷ 12 = about $178 per month

This is an example only. The actual PMI quote can differ, and cancellation requires meeting applicable requirements.

CalHFA FHA example

✔ 3.5% down payment: $580,000 × 3.5% = $20,300

✔ Base loan: $580,000 − $20,300 = $559,700

✔ UFMIP: $559,700 × 1.75% = $9,794.75, typically financed

✔ Total loan after financed UFMIP: $569,494.75

At the illustrative 0.55% annual MIP rate:

($569,494.75 × 0.0055) ÷ 12 = about $261 per month

In this example, conventional PMI is about $83 less per month and avoids adding about $9,795 of UFMIP to the FHA loan balance. But the conventional route requires meeting its income and credit rules. FHA may fit a borrower who needs more flexibility with credit qualification.

Also, $0 down-payment cash does not mean $0 cash to close. Earnest money, appraisal and inspection costs, prepaids, title and escrow charges may still require funds from you.

DTI is based on your overall monthly debts and qualifying income. CalHFA’s general DTI cap is 45%, with potential extension to 50% through automated underwriting approval and a qualifying credit score under program rules. Lower insurance costs and no financed FHA UFMIP can help the conventional payment, but taxes, homeowners insurance, any required mortgage insurance and other debts still count in the full calculation.

Conventional PMI and FHA MIP work differently, so compare the full monthly payment and loan balance.

Quick FAQ

Can conventional PMI be cancelled?
Often, yes, once you meet the applicable equity and payment-history requirements. Ask your lender or servicer what applies to your loan.

Can I use CalHFA if I’m above 80% AMI?
You may still qualify for CalHFA Conventional if your qualifying income is under the county cap. You may not qualify for HomeReady’s reduced MI coverage and pricing. The property-address AMI check controls.

Is FHA always easier to qualify for?
Not necessarily. CalHFA FHA generally has a lower minimum score than CalHFA Conventional in the guidelines described here, but approval also depends on income, debts, property, underwriting findings and program rules.

Step-by-Step Checklist: Determining If You Qualify for CalHFA Conventional

1. ✔ Confirm the lender is CalHFA-approved. CalHFA loans are offered through participating lenders, not directly to consumers.
2. ✔ Check the county income cap. Use the current CalHFA limit for the county where the home is located.
3. ✔ Verify the property’s AMI. Have the lender check the census tract using Fannie Mae’s AMI Lookup Tool to determine whether you meet the HomeReady 80% AMI test.
4. ✔ Review credit and automated underwriting. Confirm whether the applicable CalHFA score threshold is 660 or 680 and whether your file meets the DTI rules.
5. ✔ Get current MI pricing. Ask for a written conventional PMI quote and compare it with FHA MIP, including the financed UFMIP and estimated monthly payment.
6. ✔ Confirm assistance and CLTV. Review MyHome’s subordinate-lien terms, assistance amount and combined financing limit.
7. ✔ Complete education at the right time. CalHFA requires homebuyer education and counseling for first-time buyers. Accepted options include the eHome America eight-hour course with counseling follow-up or an approved live course through a HUD-approved agency or NeighborWorks organization. Confirm the certificate timing with your lender.

Program limits, MI rates and guidelines can change. Lenders may also apply their own overlays and minimum requirements, so confirm current terms with a CalHFA-approved lender before making a decision.

Bottom line: CalHFA Conventional may be attractive if you meet the relevant income and credit rules and value potentially cancellable PMI. CalHFA FHA may be worth comparing if its qualification path better fits your situation. I’d compare the full payment, upfront loan balance, assistance terms and expected time in the home before choosing.
