Buyer Education | Bay Area Mortgage
If you're buying a home in San Jose or the greater Bay Area and you're not putting 20% down, there's a good chance someone has mentioned PMI to you. Maybe it came up in a pre-approval conversation, or you noticed it listed as an extra cost on a loan estimate. Private mortgage insurance can add several hundred dollars or more to your monthly payment — but it's not unavoidable, and it's not permanent. This post is my plain-language guide to what PMI actually is, when it applies, and the legitimate strategies Bay Area buyers use to minimize or eliminate it.
PMI stands for private mortgage insurance. Despite the name, it doesn't protect you — it protects your lender. If you were to default on your mortgage, PMI pays the lender for a portion of their loss.
Conventional loans (backed by Fannie Mae or Freddie Mac) require PMI when your down payment is less than 20% of the purchase price. The lender sees a lower down payment as higher risk, and PMI is the mechanism they use to offset it.
Note: FHA loans have their own version of mortgage insurance called MIP (mortgage insurance premium), which works differently and is beyond the scope of this post. We're focusing on conventional PMI here.
PMI is typically calculated as a percentage of your loan amount per year, and it varies based on your credit score, loan-to-value ratio, and lender. Generally, PMI runs between 0.5% and 1.5% of the loan amount annually.
In the Bay Area, where home prices routinely start at $1M and jumbo loans (above $832,750 in 2026) are common, this matters a lot:
Example: On a $1,200,000 loan at 1% PMI, that's $12,000 per year — or $1,000 per month added to your payment. Even at 0.5%, you're looking at $500/month. That's a real number that deserves a strategy.
PMI is typically added to your monthly mortgage payment and collected by your lender, who pays it to the private insurer. It shows up as a separate line item on your mortgage statement.
The most direct path. If your down payment is 20% or more of the purchase price, PMI is not required on a conventional loan. In the Bay Area, this can mean a down payment of $280,000–$400,000 or more on a typical purchase — which is why many buyers explore the other options below.
This is a popular strategy for Bay Area buyers who don't have 20% down but want to avoid PMI. You take a first mortgage for 80% of the purchase price, a second mortgage (HELOC or fixed home equity loan) for 10%, and you put 10% down. Because neither loan individually exceeds 80% LTV, PMI isn't triggered. The tradeoff is a second loan with its own interest rate and payment — but for many buyers, the math still favors this approach over paying PMI.
Some lenders offer to cover the PMI cost themselves in exchange for a slightly higher interest rate — this is called lender-paid PMI (LPMI). You get a cleaner monthly payment with no separate PMI line, but your rate (and total interest paid over time) is higher. This can make sense if you plan to sell or refinance within a few years, before the higher rate accumulates too much in extra interest.
If you're already paying PMI, it's not forever. Federal law (the Homeowners Protection Act) requires your lender to automatically cancel PMI once your loan balance drops to 78% of the original purchase price based on your scheduled payments. But you don't have to wait — you can request cancellation at 80% LTV. In the Bay Area, where appreciation has been strong, you may have reached 20% equity faster than expected through home value growth, not just paydown.
One thing Bay Area buyers often overlook is that home value appreciation counts toward equity. If you bought a home two or three years ago with 10% down, and values in your neighborhood have increased 15–20%, there's a real chance your current LTV is already at or near 80%. That means you may be able to cancel PMI much sooner than your amortization schedule suggests.
To do this, most lenders require a formal appraisal to verify current market value. The appraisal cost is typically $500–$800, but if it results in PMI cancellation, the savings pay for it in the first month.

Jumbo loans — those above the conforming loan limit of $832,750 in most markets for 2026 — operate differently. They're not backed by Fannie Mae or Freddie Mac, so traditional PMI doesn't apply. Jumbo lenders set their own requirements, and some require 20% down while others allow lower down payments without requiring PMI, depending on your credit profile and the lender's guidelines.
If you're shopping for a home in the $1M–$3M range in Santa Clara County, you're almost certainly in jumbo territory. That's my specialty — and the rules are more flexible than many buyers realize. Let's talk before you assume you need 20% down.
Does PMI build equity for me?
No. PMI premiums go directly to the insurer — they don't reduce your loan balance or build equity in any way. PMI is purely a cost, which is why minimizing or eliminating it is worth strategizing around.
Can I deduct PMI on my taxes?
PMI deductibility has varied over the years based on Congress. I'd recommend asking your CPA for current guidance — I can refer you to a great local one if needed, but I never give tax advice and neither should your lender.
What's the difference between PMI and MIP?
PMI applies to conventional loans. MIP (mortgage insurance premium) applies to FHA loans. They work differently: FHA MIP has its own rules for cancellation (or in some cases, no cancellation at all for the life of the loan depending on your down payment). If you're considering an FHA loan, let's talk through the full picture before you commit.
Can I put 10% down on a Bay Area home and avoid PMI entirely?
Yes — through a piggyback loan structure or by choosing lender-paid PMI. Both approaches have trade-offs, and the right one depends on your rate, timeline, and long-term plans. There's rarely a one-size-fits-all answer — which is exactly why these conversations are worth having before you make an offer.
