Understanding Private Mortgage Insurance (PMI)

PMI is a lender’s safety net, not yours. It’s an additional cost added to your mortgage when your down payment is less than 20%, designed to protect the lender if you default. Understanding PMI is crucial to managing your homebuying budget effectively.

What is PMI?

Private Mortgage Insurance is a policy required by lenders on conventional loans when your down payment is below 20% of the home’s purchase price. It’s paid by you, the borrower, but benefits the lender by reducing their risk.

Purpose of PMI

Protects lenders from losses in case of foreclosure, enabling lower down payments (e.g., 3-10%) for buyers.

How PMI Works

PMI is typically calculated as a percentage of your loan amount and varies based on factors like credit score and loan-to-value (LTV) ratio:

PMI Cost Example

For a $300,000 home with a 10% down payment:

  • Loan Amount: $270,000
  • PMI Rate: 1% annually
  • Annual PMI: $2,700
  • Monthly PMI: $225
  • Total PMI (5 years): $13,500 (if equity takes 5 years to reach 20%)

PMI Across Loan Types

PMI rules differ depending on your mortgage:

Important

FHA MIP can’t be removed without refinancing to a conventional loan if your down payment is < 10%—plan ahead!

Strategies to Avoid or Eliminate PMI

You’re not stuck with PMI forever—here’s how to minimize or avoid it:

PMI Avoidance Checklist

1
Save for 20% Down

Avoid PMI entirely by putting 20% or more down (e.g., $60,000 on a $300,000 home).

2
Build Equity Faster

Pay extra toward principal or wait for home value appreciation to hit 20% equity, then request PMI removal.

3
Refinance Strategically

If your LTV drops below 80% due to rising home value, refinance to a conventional loan without PMI.

4
Piggyback Loan

Use an 80/10/10 loan (80% mortgage, 10% second loan, 10% down) to bypass PMI—compare interest costs.

!
Lender-Paid PMI (LPMI)

Lender covers PMI for a higher interest rate—crunch the numbers, as it may cost more long-term.

Pro Tip

Monitor your LTV ratio—request an appraisal if home values rise to cancel PMI sooner.
