Freddie Mac Guidelines: Mortgage Insurance Premium Options

How Mortgage Insurance Premium Payment Works

When you put down less than 20% on a conventional loan, you'll pay mortgage insurance. Fannie Mae allows several ways to structure these payments, and understanding your options can save you money or improve your cash flow.

The most common approach is monthly premiums paid through your escrow account. Your lender collects the premium along with your property taxes and homeowners insurance, then pays the mortgage insurance company on your behalf. This spreads the cost over time but means you'll pay the premium for years.

You can also pay an annual premium. This means paying the first year's premium at closing, then having your lender collect and pay annual renewals from your escrow account. The upfront cost is higher, but annual premiums are often lower than monthly ones.

A single premium means paying the entire cost upfront at closing to cover the life of the loan. This eliminates ongoing monthly payments but requires significant cash at closing. For a $300,000 loan, a single premium might cost $6,000 to $9,000.

Split premiums combine an upfront payment with ongoing monthly payments. You might pay $2,000 at closing and then $150 per month. This reduces both your upfront cost and your monthly payment compared to other options.

Financing Your Mortgage Insurance Premium

Fannie Mae allows you to finance your mortgage insurance premium into your loan amount, but this comes with strict rules. The key restriction is that your gross loan-to-value ratio — meaning your loan amount including the financed premium — cannot exceed 95%.

Say you're buying a $400,000 home with a $380,000 loan (95% LTV). If your mortgage insurance premium is $7,600, financing it would create a $387,600 loan on a $400,000 home. That's a 96.9% gross LTV, which exceeds the 95% limit.

However, if you're using a Home Possible, HomeOne, or HeritageOne loan program, the gross LTV limit increases to 97%. Using the same example, your $387,600 loan would represent a 96.9% gross LTV, which would be acceptable under these programs.

The property must be your primary residence or a second home. Investment properties cannot use financed mortgage insurance premiums under Fannie Mae guidelines.

Required Documentation for Financed Premiums

When you finance your mortgage insurance premium, your lender needs specific documentation to prove compliance with Fannie Mae requirements. The mortgage insurance company must provide a "financed mortgage insurance premium endorsement" with your policy.

This endorsement guarantees that if you ever file a claim, the insurance company will adjust the claim calculation to reflect the proper coverage level based on your original loan amount without the financed premium. Without this endorsement, Fannie Mae won't purchase your loan.

Your lender will also need to document both your base LTV ratio (calculated without the financed premium) and your gross LTV ratio (calculated with the financed premium). Both ratios must meet Fannie Mae's requirements for your specific loan program.

Understanding Lender-Paid Mortgage Insurance

With lender-paid mortgage insurance, your lender pays the premium and builds the cost into your interest rate. This eliminates your monthly mortgage insurance payment but typically increases your rate by 0.125% to 0.375%.

For a $300,000 loan, lender-paid MI might increase your rate from 6.50% to 6.75%. This adds about $45 to your monthly payment but eliminates a $200 monthly mortgage insurance premium, saving you $155 per month.

The trade-off is that you cannot cancel lender-paid mortgage insurance like you can with borrower-paid coverage. The higher interest rate stays for the life of the loan unless you refinance. However, the interest portion is tax-deductible while mortgage insurance premiums may not be.

Fannie Mae requires lenders to maintain specific servicing spreads to ensure they can make the premium payments. For fixed-rate loans, the minimum servicing spread must be at least 0.250%, with the total spread not exceeding 0.500%.

Why These Rules Exist

Fannie Mae's mortgage insurance requirements protect both borrowers and investors. The 95% gross LTV limit on financed premiums prevents borrowers from taking on excessive debt relative to their home's value. If home values decline, borrowers with higher LTV ratios face greater risk of owing more than their home is worth.

The requirement for primary residences and second homes reflects the lower default risk of owner-occupied properties. Investment property owners are more likely to walk away from underwater mortgages, making mortgage insurance claims more frequent and expensive.

The financed premium endorsement ensures proper insurance coverage even when the premium is rolled into the loan amount. Without this protection, the insurance coverage might be inadequate if calculated on the inflated loan balance rather than the true property risk.

Common Complications and Gotchas

Financing your mortgage insurance premium can push you over loan limits in high-cost areas. Fannie Mae's conforming loan limits apply to your total loan amount including any financed premium. In 2024, the baseline conforming limit is $766,550, but it's higher in expensive markets.

If your loan amount plus financed premium exceeds these limits, you'll need a jumbo loan, which typically has higher rates and stricter requirements. Always calculate your total loan amount including the financed premium when checking loan limits.

Lender-paid mortgage insurance can complicate refinancing decisions. Since the premium cost is built into your rate, you cannot simply cancel the coverage when you reach 20% equity. You'll need to refinance to eliminate the cost, which means paying closing costs and potentially accepting a different rate environment.

Some borrowers mistakenly believe they can deduct lender-paid mortgage insurance premiums on their taxes. Only the interest portion of your payment is deductible — the embedded insurance cost is not separately deductible like borrower-paid premiums might be.

Be careful with split premium structures during refinancing. If you paid an upfront portion of a split premium and refinance early, you typically cannot recover the unused portion. This makes split premiums risky if you might refinance within a few years.
