Freddie Mac Guidelines: Second Home Mortgage Requirements

What Qualifies as a Second Home

Fannie Mae draws clear lines around what counts as a second home versus an investment property. The property must be a single-unit dwelling that you occupy for some portion of each year. More importantly, you must keep it available primarily for your personal use and enjoyment — meaning more than half the calendar year.

You can rent out your second home on a short-term basis, but there are strict limits. The property cannot be subject to rental pools or agreements that require you to rent it out. You also cannot give a management company control over occupancy or enter revenue-sharing arrangements with developers or other parties.

Say you buy a cabin in the mountains that you use for summer vacations and occasional winter ski trips. You rent it out through Airbnb for a few weeks during peak season to help cover costs. This arrangement works fine as long as you maintain primary control and the rental activity stays secondary to your personal use.

The property must be in a location that makes sense as a second home. A condo in downtown Manhattan could qualify, but a warehouse in an industrial district would not. The home must also be suitable for year-round occupancy, though there's an exception for seasonal properties if the appraiser can find comparable sales with similar limitations.

Property Count Limits and Credit Score Requirements

Fannie Mae caps the total number of financed properties you can own. Each borrower individually, and all borrowers collectively on the loan, cannot be obligated on more than 10 one-to-four-unit financed properties. This count includes your primary residence and the second home you're buying.

The 10-property limit covers any debt or obligation tied to residential real estate — mortgages, land contracts, or other financing arrangements. However, several property types don't count toward this limit: commercial real estate, multifamily properties with five or more units, timeshares, undeveloped land, and manufactured homes not titled as real property.

If you already own more than six financed properties, you'll need a minimum credit score of 720 to qualify for the second home loan. This higher threshold reflects the increased complexity and risk of managing multiple mortgage obligations.

Properties titled in your business name don't count toward the limit if you're not personally obligated on the debt. The same applies to properties held in trust where you serve as trustee but have no personal liability.

Down Payment and Reserve Requirements

Second home purchases have stricter funding requirements than primary residences. All money used for the down payment, closing costs, and required reserves must come from your personal funds or other approved borrower funds as defined in Fannie Mae guidelines [[5501.3]] and [[5501.4]].

You cannot use most gift funds for a second home purchase. The only gift exceptions are wedding or graduation gifts, gifts or grants from government agencies, and employer-assisted homeownership benefits. Pooled funds from multiple sources are also prohibited.

You must meet the standard reserve requirements outlined in [[5501.2]]. These reserves ensure you can handle mortgage payments if your income temporarily decreases or you face unexpected expenses on multiple properties.

Income and Debt Calculations

Fannie Mae treats second home financing differently when calculating your debt-to-income ratios. Your primary residence housing payment — not the second home payment — gets used for the housing expense-to-income ratio calculation. This approach recognizes that your primary residence represents your core housing obligation.

However, the second home's monthly payment absolutely counts toward your total debt-to-income ratio. The lender will include principal, interest, taxes, insurance, and any HOA fees when calculating this payment amount.

You cannot count rental income from the second home toward your qualifying income, even if you plan to rent it occasionally. This rule prevents borrowers from inflating their income projections with optimistic rental estimates.

Say you earn $8,000 monthly and your primary residence costs $2,000 per month. Your housing ratio would be 25% ($2,000 ÷ $8,000). If the second home payment adds another $1,800 monthly to your total debts, that full amount gets included in your debt-to-income calculation.

Builder and Developer Restrictions

For newly constructed second homes, you cannot have any affiliation with the builder, developer, or property seller. This means no ownership interest in these entities and no employment relationship with them. The restriction prevents potential conflicts of interest and ensures arm's-length transactions.

This rule applies specifically to new construction purchases. If you're buying a resale home that happens to be relatively new, these restrictions don't apply as long as you're dealing with an unrelated seller.

Required Documentation

Your lender will need Form 3890, the Multistate Second Home Rider, attached to your mortgage documents. This rider modifies the standard mortgage terms to reflect the second home's intended use and occupancy requirements.

You'll also need to provide documentation proving the property's intended use as a second home rather than an investment property. This might include utility bills, insurance policies, or other evidence showing your personal connection to the property and area.

The underwriter will verify that you meet all property count limits by reviewing your credit report and asset documentation. They'll also confirm that your funding sources comply with the restricted gift and pooled fund rules.

Credit Fees and Pricing

Second home mortgages carry additional credit fees beyond standard loan pricing. These fees reflect the higher risk profile associated with non-primary residence lending. The specific fee amounts depend on factors like loan-to-value ratio, credit score, and loan amount.

You'll find the current credit fee schedule in Exhibit 19 of the Fannie Mae guidelines. These fees get paid according to the credit fee provisions in Chapter 6303, typically at closing or through higher interest rates.

Common Complications

The personal use requirement creates the biggest compliance challenge. If you rent out the property too frequently or enter management agreements that limit your control, the loan could be reclassified as investment property financing with different terms and pricing.

Property count calculations can also trip up borrowers with complex real estate holdings. Make sure your lender accurately counts only the properties that fall under Fannie Mae's definition. Business-owned properties or those held in certain trust structures might not count toward your limit.

The funding restrictions eliminate many creative financing strategies common in investment property deals. You cannot use borrowed funds for your down payment or combine gifts from multiple family members to reach your target amount.
