Fannie Mae Guidelines: Using Borrowed Funds Secured by Assets

What Are Borrowed Funds Secured by an Asset?

This guideline covers situations where you borrow money using something you own as collateral. Think of it as taking a loan against your car, your stock portfolio, your 401(k), or even a piece of art you own.

Fannie Mae treats this borrowed money as acceptable for your home purchase because you're essentially converting your existing equity into cash. You're not creating new debt out of thin air — you're liquidating value you already have.

Say you own $50,000 worth of stock but don't want to sell it. You could take a $30,000 loan against those stocks to use for your down payment. The stocks secure the loan, meaning the lender can take them if you don't repay.

Acceptable Assets for Collateral

You can use various assets to secure these loans. Financial assets work well: savings accounts, certificates of deposit, stocks, bonds, mutual funds, and retirement accounts like 401(k)s.

Physical assets also qualify. Your car, valuable artwork, collectibles, or real estate you own can all serve as collateral for these loans.

The key requirement is that you must actually own the asset. You can't use someone else's property or an asset you're still paying off as collateral.

How Secured Loans Affect Your Debt Ratios

When your lender calculates your debt-to-income ratio, they must include the monthly payment on any secured loan. This payment gets added to your other monthly debts like credit cards, car loans, and student loans.

If the secured loan doesn't require monthly payments — maybe it's a balloon loan due in full later — your lender must calculate what an equivalent monthly payment would be and count that amount as recurring debt.

There's one exception: if you secure the loan with financial assets like stocks or savings accounts, the monthly payment doesn't have to count as long-term debt. This gives you more flexibility in your debt ratios.

The Asset Reduction Rule

Here's where things get tricky. If you use the same asset both as loan collateral and as part of your financial reserves, Fannie Mae requires your lender to reduce the asset's value.

Say you have $100,000 in a savings account. You borrow $40,000 against it for your down payment, but you also want to count the remaining $60,000 as reserves. Your lender must reduce the account value by the $40,000 loan amount plus any related fees when calculating your reserves.

This prevents you from double-counting the same money. You can't claim the full $100,000 as reserves when $40,000 of it is tied up securing your loan.

Required Documentation

Your lender needs three key pieces of documentation for any secured loan. First, they need the complete loan terms — interest rate, payment schedule, maturity date, and collateral description.

Second, they must verify that the party providing the secured loan has no connection to your home purchase. The lender can't be your real estate agent, the seller, the builder, or anyone else involved in the transaction.

Third, they need proof that the borrowed funds actually transferred to you. Bank statements showing the deposit, wire transfer records, or cashier's check documentation all work.

Why Fannie Mae Allows This

Fannie Mae permits secured borrowing because it represents a return of your own equity, not new debt creation. When you borrow against assets you own, you're converting illiquid wealth into cash for your home purchase.

This differs from unsecured personal loans or credit card advances, which create new debt without underlying collateral. Secured loans have lower risk because the lender can recover their money by taking the collateral if you default.

The asset reduction rule exists to prevent borrowers from inflating their financial picture. Without this rule, you could make the same money appear twice in your loan application — once as an asset and again as borrowed funds.

Common Complications and Gotchas

The biggest mistake borrowers make is not understanding how secured loans affect their debt ratios. That $500 monthly payment on your stock-secured loan counts just like any other debt payment when your lender calculates whether you qualify.

Timing can also create problems. If you take the secured loan too close to closing, your lender may not have enough time to properly document everything. Start this process early in your home buying journey.

Some borrowers try to use assets they don't fully own as collateral. If you still owe money on your car or have a 401(k) loan outstanding, the available collateral value is reduced by what you owe.

Watch out for loans secured by retirement accounts. While these are allowed, they often come with restrictions and penalties that make them expensive sources of funds. Your 401(k) provider may limit how much you can borrow or charge high fees.

The "no connection to the sale" rule can trip up borrowers who try to get creative. Your mortgage broker can't also provide the secured loan. Neither can your real estate agent's lending company or the seller's business partner.
