What Are Trust Accounts in Mortgage Lending
Trust accounts hold money or assets managed by a trustee for your benefit. These arrangements come in many forms — family trusts, living trusts, investment trusts, or trusts created through inheritance or legal settlements.
The key question for mortgage purposes is whether you can actually access the money when you need it. Some trusts give you immediate access to funds. Others restrict when and how much you can withdraw. Still others only provide income distributions without touching the principal.
Say your grandmother left you a trust that holds $100,000 in investments. If the trust document says you can withdraw any amount at any time, those funds work for your mortgage. But if the trust only pays you monthly income and doesn't allow principal withdrawals until you turn 35, you can't use that $100,000 for your down payment.
How Lenders Verify Trust Account Funds
Your lender needs official documentation directly from the trust's management. This means getting a letter from either the trust manager (if it's a managed trust) or the trustee (the person or institution legally responsible for the trust).
The documentation must include the current value of your interest in the trust. This isn't always the same as the total trust value if you're one of multiple beneficiaries or if your access is limited to a percentage.
The letter also needs to spell out exactly how you can access the funds. Can you withdraw any amount at any time? Do you need trustee approval? Are there waiting periods or restrictions on how much you can take out in a given timeframe?
Your lender will want to see recent trust statements showing account activity and current balances. Bank statements from the trust's accounts may also be required to verify the funds actually exist and aren't just paper values.
Trust Income vs. Trust Principal
Fannie Mae treats trust funds differently depending on whether you're accessing the principal (the money in the account) or the income (earnings from investments held in the trust).
If you're using trust principal for your down payment or closing costs, the focus is on immediate access. The lender needs to confirm you can actually get the money when you need it for closing.
If you're also counting trust income toward your qualifying income, that gets analyzed separately under the trust income guidelines in [[B3-3.1-09]]. The lender needs to understand how withdrawing principal might affect future income distributions.
For example, if your trust holds $200,000 in dividend-paying stocks and generates $8,000 per year in income, withdrawing $40,000 for a down payment might reduce future income to $6,400 per year. Your lender needs to factor this into your qualifying ratios.
Why Fannie Mae Requires This Documentation
Trust accounts create unique risks that don't exist with regular bank accounts. The money might be tied up in investments that can't be quickly liquidated. Legal restrictions might prevent access even if the funds exist. Multiple parties might have claims on the same money.
Fannie Mae wants to ensure the funds are both available and legally accessible. A trust document that looks generous on paper might have hidden restrictions that prevent you from actually using the money for your home purchase.
The requirement for written documentation from the trust manager or trustee creates an official paper trail. This protects both you and the lender by confirming that all parties understand what funds are available and under what conditions.
Common Complications with Trust Accounts
Trust documents can be complex legal instruments with language that's difficult to interpret. Sometimes even the trustee isn't certain about withdrawal restrictions without consulting the trust's attorney.
Investment-based trusts present timing challenges. If the trust holds stocks, bonds, or real estate, converting those assets to cash for your closing might take weeks. Your lender needs to know this timeline upfront.
Family trusts sometimes have informal arrangements that don't match the written trust document. Maybe your parents always said you could access the money anytime, but the actual trust requires their approval for withdrawals over $10,000.
Revocable living trusts created for estate planning purposes usually give you full access to funds, but the documentation requirements are still the same. Even if it's technically "your" money, the lender needs official confirmation from the trustee.
Some trusts have "spendthrift" provisions designed to protect the money from creditors or poor financial decisions. These same provisions might restrict your ability to use trust funds for a home purchase, even if that seems like a reasonable use of the money.

Trust Accounts
Funds disbursed from a borrower’s trust account are an acceptable source for the down payment, closing costs, and reserves provided the borrower has immediate access to the funds.
To document trust account funds, the lender must:
obtain written documentation of the value of the trust account from either the trust manager or the trustee, and
document the conditions under which the borrower has access to the funds and the effect, if any, that the withdrawal of funds will have on trust income used in qualifying the borrower for the mortgage.
