Short answer
Often, yes. Fannie Mae accepts money borrowed against an asset you own, including your home, for the down payment, closing costs and reserves on a conventional loan, because it's a return of your own equity. The HELOC's monthly payment then counts as a debt when the lender qualifies you. DSCR lenders set their own rules, so ask each one.
What does Fannie Mae say about borrowed funds?
Fannie Mae's Selling Guide treats funds borrowed against an asset you own, such as real estate, a car or an investment account, as an acceptable source for the down payment, closing costs and reserves. Its reasoning: the money is a return of your own equity.
The loan you borrow against has to be secured by that asset. Unsecured money, such as a personal loan or a credit card advance, is a different matter.
How does the HELOC payment affect qualifying?
The lender counts the HELOC's monthly payment as a debt when it figures your debt-to-income ratio. If the line has no required payment yet, the lender calculates an equivalent payment and counts that instead. So the same draw that funds your down payment also raises your monthly debts, and both sides need to work.
What should I line up before I draw on a HELOC?
- Open the line well before you need it, since a HELOC takes time to set up
- Keep a paper trail: the HELOC statement and the transfer into the account you'll close from
- Ask how the new rental's rent will be counted; see investment property loans
- Check reserves too; see how much in reserves you need
The HELOC or cash-out refinance guide compares the two ways to tap your equity. Tom doesn't give tax or legal advice.
