Should my parents co-sign my mortgage?
Only if income is the thing stopping you. A co-signer adds their income to your application, so it can close the gap between what you earn and what the payment costs. It does nothing about a shortage of cash to close. And your parent takes on the whole loan without owning any part of the house.
Find out which of those two is short on your file before anyone signs. There’s often a smaller ask that moves your number further.
What Does a Co-Signer Agree To?
The whole loan, and none of the house. A co-signer signs the promissory note and owes every dollar of the debt, without going on the deed, under Fannie Mae’s guide section B2-2-04. A non-occupant co-borrower takes the same liability and can be on the deed. The two roles differ in ownership, not in what they owe.
So your parent takes on four things:
- Legal responsibility for the full payment, from day one
- A late mark on their credit if the loan goes delinquent
- A mortgage that counts in their debt ratio the next time they borrow
- A house that counts toward the number of properties they’ve financed
That third one is the part most buyers never hear. A lender can leave your housing payment out of your parents’ ratios, but only on conditions. Your parents have to be obligated on the mortgage. No payment can have been late in the last twelve months. And the file needs a year of canceled checks showing you made them. That’s Fannie Mae B3-6-05. Until that year exists on paper, your whole payment counts against them.
And there’s no release form. Your parent comes off when the loan is refinanced in your name alone, or when the house sells.
Will a Co-Signer Fix What’s Stopping You?
Only if your income is what’s short. Buyers get stuck on one of two things. Either the payment doesn’t fit your income once your other debts count against it, or you don’t have the cash to close. A co-signer moves the first and leaves the second alone.
Adding a parent tightens one rule while it loosens another. With a non-occupant on the loan, automated underwriting caps the mortgage at 95 percent of the home’s value. A file that goes to manual underwriting has to fit a 43 percent debt ratio on the buyer’s income alone, with a 90 percent cap. FHA holds a non-occupying borrower to 75 percent, and raises it to as much as 96.5 percent when the borrowers are family, under section II.A.2.b of HUD Handbook 4000.1.
One question settles which wall you’re hitting, and you can ask whoever quotes you. On my file, what’s short, the income or the cash to close? If it’s the income, ask what your own monthly debts do to that ratio first, student loans included.
Is There a Smaller Thing to Ask For?
Money aimed at your own debt usually does more than a signature. An installment debt that’s paid off, or paid down to ten or fewer remaining payments, doesn’t have to count in your long-term debt, per Fannie Mae B3-6-07. Freed-up income is what a loan amount gets built from, so clearing a car payment can raise what you qualify for without adding anyone to your note.
Three limits come with that. A lender can still count a nearly-finished debt if it would affect your ability to pay. A lease counts no matter how many payments are left, so paying one down accomplishes nothing. And closing out a paid-off account can move a credit score in either direction, so the timing deserves a conversation before the money moves.
The clean way is for your parents to pay the creditor directly, before your application goes in, so the account reports as paid. Your broker confirms how a given lender wants that documented. If your parents want to see that arithmetic for themselves, the case for paying off the car first is written to them. And co-signing is still the right tool when there’s no debt to clear and your income doesn’t reach the payment on the house you need.
Buyers ask how long a co-signer has to stay on, as if a term runs out. None does, so settle the exit before anyone signs. Agree on what has to be true for you to refinance on your own income, and roughly when. Nobody can promise a date. Everybody can agree on the plan.
