Dave Ramsey warns: Buying a house with someone you’re not married to costs you $35,000 and your future

Kevin from Charlotte called The Ramsey Show with what sounded like a reasonable plan. He and his girlfriend wanted to buy a house. Her dad would gift them $35,000 for a down payment. They had been living together for one year. Marriage was on hold because she is training for the 2028 Olympics and a wedding felt like too much stress.

Dave Ramsey did not soften the blow. “It is absolutely relationally, legally, financially stupid to buy a house with someone you’re not married to. Her father willing to give her shacked-up boyfriend $35,000 and have no protection on where that money’s gonna go is idiotic. That’s just dumb.”

If you put your name on a deed and a mortgage with someone you are not married to, you have signed a binding business contract without any of the legal scaffolding that handles a breakup. A divorce has rules. A breakup between co-owners has lawyers, billable hours, and a forced sale.

The verdict: Ramsey is right, and the math is brutal

The advice is sound because the legal and financial mechanics of unmarried joint home ownership are stacked against you.

Start with the gift. When a parent gifts $35,000 to a married couple for a down payment, that money flows into marital property. If the marriage ends, equitable distribution laws in most states handle the split. When the same parent gifts that money to a daughter whose boyfriend is on the deed, the legal picture changes. Once those dollars hit a joint closing, they are commingled into a jointly titled asset. The daughter has no automatic claim to a larger share unless the couple signed a written cohabitation agreement before closing. Most couples do not.

Now picture the breakup. The house is titled as joint tenants with right of survivorship, the standard default. One person wants out. The other cannot afford to refinance into a solo mortgage. The options shrink fast:

1. Sell the house, split the proceeds 50/50 regardless of who put in the down payment, and eat the transaction costs (realtor commission, closing fees, potential capital gains exposure).
2. One partner buys the other out, which requires qualifying for a new mortgage alone and coming up with cash for the departing partner’s equity share.
3. File a partition action in civil court, which forces a sale through litigation. Legal fees can run into five figures, and the judge does not care who paid what.

On a $350,000 home with the $35,000 down payment, if the couple splits after two years and the house has barely appreciated, selling costs alone can wipe out the entire down payment. The girlfriend’s college savings and her father’s gift get split 50/50 with someone she is no longer dating.

The net-worth gap Ramsey cited

Ramsey backed the advice with population data. “35-year-old men that are married have 4 times the net worth of 35-year-old men that are shacked up. That’s the data.” By age 50, he claimed, cohabiting women have 14 times less net worth than married women, and cohabiting men have 5 times less money.

These figures reflect correlation rather than proven causation, but the mechanism is clear. Married couples pool finances, file taxes jointly, inherit without probate friction, and split legal risk through clear default rules. Cohabiting couples do none of this automatically. They also save less. The U.S. personal savings rate sits at 3.7%, down from 5.2% a year earlier. Households have less cushion to absorb the cost of a botched co-purchase.

The variable that flips the math

The single factor that determines whether unmarried co-ownership is survivable is whether you have a written, attorney-drafted cohabitation and property agreement signed before closing. Without one, state default rules apply, and those rules assume you are roommates, not partners.

With a properly drafted agreement, the down payment source is documented, the equity split is defined, exit triggers are spelled out, and a buyout formula exists. The girlfriend’s $35,000 gift gets protected as her separate contribution rather than disappearing into a 50/50 split.

Without that agreement, the house becomes a joint business with no operating contract. Housing starts are running at 1.47 million annualized, well inside healthy territory. The risk lies in the structure of the deal, not the market.

What to do before signing anything

1. If you are going to buy together while unmarried, hire a real estate attorney to draft a cohabitation property agreement that documents down payment sources, equity percentages, expense splits, and a buyout formula.
2. Title the property as tenants in common with specified percentages, not joint tenants with right of survivorship, so each person’s share matches their actual contribution.
3. Run the breakup scenario on paper before closing. Calculate how much equity each person would walk away with if you sold in year two, year five, and year ten.
4. If the gift is from one partner’s parent, have that parent’s attorney structure it as a gift to their child only, documented in writing, ideally held briefly in a separate account before being applied at closing.

Ramsey’s recommendation was simpler: “Call the preacher and I’d go get married Saturday. And I’d have a party after the Olympics.” If that is off the table, treat the purchase like the business deal it actually is. A deed is a contract. Sign it accordingly.
