Can Buying a Home With Friends or Family Actually Work?

Imagine this: a house in your area costs $380,000. To buy it on your own, you'd need around $13,300 just for the down payment — and that's before closing costs, inspections, or the first few months of bills. For a lot of people I talk to, that number alone is enough to make them close the browser tab and go back to renting. I get it.

But lately, more and more of my clients are asking a different question: "What if I bought with my sister? Or my best friend? Could that actually work?" Honestly? It can. But like most things in life, it depends on how you do it.

Let me walk you through what co-buying really looks like — the real benefits, the real risks, and how to protect yourself if you go this route.

How Co-Buying Can Actually Solve the Affordability Problem

When two people buy together, the math changes fast. Let's use that same $380,000 home as an example:

• Solo buyer earning $65,000/year: Monthly payment around $2,400. That's likely too high for most lenders to approve comfortably.
• Two buyers each earning $65,000/year (combined $130,000): Now the DTI (debt-to-income ratio) gets much more manageable, and both incomes count toward qualification.

Down payment splits in half. Closing costs split in half. Monthly mortgage splits in half. For many families, this is the difference between buying now and waiting another 5 years.

Who Can Co-Buy a Home — And What Are the Loan Options?

You don't have to be married or even related. I've helped siblings buy together, parents and adult children, and yes — close friends. As long as everyone qualifies and agrees on the terms, lenders don't require a family relationship.

Some options that work well for co-borrowers:

• Conventional loans: Both borrowers' credit scores are evaluated — lenders typically use the lower middle score of the two. So if one person has a 720 and the other has a 660, expect to be priced based on the 660.
• FHA loans: Allow multiple non-married co-borrowers with as little as 3.5% down, which on a $380,000 home is about $13,300 split two ways — roughly $6,650 each.
• ITIN loans: If one borrower doesn't have a Social Security number, there are still options. I work with people in that situation regularly — it's more common than people think, and it's not a dealbreaker.

The Real Risks You Need to Know Before You Sign Anything

I'd be doing you a disservice if I only told you the good stuff. Co-buying has real risks, and here's what I always tell my clients:

• What happens if one person wants to sell and the other doesn't? This needs to be written down before closing — in a co-ownership agreement drafted by a real estate attorney.
• What if one person stops paying their share? The lender doesn't care about your arrangement — they care about the mortgage. A missed payment hurts both credit scores.
• How is ownership split? "Tenants in common" vs. "joint tenancy" affects what happens to the property if one owner passes away. Your attorney can explain both.

These aren't reasons to avoid co-buying — they're reasons to do it right.

One Document That Can Save the Whole Deal: The Co-Ownership Agreement

Before you close, work with an attorney to put together a written agreement that covers:

• Each person's ownership percentage
• How monthly costs are divided
• What happens if someone wants to exit
• How decisions about repairs or renovations get made

It typically costs $500–$1,500 to have this drafted properly. That's a small price to protect a $380,000 investment and a relationship.

Next Steps: Is Co-Buying Right for You?

Co-buying isn't for everyone — but for the right people, with the right setup, it's a genuinely smart way to get into homeownership without waiting another decade. The key is going in with clear expectations, legal protection, and a loan officer who understands your full picture.
