Before you buy together

A co-ownership agreement between friends should cover these key scenarios before emotions run high:

  • Β·What happens if one person wants to sell
  • Β·How buyout price is determined (appraised value vs. agreed formula)
  • Β·What happens if one person can't pay their share
  • Β·How maintenance and renovation decisions are made
  • Β·Right of first refusal if one owner sells their share

How buying a house with a friend works

Lenders treat friends the same as any co-borrowers. Both of you apply on one loan, both incomes and debts are combined, and both of you are fully responsible for the entire payment, not just your half. That is why the agreement between you matters as much as the loan.

QuestionTypical answer
Whose income counts?Both. Combined income raises the price you can afford.
Whose credit score is used?Lenders look at both scores. A lower score can raise your rate, so check with your lender before you apply.
Who is on the title?Usually both, as tenants in common, which allows unequal ownership shares.
Who is liable if one stops paying?Both. The lender can collect the full payment from either borrower.
How do we split costs?By ownership percentage, or equally. Write down which.

Tenants in common vs. joint tenancy

Most friends choose tenants in common. Each owner holds a defined share, which can be unequal, and each can leave their share to anyone. Joint tenancy means equal shares and automatic survivorship, so if one owner dies the other inherits. That is simpler, but it is usually a poor fit for friends who have different families. Ask a local real estate attorney which form your state recognizes.

Next steps

Run both incomes through the DTI calculator and the affordability calculator, estimate cash needed with the closing costs calculator, and if you plan to rent out a room, see the house hacking calculator. Couples who are not married can also read our unmarried couple guide.
