Co-Buying a Home Explained

How to successfully purchase a home with partners or friends

Co-buying—purchasing a home with friends, family, or partners—is becoming increasingly popular as home prices rise. Here's what you need to know to do it right.

1Why Consider Co-Buying?

Benefits of purchasing together:
  • Increased buying power: Combined incomes qualify for more
  • Shared costs: Split down payment, mortgage, and expenses
  • Build equity together: Both parties benefit from appreciation
  • Access better locations: Afford neighborhoods you couldn't alone
  • Shared maintenance: Divide home upkeep responsibilities

2Choosing the Right Co-Buyer

Not everyone makes a good co-buying partner:
Ideal partners have:
  • Similar financial habits and goals
  • Compatible living expectations
  • Good credit scores
  • Stable income
  • Clear communication style

Red flags:
  • History of financial irresponsibility
  • Different timelines for staying in the home
  • Incompatible lifestyles

3Legal Structures for Co-Ownership

Understand your options:
Tenants in Common (TIC):
  • Can own unequal shares
  • Can sell or transfer your share independently
  • Shares pass to heirs, not co-owner

Joint Tenancy:
  • Equal ownership shares
  • Right of survivorship (share goes to co-owner if you pass)
  • All owners must agree to sell

4The Co-Buying Agreement

Always get this in writing:
Your agreement should cover:
  • Ownership percentages
  • How expenses are divided
  • What happens if someone wants to sell
  • Process for buying out a partner
  • Rules for renting or modifications
  • Dispute resolution process

Pro Tips

  • Hire a real estate attorney to draft your co-buying agreement
  • Get pre-approved together to know your combined buying power
  • Discuss exit strategies before you buy
  • Use NestCost's Co-Buy feature to see combined affordability
