I've watched best friends become bitter enemies. Siblings sue each other into bankruptcy. Unmarried couples lose everything.

After 46,500 hours helping people co-buy homes, we've seen every possible disaster. The average loss? $350,000.

Here's the brutal truth about buying property with people you love.

First, The Psychology That Kills Every Deal

Two best friends buy a duplex. They've known each other 15 years.

What they don't see: confirmation bias is already destroying them. They ignore that one avoids conflict while the other thrives on it. They dismiss the 2x salary difference. They assume friendship conquers all.

18 months later: $75,000 in legal fees. Friendship: dead. House: forced sale.

This happens every. single. week.

The Disasters That Destroy Co-Owners

1. Someone Dies Without Papers ($75,000)

Seattle couple. Unmarried. She dies cycling to work. No will. No right of survivorship. His family claims half the house. 9-month probate. He can't pay the mortgage alone. Forced sale. Loss: $75,000 + home.

2. The Breakup Bloodbath ($100,000)

Three polyamorous tech workers buy together in Portland. Relationship implodes in 8 months. Nobody can afford to buy the others out. Lawyers get involved. 18 months of litigation. Forced sale in down market. Each person's loss: $100,000.

3. Job Loss Cascade ($50,000)

Four friends in Austin. Equal 25% ownership. One loses their job, can't pay. Others cover for 3 months. Then another loses their job. Now two people carry four people's mortgage. Credit scores destroyed. Foreclosure initiated. Total group loss: $50,000.

4. The "Minor" Repair War ($25,000)

Brother and sister inherit parents' house. Roof starts leaking. Brother: "Just patch it." Sister: "Full replacement needed." Three months of arguing. Water damage spreads. Mold develops. Final repair cost: $25,000. Relationship: dead.

5. The IRS Surprise ($50,000)

Friends contribute unequally but split ownership 50/50. IRS: "That's a gift." Surprise tax bill: $35,000. Plus penalties. Plus accountant fees to fix it. Total: $50,000. Nobody knew this was possible.

Why Traditional Solutions Fail

Static legal documents: That $10,000 attorney-drafted agreement becomes obsolete the moment life changes. New job? New partner? New financial situation? Too bad - you'll need another $10,000 to update it.

DIY templates: Downloaded templates miss critical state-specific requirements and relationship dynamics. They're like using a bicycle helmet for skydiving.

Verbal agreements: "We're friends, we'll figure it out" has destroyed more wealth than any market crash.

The Hidden Costs Nobody Calculates

  • Time sink: 120+ hours annually managing shared finances and decisions
  • Opportunity cost: Frozen equity when you can't agree on refinancing
  • Relationships: generally the first casualty of co-ownership disputes
  • Credit impact: One person's financial crisis becomes everyone's credit nightmare

Protect Your Group Now

Here's What Actually Works

Look, I'm not here to scare you out of co-buying. 30% of home purchases involve multiple non-married buyers. It works when done right.

Winners do five things losers don't:

  1. Everything in writing, updateable - Life changes. Your agreements must too.
  2. Exit before entry - Plan the breakup during the honeymoon
  3. Money firewalls - One person's crisis can't sink everyone
  4. Decision rules - Who decides what, when, how
  5. Quarterly reviews - Small issues before big disasters

The Truth Nobody Wants to Hear

You're not buying a home. You're launching a multi-party investment vehicle with your biggest asset and closest relationships at stake.

Your cute duplex? It's now a $910,000 business partnership with your best friend who has different risk tolerance, financial goals, and life timeline than you.

That $10,000 attorney-drafted agreement? It's obsolete the second someone gets married, divorced, pregnant, fired, or dead.

Those template documents? They're written by people who've never seen a co-ownership implode.

Your Three Options

Option 1: Wing it - Hope you're not the next disaster story I tell

Option 2: Traditional legal - Drop $10,000 on documents that can't evolve

Option 3: Built-for-purpose tools - Systems designed for how co-ownership actually works

We spent 10 years building option 3 because we got tired of watching people lose everything (and we struggled ourselves).
