Co-ownership Risk Calculator
How much are you risking without a plan?
When you buy a home with friends, family, or partners, you're exposed to financial risk. Many co-buyers don't realize until it's too late. Our free calculator analyzes court records and foreclosure data to show your potential dollar exposure across key risk areas:
- Payment disputes: 36% of households struggle with expense disagreements
- Forced sale/foreclosure: 27% average loss in foreclosure situations
- Legal battles: Common when no agreements exist
- Death/illness: 5-7% loss on rushed estate sales
- Relationship breakdown: Money issues strain relationships

How we calculate co-ownership risk
Our calculator uses California and Texas court records, as well as federal foreclosure data, to estimate potential financial exposure. Traditional co-ownership agreements can't handle real-life changes, leading to expensive legal battles or forced sales at below-market prices.
Most co-ownership groups have $300,000 or more in financial risk exposure that can be mitigated through planning, structuring, and management.

Questions & answers
Co-owners face risk across five main areas: payment disputes (research indicates roughly one in three co-owning households struggle with expense disagreements), forced sale or foreclosure (with average losses around 27% based on federal data), legal battles when no agreements exist, death or illness of a co-owner (5-7% loss on rushed estate sales), and relationship breakdown that triggers financial conflict.
The calculator uses California and Texas court records and federal foreclosure data to model potential dollar exposure. It applies documented loss percentages to your property value and divides exposure across your number of co-owners.
The most effective protection is a living Co-ownership Agreement backed by governance tools. Co-ownerOS™ from CoBuy simplifies agreements, dispute resolution frameworks, expense tracking, and exit planning for co-owner groups of 2-4 people at $500 per year.
94% of U.S. co-buyers say they need help with a Co-ownership Agreement, according to CoBuy's 2025 survey of 1,637 co-owners. Without one, co-owners face uncertainty in the case of death, job loss, change in relationship status, or financial hardship. Disputes typically default to state law, which often means expensive partition actions or forced sales at below-market prices.
Start with CoBuy Wizard to assess whether co-buying is a good fit for your specific group. Wizard surfaces alignment issues—like different exit timelines or usage expectations—that cause problems later. It's $250 per group and each person answers independently. Once you know co-buying makes sense, connect with CoBuy-certified™ Pros and use Co-ownerOS™ to structure your co-ownership before closing.
