Your questions, answered.

What is co-ownership?

Co-ownership is when two or more people who are not married to one another own a home together.

Friends, family members, or couples—or any combination—can own a home together.

Co-ownership is also called shared homeownership, fractional homeownership, or joint homeownership.

What is Shared Homeowner OS™?

Shared Homeowner OS™ is an app to help you plan, structure, and manage co-ownership together efficiently and effectively.

Shared Homeowner OS™ puts co-owners in control over the entire lifecycle:

Who is it for?

Shared Homeowner OS™ helps folks who own a home together:

- Friends
- Family members
- Unmarried couples
- Couples
- Combinations of the above

Today, we're setup to help those who:

1. Co-own a home in the U.S.
2. Co-own a home as a group of 2 to 4 total (excluding renters, kids, anyone not on Title)

We're working to expand our offering.

How much does it cost?

Shared Homeowner OS™ subscription:

$30.00 / person / month, paid annually
$22.50 / person / month, paid annually  (25% off during private beta and beta)

That’s less than the cost of one cappuccino a week to protect your relationships, investment, and home.

What is a beta?

A beta is when our app is opened up for more people to try. During this phase, we invite a larger group to use the app and tell us what they think. Your feedback helps us spot any issues and improve the app before its full release. It's a team effort to make the app the best it can be.

How do we get started?

Join the waitlist for our beta here.

Thanks to all our private beta participants! We'll notify private beta participants and folks on the waitlist (in that order) ahead of the beta launch.

"Before learning about CoBuy, we went to see a lawyer to learn about the legal logistics. We left his office feeling more confused and discouraged than when we went in.

CoBuy has helped us smartly consider our options in joint ownership. We have peace of mind knowing we’ve covered all our bases and have contingency plans for all the what-ifs life can throw your way.

Highly recommend!"
