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.

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

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.

Our co-owners say it best

"They called out things we had not thought of and helped us craft an operating agreement. I could not imagine going through this without CoBuy."

Peggy, Terry, Ray

Friend Co-owners

"CoBuy worked with us to navigate a system not built for communal home ownership. CoBuy is amazing, I would highly recommend."

Skyler & friends

Friend Co-owners

Friends, co-owners, and CoBuy customers, Amber & Nate.
"You want to know that you're taking care of yourself and your co-owner.

What things should we talk through? What are all of the risk factors? What are the exit strategies? What levers can you pull along the way? The potential for either of us to get into a long term committed relationship could complicate the situation.

CoBuy makes it easy. 100% recommend."
