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.

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

"CoBuy was most helpful in ironing out the details and helping us ask questions we might not have asked. To have a structured agreement is great."

"Here are people who know how it works. I feel like our investment is protected and know that if something should happen, we have a plan in place."

Unmarried Couple Co-owners

CoBuy customer Genya talking about co-owning a home with her partner and their family members.
"We had a lot of what-ifs. Each of our parents are [financially] involved as well. The big things for us: to make sure everyone is on the same page and feels secure in their investment.

Having a step-by-step process helps, especially with the nitty gritty. It makes things feel feasible and reasonable.

Now it’s like ‘if that happens, we've already got this plan in place’.

I would absolutely recommend CoBuy!"
