CoBuyer success stories

"Our questions were around how is this going to work? What will it actually look like? And is there any liability?
Having that step-by-step process was great."

"I didn't really know where to start because we had different financial situations. How would that work out?
CoBuy walks you through the process. I would recommend CoBuy to anyone looking to buy a home together."

"Now we live in an awesome house with a mother-in-law apartment for my equally awesome mom!
We have peace of mind knowing that we've covered all our legal bases and have contingency plans for all the what-ifs that life can throw your way."

"We didn't know how long it was going to take or what the process was going to be like not being married.
We wanted to do it intelligently and safely for both of us.
It was nice to have somebody to help guide us. CoBuy was great!"

Friends, relatives, or partners planning to co-buy or who already co-own a U.S. residential property (up to four units) and want clear agreements plus shared finance tools.
Great—Co-ownerOS™ was built for co-buyers.
Align budgets and safeguards before you make an offer, generate an agreement ready for digital signatures at closing, and stay on a single platform from first brainstorm through exit strategy.
Absolutely. Co-ownerOS™ supports you through the full co-ownership lifecycle—from idea stage to exit.
Many groups finish the workflow, review, and digitally-sign in 45 minutes. Others spend a few weeks.
It's really up to you.
You can spread steps over as many sessions as you like—progress is saved automatically.
Any U.S. residential property with one to four units (single-family, condo, duplex, triplex, fourplex).
We don't support commercial properties or larger groups yet.
CoBuy is not a law firm and Co-ownerOS™ is not legal advice. The platform guides you through governance choices, generates a customized Co-ownership Agreement, and keeps everyone synced, but you can still hire an attorney to review or tailor the agreement if you wish.
For complex scenarios—commercial property, trusts, or more than four owners—we're not your solution; we recommend professional counsel.
