FAQs
Your questions, answered.
Co-ownerOS™ is built for 2–4 people buying or owning a U.S. residential property (up to four units). Friends, couples, or family can use it to align budgets, create agreements, track milestones, and manage ownership together — without scattered files or unclear responsibilities.
It’s a guided workspace for co-buyers and co-owners. You can:
• Plan budgets and draft legal agreements in under an hour
• Track property events in the shared Calendar (New)
• Manage decisions and edit terms anytime
• Store documents securely in the Vault
No scattered files or guesswork — just one platform for the full lifecycle, from planning to ownership to exit.
The Co-ownerOS™ Annual Pass costs $400/year total for up to 4 people. Introductory offer saves you $200 and ends Friday, August 22 at 11:59 pm PT.
A shared calendar that keeps you coordinated from buying through ownership. Track mortgage payments, insurance renewals, inspections, maintenance, and milestones. Set reminder presets, link events to documents in your Vault, and reduce missed deadlines that create disputes.
Yes. Every subscription includes ID verification, blockchain-anchored contracts, and encrypted storage. Only you and your co-owners can access your data. We apply the same encryption standards used by banks, so your agreements and documents stay private, tamper-resistant, and protected end-to-end.
Many complete governance and sign agreements in about 45 minutes. Others spread steps over a few sessions. Progress saves automatically, so you can work at your own pace.
Perfect — Co-ownerOS™ was designed for co-buyers too. Track pre-approval milestones, align budgets, generate agreements before closing, and then seamlessly transition into ownership management once you move in.
Absolutely. Co-ownerOS™ supports you through the full co-ownership lifecycle—from idea stage to exit.
Your Co-ownership Agreement includes exit procedures for buyouts, sales, or transfers. Co-ownerOS™ documents transitions and updates agreements automatically, so there are no surprises and relationships stay protected.
Any U.S. residential property: single-family homes, condos, duplexes, triplexes, or fourplexes. Not built for commercial property or groups larger than 4.
No. CoBuy generates customized agreements but isn’t legal advice. For complex scenarios — trusts, commercial property, or more than 4 owners — we recommend having an attorney review. Some groups still choose to get legal review even though setup can be done entirely in the platform.
