Free, no sign-up, useful whether or not you ever use our software. Built for families who inherited a place together and now have to work out how to share it.

Sibling buyout calculator
Open →What it costs to buy a co-owner out, and what that person would actually net if the place were sold instead. The two numbers are usually closer than anyone expects, and knowing which is larger changes the conversation.
Expense split calculator
Open →Equal shares, by usage, or the hybrid most cabin agreements actually use. Includes credit for the person who does the work, and works out who pays whom at the end of the year.
Fair scheduling, four ways
Open →First come, rotation, snake draft, or a points budget, applied to the same summer and the same families. The three-year view is the one that ends the argument.
In the order we are building them.
These are free to link to or hand to a client, with no attribution required and nothing to sign up for. If you draft cabin trusts, family LLCs or co-ownership agreements and would find a co-brandable version of the agreement template useful, we would rather build what you would actually use than guess.
The gap we keep hearing about is not the drafting. It is that a family signs a good agreement and then has no practical way to operate it, so within three years they are back to a group text and a spreadsheet.
One person chases the plumber, keeps the calendar in their head, and works out what everyone owes. Heirloom is how they stop carrying it alone.
