There are two buckets: your buy-in and your ongoing share of operating costs. Your buy-in is a 1/4 interest of the home's purchase price plus a one-time GoForth design and furnishing fee. That's it for day one. No hidden origination charges, no surprise closing-cost markups.
After that, you split the monthly operating costs four ways with the other owners. That covers property taxes, insurance, utilities, landscaping, cleaning between stays, and GoForth's property management fee. Think of it like splitting a dinner check — except the dinner is a fully managed vacation home and the check comes every month, predictably, with full transparency into every line item.
