Built so one bedroom can change hands without the whole house wobbling.
Two things make Casita work where shared ownership usually breaks: how it's structured, and how it's protected.
The structural choices
Permanent ownership, not a timeshare
You own your bedroom for as long as you hold your share — no rotating weeks, no schedule, no shared calendar. That is what separates Casita, legally and practically, from vacation-home fractionals.
The LLC borrows, not you personally
The home is owned by an LLC that carries the mortgage. Owners hold membership units governed by an operating agreement, so no one is jointly liable for anyone else's share. If one owner defaults, the LLC handles it without interruption.
House character is declared at formation
Every home is set as child-free or family, pet-friendly or pet-free, quiet or social, Airbnb-friendly or strict-occupancy — before anyone moves in. Owners self-select into a house that matches their values, which removes the conflicts that wreck most shared living.
The layers of default protection
The most common question about co-ownership is what happens to the mortgage if one owner can’t pay. The answer is a sequence of defenses — no owner is ever personally liable for another’s failure.
Underwriting prevents most defaults
Every owner must show income of at least three times their monthly carrying cost, six months of carrying cost in savings, a 680+ credit score, and stable employment. These filters remove most would-be defaulters before anyone closes.
The LLC carries reserves
Each LLC is funded at closing with several months of mortgage payments. If an owner stops paying their maintenance fee, the LLC keeps paying the mortgage from reserves while the issue is resolved. No missed payment, no risk to the building.
Replacement coverage, as Casita scales
On the roadmapModeled on landlord rent-guarantee insurance: a master policy that covers a missed maintenance fee from day 60 until a replacement owner is found. This layer comes online as the portfolio grows large enough to underwrite it.
Re-sale of the defaulter's units
If a default isn't cured, the owner's membership units are re-sold to a new vetted owner who pays their share plus any back-due maintenance, and the LLC's reserves are replenished. The exiting owner is made whole at fair value minus the cure cost.
No condo or single-family home bought the ordinary way has this layered protection. It is the reason Casita works.
