Build the right legal foundation and protect what you’ve built.
Forming an LLC is not the same as maintaining it. Courts examining liability don’t care about your certificate of formation — they examine your financial records. Commingling is the most commonly cited veil-piercing factor across virtually all jurisdictions.
The S-Corp management entity structure applies to a narrow situation: an STR operator providing substantial services to guests such that income is correctly on Schedule C and subject to SE tax. For most STR operators, the structure provides zero benefit.
A Series LLC isolates each STR property in a legally separate cell within a single parent entity. A lawsuit against one cell cannot reach the assets of another. But the protection is only as strong as the cell separation you actually maintain.
Transferring a personally titled STR into an LLC technically triggers the due-on-sale clause in your mortgage. The correct approach is transparent lender notification before the transfer — not transfer first and disclosure later.
The answer isn’t the same for every operator. Here’s how to think through the LLC vs. S-Corp decision based on your specific situation.
