@Kushal Dalal If you have been using LLCs thus far and are familiar with the process, I would continue to use them and use one per property regardless of state, unless the property values were very low then maybe I would consider trying to put several into one LLC to simplify things on the administrative side.Another thing to consider is that with STRs, you typically have some host liability coverage through the booking platform and be sure to get a specific STR policy through your insurer as that will cover more on the liability front than a standard insurance policy would.
