How to get a Short Term Rental in Southern Indiana (Brown County)

Hello,

My wife and I own 4 longer term rentals in Indiana. We are wanting to buy a cabin somewhere in southern Indiana that we can use as a vacation home for our family to use but also rent out when we are not there. Brown County is the most popular spot, however, doing a little bit of research I have learned that Brown County restricts the amount of short term permits and the best way to get one is to buy a property that already has a permit. I know this is one option but wanted to see if anyone could point me in the right direction to know of any surrounding cities or areas that still fit this bill and can perform well. I am very new to STR so any advice or pointers in general would be great including how to run numbers and also what to look for. The floor of my investment is really to just break even in cash flow but give us a place to use; obviously if it can be higher than even better.

Thanks in advance,

Connor
