Your question is not so cut and dry. It is quite possible that it will pay for itself but there are several things you have to take into consideration when pricing it like taxes, maintenance, and association dues to name a few. So depending on the price of the home and if you will have a mortgage on it may or may not pay for itelf. I suggest that you find out what the prices are for rentals in the area you are thinking of buying so you can use that as a starting point. I can help you with that. You can market a vacation rental through Craigs list and sites like that or you can market it with a Real Estate . Better Homes and Gardens Real Estate Wilkins & Associates has a vacation rental department to help you rent it.
I hope that helps answer your quetion. If I can be of any other service please feel free to contact me at 570-977-5623 direct or by email at email@example.com
