We have a short term rental on the coast of Alabama so perhaps I can help a little bit. We also use ours periodically throughout the year and rent it when we are not using it. Here are some things that come to mind, in no particular order:
- We choose not to stay in our condo during the high season because that's when the money is made. We also don't stay there Dec - Feb because that's snowbird season.
- Keep in mind you have an HOA to pay as well - that will impact your cash flow.
- Mother Nature is a beast. Hurricane Sally shut our complex down (and many others). We have not been able to rent our condo since mid September. Our re-open date is May 15, so that's 8 months of paying out of pocket. Insurance helped a little, but the majority of the cost was ours. In addition to lost rental revenue, we had to pay our HOA an assessment of several thousand dollars. Some complexes had to pay upwards of $10k in assessments.
- We use a property management company that manages our rentals. They charge 20% which is pretty typical for the area. We are just too busy at this point in our lives to do it ourselves.
I don't want to discourage you but those are just some things you may not have considered. We absolutely love it on the gulf coast and we are happy with our investment but sometimes we entertain the thought of selling it for something that would cash flow a little better.
