I know this is not exactly answering the question you have, but I highly suggest you figure out whether this will be your home that you rent out on the side or a property you buy as an investment in order to rent it out. If it’s the first, there’s a good chance a standard mortgage would be fine. If it’s the latter, then you’ll most likely need a commercial property.
The taxes will be much more complicated than just standard income taxes no matter which way you go. If you choose to live there and rent it out, you’ll have to divide the expenses between personal and “business”. If you buy it to rent, then I suggest you place the property into a business (an S-corp or an LLC are two common choices), and then all the expenses are deductible. But you’ll need to keep books for the business, including a balance sheet, etc.
Please consult someone like a CPA or a business advisor before you go down this path of buying for the main purpose of short-term renting. My day job is in developing business plans and reviewing the financials for a Fortune 10 company in Houston, and I find the tax laws challenging to understand. (Our home is in an S-corp, and I do our taxes.)
