The problem is evidence, not the product
Investors looking for an Airbnb loan without rental history usually assume the obstacle is the product. It is not. A short-term rental can be financed on the property own income the same way a long-term rental can. What is missing is the operating history that would normally prove what that income is.
So the real question is what a lender will accept in place of history, and the honest answer is that it depends which basis the file is underwritten on. There are two, and they produce different files.
