How do lenders count Airbnb income?

[Mike Day]

Anyone aware of the ins and outs of how Fannie Mae-backed conventional lenders count income from Airbnbs? Specifically, my question is whether you can acquire a short-term rental, then immediately turn around and use the income from it to qualify to purchase another property. With conventional long-term rentals, if you're an established landlord, lenders will count the income from a new rental property right away, allowing you to use it to qualify to purchase another. Say you purchased a property that makes $500 a month in May 2024, and now it's August 2024 and you want the lender to count that income--they'll count $6k, not just $1500, with no need to see your taxes. Does it work that way for short-term rentals too? Or are the lenders wanting to see a full year of them on your taxes before they'll count the income?
