I'm assuming you are trying to shoehorn this into the 1007. So you have a gross rental, sometimes disclosed, sometimes based on the nightly rate (on season/off season) x the occupancy rate (sometimes estimated sometimes owner provided), less all the expenses associated with the operation of a short term rental (cleaning, maintenance, Vrbo Fees, Local STR tax, upgrading, anything listed to the IRS), then you probably should make an adjustment for the 'personal property' and you divide the net rental income by 12 and plug it into the form. I've never had Fannie or a lender gripe over it, but by all means disclose that the subject property is being used as a short term rental. Hope that helps. Oh, and the monthly rentals used as comparables are 'gross' and do not deduct for insurance and property taxes typically.
