If it's currently an STR they should be able to provide you with the p/l statement from prior years so you can see gross rents, operating expenses, average daily rates and occupancy levels.

As others have mentioned, DSCR loans are generally for turnkey rentals (although outdated rentals may still qualify depending on the level of deferred maintenance).
