Lenders evaluate STRs using three qualifying scenarios. The tool picks the best one that applies (marked "Selected"). World 1 uses the long-term lease rate. World 2 uses your projected STR average. World 3 uses documented historical income.
State TX legality status: UNCERTAIN — STR income is not permitted for qualifying in this state; the engine falls back to World 1 long-term-lease rent. Selected scenario: World 1 — Long-term Market Rent, qualifying rent used: $3,200/mo.
Each monthly bar shows the occupancy index for that month (US national AirDNA seasonality data) and the resulting monthly DSCR. Green = covers the payment; yellow = just covers; red = cash shortfall that month.
