I would first check city/county STR rules and HOA (if applicable).

I sent an invite to a prospective applicant that qualified and Looked high and low for the invite form with some additional notes to the applicant only to find out that it is not even on the platform at all, anywhere but in an email confirmation I received.

And IMHO, the prices are dropping big time (on avg. 10K/month...houses that were above 300K a year ago are not selling at 250K now) and the available rentals saturation is worse than I seen during summer season (with rents dropping from 1$-1.08/sqft to 0.8$/sqft and very little contacts and applications...just go in Zillow and look how many rentals are on the market now in Kyle, New Braunfels or Converse).
