An STR purchase has two failure modes: buying the wrong property, and buying the right property on the wrong numbers. The agent protects you from the first, the data from the second, and neither replaces the other. Here is the vetting that separates help from salesmanship.
What to ask an agent
Do you own or operate short-term rentals yourself? How many STR transactions have you closed in this specific market in the last year? Will you show me the underwriting behind the listing you are excited about — not the brochure, the numbers? What do you know about the permit caps, zoning overlays, or pending ordinances here? And can you introduce me to the local bench — cleaners, handymen, managers? That last one is a quiet test: an agent with no operational network has never had to make one of these properties actually run.
What to ask of the data
Revenue estimates from platforms like AirDNA and Rabbu are modeled from active-listing data, which makes them strong for comparing markets and property types and weaker for predicting one specific address. Ask what the estimate is built on and how deep the comp sample runs in your submarket. Look at seasonality curves, not just the annual number — a market that earns its year in ten weekends is a different business. Then cross-check the model against the real calendars and rates of three to five comparable live listings before you trust it.
Red flags
Guaranteed revenue anywhere in a listing sheet. Projections nobody will stand behind in writing. An agent who has never once asked whether the property can be legally permitted — that question should arrive before the showing, and our free permit data makes it easy to check yourself. And buying into a market where you have not priced a cleaning: operations are what turn paper returns into real ones, and cleaning capacity is the first place paper meets reality.
