A mediocre property in a great market usually outperforms a great property in a mediocre market. Most first-timers get this backwards — they buy where they vacation, then wonder why the numbers don't work.
And one filter that trumps all five: regulation risk. A market with beautiful numbers and hostile rules is not a market. That's the whole next lesson.
Two practical notes. First, resist the urge to pick a market because you love visiting it — you're buying a business, and you can vacation in your cash flow. Second, don't just look at today's snapshot; pull 2–3 years of data where you can, because the direction of a market matters more than its current level.
ACTION: Shortlist 3 markets using the Market Comparison tool and rank them by ADR, occupancy, and regulation risk.
Next lesson: the single mistake that kills more STR investments than bad pricing ever will — and the 10-minute check that prevents it.
