STR vs LTR analysis on every property
Every property has two answers. See both before you buy.
Most STR deals are only analyzed as Airbnbs. If they don't hold up as a long-term rental, you're taking on hidden downside. GemHaus shows you both — comps, rent estimates, full pro forma — in seconds.

The thesis
Most STR deals look great
until you run the LTR case.
Investors look at Airbnb revenue and assume the deal works. But if it doesn't hold as a long-term rental, the risk is higher than they think.
The best investors don't just chase upside. They understand downside. Every property should be analyzed as both a short-term and long-term rental — because the answer to which one wins isn't always obvious.

The category
Other tools answer half the question.
STR tools ignore long-term performance. Generic deal calculators ignore Airbnb. Spreadsheets ignore your time. GemHaus is the only tool built around the comparison itself.
