STRROI is a short-term rental (STR) investment analysis platform. It pulls live MLS listings, scores every property for STR return on investment (ROI) using real Airbnb comps, and generates AI-written deal memos, so investors can underwrite deals faster and with more confidence.

How does the buy rating work?

Every property is scored 1-10 based on cash-on-cash return (35%), cap rate (30%), monthly cash flow (20%), and property quality signals (15%). Scores of 8-10 are Strong Buy, 6-7 are Buy, 4-5 are Hold, and below 4 are Pass.

What data does STRROI use?

STRROI combines live MLS listing data with real short-term rental comp data: the same active listings your competition will be booking. Cap rates, ADR, occupancy, and cash flow are all calculated from real market data, not estimates.

What is an AI Deal Memo?

An AI Deal Memo is a full investment analysis document generated by AI in under 30 seconds. It includes an investment thesis, comparable rental analysis, risk factors, financing scenarios, sensitivity tables, and a buy/pass recommendation, formatted to share with partners or lenders.

Is there a free plan?

Yes. The free plan gives you full access to the STRROI interface using demo market data, so you can explore every feature before committing. Paid plans start at $24/month and unlock live MLS searches, real STR comps, and AI-powered analysis.

How is STRROI different from AirDNA or Mashvisor?

AirDNA and Mashvisor show you STR performance data for properties you already own or are researching manually. STRROI starts from live for-sale MLS listings and automatically underwriting each one for STR viability, so you're finding deals, not just analyzing them. The AI Deal Memo feature is also unique: no other STR tool generates a full underwriting memo from live comps.
