Built for investors

Find better listings without spreadsheet chaos.

InvestorSignalAI is not a replacement for your agent, attorney, inspector, or lender. It is a screening layer that helps you decide what deserves deeper due diligence before you spend time on calls, comps, and offers.

Deal Advisor

After you create a free account, choose a listing and we explain the investor case in plain English: why it may work, what could kill the deal, and what to verify before contacting the listing rep.

Create a free account first. Then this advisor shows real listings, score reasoning, underwriting risks, and contact options.

Market comparison

Compare multiple ZIPs from one screen. InvestorSignalAI pulls the same scored listing data used by Listings and Advisor, then summarizes price, DOM, score, and deal candidates.

Free accounts can track their profile ZIP. Investor and Pro plans can compare multiple markets.
Enter ZIPs separated by commas and click Load market feed.

Proof and details when users want them.

The main flow is now: create account → scan ZIP → see listings. Deeper methodology is available without making the page feel endless.

Accuracy standard
InvestorSignalAI should only present strong recommendations when sources, assumptions, and confidence support it. If data is weak, the app lowers confidence and tells users to verify comps, taxes, insurance, and repairs.
Backtest / safety gate
The prototype stress-tests estimates with conservative assumptions: rent down, taxes up, repairs up, insurance up. Offer guidance should only appear when the conservative case still works.
Beginner and pro views
Beginner view gives the verdict, reason, strategy, and next action. Pro view adds cap rate, cash-on-cash, DSCR, and max allowable offer.

Beginner-simple. Pro-detailed.

Same engine, two levels of clarity. No competitor owns this split well enough.

How the score works.

InvestorSignalAI is a screening system, not a recommendation to buy. Scores help decide what deserves deeper due diligence.

Methodology

What raises or lowers a signal

1
Asset type firstSingle family, condo, multifamily, land, and unknown listings are treated differently. Land is not rental-scored.
2
Yield disciplineGross yield, estimated rent, HOA, and price-to-rent pressure can cap or lower the score.
3
DOM is a warning and opportunityHigh days on market may mean negotiation room, but also condition, title, location, or pricing problems.
4
Missing data lowers confidenceMissing sqft, bed/bath, source, rent, zoning, or utility data is shown and reduces trust in the score.
Not advice

What the score is not

The score is not legal, tax, financing, appraisal, brokerage, or investment advice. It does not replace your agent, lender, attorney, inspector, contractor, rent comps, or local due diligence.

Before taking action: verify source data, rent comps, taxes, insurance, HOA, repairs, title, zoning, flood risk, and financing.
