About PropLab

PropLab is an AI-powered real estate deal underwriting platform designed for investors, including flippers, wholesalers, rental investors, and acquisition teams. The tool analyzes a property address or a link from MLS, Zillow, or Redfin to deliver key outputs such as After Repair Value (ARV) estimates, rehab cost projections, weighted comps with adjustment breakdowns and confidence scores, and a Maximum Allowable Offer. It automates the entire underwriting workflow—from pulling comparable sales to generating offer-ready reports—by cross-referencing public records, tax assessments, and market data with AI-driven adjustments and risk signals. PropLab eliminates the need for manual spreadsheets and MLS access, enabling users to evaluate deals quickly and make data-driven offers. The platform produces professional, lender-ready PDF reports that can be shared with partners or sellers, streamlining the decision-making process for property investments. Trusted by investors nationwide, PropLab aims to reduce deal analysis time from hours to minutes while improving accuracy and consistency in underwriting. It supports all US markets, though data coverage may be denser in urban and suburban areas.

Frequently asked questions about PropLab

Do I need MLS access to use PropLab?

No. PropLab pulls property data from multiple sources including public records, tax assessments, and market data, so MLS access is not required to obtain accurate comps and ARV estimates.

How accurate are the comps and ARV estimates provided by PropLab?

PropLab’s AI cross-references multiple data sources and applies smart adjustments based on property characteristics. Users report ARV estimates within 3-5% of actual sale prices in most markets, compared to traditional appraisals which have a 5-10% margin of error.

What is ARV in real estate, and why is it important?

ARV (After Repair Value) is the estimated market value of a property after all renovations are complete. It is a critical number for fix-and-flip or BRRRR deals, as accurate ARV is cited by over 80% of successful investors as the top factor in deal analysis.

What markets does PropLab support?

PropLab works in all US markets, with nationwide property data coverage. Data density varies by region, with urban and suburban areas typically offering the best coverage.

Can I export or share the reports generated by PropLab?

Yes. Every analysis generates a professional PDF report that can be downloaded, shared with partners, or sent to sellers. The reports are designed to be lender-ready and offer-ready.

How does PropLab handle deal analysis compared to manual methods?

PropLab automates the entire deal analysis workflow—including pulling comps, calculating ARV, estimating rehab costs, running profit scenarios, and generating an offer price—in about 60 seconds. Traditional manual analysis can take investors 6-8 hours per deal.
