Comparable Sales Analysis Platform
Stop Guessing.
Comp Like a Pro.
Comp Pro searches public records, assessor data, and property characteristics to find comps that actually match your subject property. Get similarity scores, suggested adjustments, and a value range backed by real data — not algorithms trained on listing prices.
Built by a NYS Certified Real Estate Appraiser and a data platform engineer.
Features
Everything you need to comp with confidence
Comp Pro combines public records, assessor data, and appraisal-informed logic into a single platform that handles the heavy lifting of comparable sales analysis.
Targeted Comp Search
Search by address, ZIP code, neighborhood, school district, or draw a custom radius. Filter by property type, bedroom count, square footage range, sale date, and more to surface comps that genuinely match your subject property.
Similarity Scoring
Every comp is ranked with a similarity score based on how closely it matches your subject across the factors that matter most in appraisal methodology — gross living area, lot size, age, condition, proximity, and property type. No more eyeballing a list and guessing which comps are strongest.
Suggested Adjustments
Comp Pro generates adjustment recommendations for GLA, lot size, garage, basement, condition, and time based on local market data. Each adjustment is transparent and editable — you stay in control of the final analysis while saving hours of manual calculation.
Value Range with Confidence Score
Instead of a single point estimate, Comp Pro delivers a value range with a confidence score that reflects the strength of your comps and adjustments. A plain-language narrative explains the reasoning so you can communicate your conclusion to clients, partners, or lenders.
Interactive Maps and Charts
Visualize comps on an interactive map with sale prices, distances, and property details at a glance. Sales history charts and neighborhood context help you spot trends and outliers before they skew your analysis.
Branded PDF Reports
Export professional reports with your selected comps, adjustment grids, maps, valuation narrative, and disclaimer language. Reports are ready to share with clients, lenders, or partners — no reformatting required.
How It Works
From address to valuation in minutes
Comp Pro handles the research, matching, and adjustment calculations so you can focus on making informed decisions.
Enter Your Subject Property
Start by entering the address or key characteristics of the property you need to value. Comp Pro pulls property data automatically so you spend less time on data entry and more time on analysis.
Review Matched Comps
The platform searches public records and assessor data to surface recent sales that match your subject property. Each comp is scored for similarity based on location, size, age, condition, and property type — so the strongest matches rise to the top.
Refine Adjustments
Comp Pro generates suggested adjustments for differences in gross living area, lot size, garage, basement, condition, and time. Every adjustment is transparent and editable. You can accept the suggestions, modify them, or override them entirely based on your market knowledge.
Get Your Valuation
Receive an estimated value range with a confidence score and a plain-language narrative explaining how the conclusion was reached. Export a branded PDF report that is ready to share with clients, lenders, or investment partners.
Who It's For
Built for professionals who need comps they can trust
Realtors
Produce stronger listing presentations and more competitive offer analyses. Comp Pro gives you a data-backed pricing opinion that goes beyond a basic CMA — with similarity scores, adjustment breakdowns, and narrative explanations you can share directly with clients.
Real Estate Investors
Calculate after-repair value with confidence before committing capital. Whether you are evaluating a flip, running a BRRR analysis, or underwriting a rental acquisition, Comp Pro helps you find comps that reflect the finished condition of your project and quantify your margin of safety.
Appraisers
Accelerate comp selection and adjustment calculations without sacrificing the rigor that USPAP requires. Comp Pro is built on appraisal methodology — paired sales logic, market-derived adjustments, and transparent reasoning — so it fits naturally into your existing workflow.
Lenders and Brokers
Get preliminary valuation support before ordering a formal appraisal. Comp Pro helps loan officers and mortgage brokers identify potential value issues early in the process, reducing surprises at underwriting and keeping deals on track.

Frequently asked questions
Is Comp Pro a replacement for a licensed appraisal?
No. Comp Pro is a comparable sales analysis tool that provides data-backed valuation estimates. It is not a substitute for a formal appraisal performed by a licensed or certified appraiser. When a lender, court, or government agency requires an appraisal, you need a licensed professional. Comp Pro helps you make more informed decisions and produce stronger analyses, but the output is an AI-assisted opinion of value, not a certified appraisal report.
What data sources does Comp Pro use?
Comp Pro pulls from public records, assessor data, tax records, deed records, and property characteristics databases. In New York City, this includes PLUTO data from the Department of City Planning and ACRIS records from the Department of Finance. The platform enriches this data with similarity scoring and adjustment logic informed by professional appraisal methodology.
How are the suggested adjustments calculated?
Adjustments are generated using logic informed by paired sales analysis and market-derived adjustment methodology — the same approach professional appraisers use. The platform analyzes local market data to estimate the value contribution of differences in gross living area, lot size, condition, garage, basement, and time. All suggested adjustments are transparent and fully editable so you remain in control of the final analysis.
What markets does Comp Pro cover?
Comp Pro is launching with coverage of the New York City metropolitan area, including all five boroughs, Long Island, and the surrounding suburbs. Coverage will expand to additional markets based on user demand and data availability.
Can I try Comp Pro before subscribing?
Yes. Comp Pro offers a free trial so you can experience the platform and evaluate the quality of the comp analysis before committing to a subscription. No credit card is required to start.
Who is Comp Pro built for?
Comp Pro is designed for real estate professionals who need reliable comparable sales analysis — including realtors preparing pricing opinions, investors calculating after-repair value, appraisers accelerating their workflow, and lenders seeking preliminary valuation support. The platform is built to serve anyone who makes decisions based on property value.
