Search an address
Type any address, city, or ZIP. Google Places autocomplete resolves it to a precise parcel (a deterministic mock stands in until a key is added).
Pull the records
Lotline fans out to MLS, PropertyRadar, ATTOM, and RentCast through swappable adapters — comps, assessments, specs, and rent in one pass.
Crunch the analysis
Comps are adjusted and reconciled, taxes projected, the mortgage and returns modeled, and a remodel scope costed — instantly and deterministically.
Decide & share
Read it in a cinematic workspace, tweak the investment and remodel assumptions live, then export a print-ready CMA to share with a client.
Demo data. Every property, comp, tax record, and estimate on this page is synthetic and generated for demonstration — not a real listing. Connect MLS, PropertyRadar, ATTOM, or RentCast (and a Google Places key) to serve live data with no code changes.

Honest answers, up front.
What Lotline does, where the live data comes from, and how to connect your own sources.
In production, Lotline pulls from MLS, PropertyRadar, ATTOM, and RentCast for comps, ownership, assessor records, and rent estimates, with Google Places for address search. Each source is wired as a swappable adapter behind a single provider, so you can run one source or all of them.
Yes — Lotline runs live. The market search pulls active for-sale listings from RentCast; property pages add county assessor records, FEMA flood zones, and U.S. Census data; and photos come from Google Street View. Values and scores are automated estimates — not appraisals. The separate MLS feed is a clearly-labelled sample, and the guided walk-through uses one example home.
The valuation, tax, investment, and remodel models use transparent, industry-standard formulas — similarity-weighted comp reconciliation, amortized mortgage math, cap rate and cash-on-cash, and national renovation cost bands scaled by region. On live data they produce a defensible starting point; they are planning tools, not appraisals or contractor bids.
Yes. Lotline already runs live on RentCast plus public records; to add or swap a source — a production MLS, ATTOM ownership, PropertyRadar — set its API key and the DATA_PROVIDER variable. Every page reads through one provider seam, so there's no code rewrite. The README documents each variable.
Real estate agents preparing a CMA or a listing pitch, plus investors and developers sizing up a flip or a rental. If you need to answer “what is it worth, what does it cost to own, and what would it cost to fix” for any property, Lotline is the workspace.
Pricing isn't set yet. Lotline is built for a usage-based model keyed to lookups and connected data sources, so a solo agent and a brokerage can each pay for what they pull.
