Questions
Is it free?
Yes. The map, nearby projects, the scores and the real price are free on every listing. Pro adds the full breakdowns and the one-page report, and every Pro feature is free for everyone until Dec. 1.
What does LotLine show?
For any listing: data centers, power plants and other projects within 25 miles; an environment check and a safety check; the share of recent home loans that went to investors; the city, school district and districts the home is in, and who sets power rates; and the all-in monthly cost, closing fees and taxes.
Does it rate schools or neighborhoods?
No. It tells you which school district the home is in, not how good the schools are, and it never rates neighborhoods or describes who lives there. It sticks to facts about places, with sources.
Where does the data come from?
Public records: the Census Bureau, EPA, FEMA, EIA, NOAA, HMDA home-loan data, FHFA and more, plus LotLine's own project tracking. Each number shows its source and date.
Is this advice?
No. LotLine summarizes public records into estimates. It isn't an appraisal, an inspection, or legal, tax or financial advice. Check anything important with the original source or a professional.
What do I need to use it?
Google Chrome on a computer (Mac or Windows). It works on Zillow, Realtor.com, Redfin and Homes.com, in the 50 states and D.C.
What do you do with my data?
LotLine runs in your browser. It doesn't sell your data or track you across sites. See the Privacy Policy.
