Save and Lotlyze Score

Pro includes up to 100 saved supported NYC and Chicago residential 2–6 unit buildings. Saves are retained but locked after downgrading, and removed on account deletion. Lotlyze Score is a proprietary algorithm developed by Lotlyze. Its 1–100 score summarizes unit/permit evidence, comparable-sale value when asking price is supplied, income and rent trends, reported property crime, and transit proximity. Optional user-entered days on market and price cuts can increase the score. Missing price uses a neutral value, not evidence of a bargain; other missing factors and risk caps affect the result. Data coverage and limitations accompany scores. NYC and Chicago scores use city-relative evidence; a mixed-city ranking does not imply comparable projected returns. NYC unit evidence without occupancy corroboration is capped and does not certify legal units.

Lotlyze Score is a research tool, not investment advice. Scores and source data may be incomplete, outdated, or change with methodology and inputs. User-entered listing data is not verified MLS data. Scores are not appraisals, investment recommendations, return predictions, legal-unit certifications, or neighborhood safety ratings. Income and crime measures describe aggregate historical records, not individual residents. Verify all material information independently.

Acceptance

By using Lotlyze, you agree to these Terms of Use. If you do not agree, please do not use the site. These terms apply to all visitors, registered users, and API consumers.

About the Service

Lotlyze provides a free lookup tool for New York City public property records, including ACRIS deed and mortgage records and New York City Department of Buildings permits, violations, complaints, and filings. It also provides Chicago residential 2–6 unit-count evidence, permits, violations, building facts, and sales. Sources include NYC Open Data, the Chicago Data Portal, and Cook County Open Data (Socrata). Data is provided as-is. Chicago unit counts are public evidence, not certified legal counts. An issued permit does not prove completed work or legal occupancy. City records match street addresses and may omit records at other addresses on a parcel. Results are limited to up to 200 permits, 200 violations, and 20 sales per Chicago lookup.

No Warranty; Accuracy of Data

The information displayed on Lotlyze is sourced from third-party government databases that we do not control. We make no representations as to the accuracy, completeness, or timeliness of any data. Lotlyze is provided "as is" without warranty of any kind, express or implied.

Do not rely on Lotlyze as a substitute for professional legal, financial, or real estate advice. Always verify critical information against primary sources (ACRIS, NYC DOB BIS, NYC Department of Finance, Chicago Department of Buildings, and Cook County Assessor). For a certified Chicago legal unit count, request a Residential Unit Verification from the City's Department of Planning and Development.
