================================================================================ PURPOSE ================================================================================ We are gathering data from Zillow, the City of Boston, the Massachusetts Secretary of State, and the Suffolk Registry of Deeds on one property: 42-44 Hano Street, Allston, MA 02134 (PID 2201796000). The goal is to collect and organize property data. For valuation analysis and a potential tax abatement appeal. Read Documentation/condensed-memory.txt This is a pure-content, agentic, folder. We gather data, and document the trail to get it. We don't save raw code. Why? because the agent can run commands. And we become leaner. We are probabilistic and narrowly focused. Rule: no redundancy. All content has a home. ================================================================================ REPOSITORY MAP ================================================================================ Documentation/ — Complete data pipeline walkthrough: code-recipes.txt — curl commands, Puppeteer selectors, and consolidation pseudo-code. condensed-memory.txt — The short version: what we did, what we learned, where we are, where next. long-memory.txt — Narrative of everything learned: how investigations unfolded, what each scrape produced, what broke and what worked. should-i-appeal.txt — Abatement recommendation with full evidence: comparable sales, valuation methods, market trends, conclusion. Scrape/ — Raw data from external sources: city-of-boston/ — ArcGIS + data.boston.gov (assessment, tax, permits) secretary-of-state/ — Corporate entity lookup (HANO DEV HOLDINGS LLC) registry-of-deeds/ — Property deed records zillow/ — Zillow detail via Apify Consolidate/ — Merged property profile (JSON + TXT), assembled by following the Consolidation section of Documentation/code-recipes.txt. ================================================================================ DATA SOURCES ================================================================================ Four sources feed the property profile, each contributing a different layer. The City of Boston is the most open — its ArcGIS API and CKAN datastore are fully open, no key needed. A single curl command pulls the full FY26 tax assessment (land value, building value, condition grades, room counts). Another pulls 14 years of tax history and 10 building permits — $378K of work, six still open. This is the foundation: what the city thinks the property is worth, and why. Zillow adds the market lens: sold prices, Zestimate, property features, and neighborhood school data. Scraped through Apify actors because Zillow blocks direct access. The detail scraper gives us a full price history with seven sales from 1996 ($74K) to 2018 ($670K), and Google Search Scraper bridges addresses to Zillow URLs when we don't have them upfront. The Massachusetts Secretary of State confirms the ownership structure. Behind an Incapsula wall that blocks curl, so it requires headful Puppeteer — but the site is simple once you're in. Revealed that HANO DEV HOLDINGS LLC was involuntarily dissolved in 2023, yet still appears as the property owner of record. The Suffolk Registry of Deeds anchors it all. An ASP.NET WebForms site that requires native
