The makeup of the block

Every home, plotted by size and assessed value — press play and watch the block reprice from 2016 to 2027. One bubble per house (area = lot size), colored by who owns it; a gold ring marks a material assessment exemption whose legal basis is not established by the roll. Click a bubble for its report.

Safety & quality of life

Within 200 metres of the block over the last 12 months: 181 reported crimes (about 15 a month, 35% of them violent) and 249 resident 311 requests to the city. A busy commercial corridor logs far more than a quiet residential block, so read this against nearby blocks, not the citywide total.

4
4 properties on this block show a material assessment exemption. At the current rate, the difference between full and taxable assessments reduces the block's annual estimate by about $41,742. OPA's numeric split does not establish whether any row is Homestead, an abatement, another program, or when treatment changes.

Who really pays

Philadelphia's 1.3998% rate applies to the taxable assessment. The OPA roll shows exemptions that can make an estimate lower than the full assessed-value scenario; this chart does not identify their legal basis.

14 homes pay the full 1.40%7 pay less
$10,416pays now $39,754at the full rate

One large gap: 3900 Warren St has a $10,416/year assessment-based estimate on $2.8M assessed value — about 26% of the $39,754 full-assessment scenario. Verify the exemption basis and live account before relying on either number.

The block as an asset

Read like a financial asset, this block has beaten the Philadelphia market, compounding +8.3% a year against the city's 6.5%.

Where this comes from

Methodology & freshness

This report was assembled Jul 10, 2026, 2:55 AM ET. Available City datasets are queried from OpenDataPhilly (phl.carto.com) and the cited City ArcGIS feeds; record queries paginate rather than silently taking a first page. “Unavailable” means the source query failed or was not supplied, not “no record.” Reports re-pull on view after seven days and on an overnight rolling schedule; citywide benchmarks recompute weekly. Source dates still govern: the parcel-level tax-delinquency snapshot is June 2022 and the separate detailed tax ledger ends in 2016, so neither establishes today’s balance. The live balance and date-effective payoff must be verified in Tax Center. AI-written passages are grounded in the assembled record and rejected if they state a number the record does not hold.
