Twenty-Year Research

Across 324 qualifying transfers, the five-year median moved from $660,000 in 2006–2010 to $1.435 million in 2021–2025. The long-run story is broad nominal growth; in inflation-adjusted terms, the two most recent eras were essentially level.

Four eras

The long rise was not one smooth line.

Five-year eras keep a small market readable, while property use and architecture explain what sat beneath each headline median.

One- and two-family properties remained the core of the market, but their balance changed from era to era. Small mixed-use properties total just six over 20 years; each era cell stays unreported.

Two decades, distilled

Three findings.

  1. 01 · Long-run step

    The largest nominal rise came before the latest era. Median increased from $800K to $1.200M between the middle two chapters.

  2. 02 · Purchasing power

    Recent real growth was flatter. Using New York-area CPI-U, the last two era medians were each about $1.51 million in 2025 dollars.

  3. 03 · Architecture in proportion

    A/A′ and B/B′ were nearly alike per 100 mapped parcels; G/G′ was modestly lower. I/I′ (n14), R/R′ (n12) and F/F′ (n9, limited) also clear the reporting threshold but sit outside this normalized comparison.

Read the method

Context before conclusions.

Methodology, definitions and privacy

The study reconciles qualifying NYC Department of Finance and ACRIS deed transfers from 2006 through 2025. Prices are nominal unless stated; New York-area CPI-U provides broad inflation context, not a house-price index. Reported property categories use tax-class data as a descriptive proxy and do not verify current legal use.

LPC families combine mirrored primed and unprimed variants and describe façade and fenestration, not floor plan, condition or rank. The normalized view uses mapped tax parcels in the internal crosswalk after aliases and conflicting assignments are removed. Cells below five are withheld. Subgroup samples of five to nine are labeled limited. No addresses, owners, parcel identifiers, exact transfer dates, maps, court rankings or address-to-type matches appear.
