How do investors and quant researchers actually work this slice?

Investors and quant researchers arrive at multifamily REITs with a specific complaint: the cohort is small, vendors price it as an afterthought, and most free sources serve retail traders rather than backtests. Datadory catalogs 14 pooled records for Multi-Family Residential REITs - 3 primary datasets, all free, backed by 11 related records from adjacent industries such as Diversified REITs and Commercial & Residential Mortgage Finance. All three primaries rate relevant for this persona, ranked by signal value: SEC EDGAR Company Search & Filing Archive at relevance 5 and quality 10, Yahoo Finance - Equity Quote & Historical Data Pages at relevance 3, and Nareit Residential REIT Sector Page at relevance 2 with quality 8. Mean quality runs 8.0 out of 10 against a 7.81 catalog-wide average.

The workflow splits into three layers: per-filing fundamentals you can timestamp, a cross-sectional quote-and-multiple screen, and sector aggregates that tell you whether a single name is abnormal. The honest answer to "is this slice enough for a factor model" is yes for fundamentals and calibration, partially for prices - and the sections below show exactly where each layer comes from.

Log three reconciliation traps before modeling. Nareit's own counts disagree - 15 residential REITs in the FTSE overview, a claim of 18 on the FTSE Nareit US Real Estate Indexes, and 28 rows in the company directory with unstated inclusion criteria. The site's anti-bot challenge limits automated access, so treat it as a browser-read source. And neither the T-Tracker nor the overview archives vintages; the occupancy cell rendered blank for the latest quarter during research, so verify before imputing. Per-company FFO still comes from XBRL facts in EDGAR filings, which keeps the calibration join on CIK and period rather than on a vendor's ticker mapping.

For rate context, FRED - Federal Reserve Economic Data (St. Louis Fed) (quality 10) serves hundreds of thousands of series through a free REST API returning up to 100,000 observations per request, with ALFRED vintage dates for genuinely point-in-time macro. Backtest-length total returns come from the Nareit REIT Market Data Reports Hub, whose monthly historical workbook spans December 1971 through June 2026 across 664 rows and 42 columns at no charge - and the 166-company Nareit REIT & Public Real Estate Company Directory filters to Residential when a comp set or prospect universe needs building.

Questions worth asking

Is SEC EDGAR enough for a point-in-time multifamily REIT fundamentals panel?

Yes. The companyfacts API exposes 593 us-gaap concepts for Equity Residential (CIK 0000906107) with fiscal year, fiscal period, form type and accession number on every fact, so restatements persist as additional values. Submissions JSON holds roughly 1,000 recent filings inline; deeper history requires walking paginated archive indexes.
