The four-year buying boom.

Five years of average. Then four of acceleration.

From 2014 through 2018, New Haven recorded an average of about 188 corporate-property acquisitions per year. The city was growing modestly, the multi-family stock was changing hands at a steady pace, and the largest landlords were adding two or three buildings a quarter. Then came 2019, and 2020, and the pace broke from its trend.

Three things to notice. First, the 2019-2022 window doubled the prior five-year average — from ~188 to roughly 572 per year. Second, 2021 and 2022 weren't anomalous noise; they were two consecutive 700-parcel years, the highest two-year window in the data. Third, the post-boom years (2023-2024) returned to a still-elevated pace before 2025 spiked back up to within five percent of the 2022 high. The boom may not be over.

The groups that built themselves in four years.

The headline buyers of 2021 are easy to spot from sale dates. But the more interesting question is which groups assembled most of their entire portfolio during the 2019-2022 window. For some, it's a majority of everything they own today. These are the groups whose existence as we know them is, essentially, a 2019-2022 phenomenon.

The list reads as a snapshot of multiple kinds of buyer compressing into the same window. Reichman Brodie and Scherban are private family/investor groups whose New Haven footprints essentially didn't exist before 2019. Beacon Communities is a regional housing nonprofit that absorbed a single subsidized portfolio in this window. Vanguard Private Client and 831 Whalley Partners are vehicle-style entities — capital pools acquiring rental stock. Mandy is the largest absolute mover but, in percentage terms, looks moderate next to a half-dozen groups whose entire identity in this dataset is 2019-2022 buying.

Cheap money meets cheap stock.

The 2019-2022 acceleration in New Haven tracks national patterns. Federal Reserve rates dropped through 2019 and stayed near zero through most of 2021. Mortgage credit was cheap. Rental yields in mid-market Northeastern cities looked attractive against a hot national housing market. Single-family-rental (SFR) consolidation, which had been a Sun Belt story since 2012, shifted attention to denser old-stock cities where yields were higher per dollar of acquisition cost. New Haven, with a multi-family fabric that had been changing hands one or two parcels at a time for decades, was a target.

What the city absorbed was not, mostly, new construction. The 2,286 acquisitions across this window were almost entirely existing two-family, three-family, and small apartment buildings — the housing stock that historically traded between owner-occupants, small landlords, and family estates. The boom moved that stock from many small holders into fewer, larger ones. The entity layer changed; the buildings did not.

Quieter — but not quiet.

The two years that followed the peak (2023, 2024) saw acquisitions ease back to roughly 530 per year — still well above the pre-boom average of 188, but lower than the 2021-2022 high. That looked, briefly, like cooling.

2025 broke the cooling. 726 acquisitions — within a few percent of the 2022 high — closed in calendar year 2025 alone. Whatever drove the original wave is, by this measure, still active. Rates are higher than they were in 2021. The acquirer pool is consolidated. And yet the pace is back. Whether that means the same groups are continuing to scale, that distressed-seller windows are opening, or that new capital pools have entered, the data alone can't say. But it tells you to watch 2026 closely.

The first 126 days of 2026 produced 126 acquisitions — a pace that, if it holds, lands the year close to 350-400. That's below 2025's high but above the pre-boom baseline. A return to mean, or a pause before the next cycle. The weekly refresh on this site is the thing that lets you watch which.

Five questions for whoever covers this next.

• How does the 2019-2022 New Haven acceleration compare to comparable Northeast cities (Hartford, Bridgeport, Worcester, Providence)? The same wave should be visible in their assessor data; the comparison would tell us whether New Haven was a specific target or a representative one.
• Of the boom-era acquisitions, what share came from owner-occupant sellers versus other small investors? Sale-history records carry prior-owner data; this is computable directly from the dataset.
• Among the groups whose 2019-2022 share exceeds 70% of their portfolio, which still report any acquisitions in 2025-2026? The ones that don't may be in the hold-and-rent phase; the ones that do are still scaling.
• Which neighborhoods absorbed the most boom-era buying? The map already supports a hood-level view; what's missing is a time-filtered overlay that shows where in the city the wave concentrated by year.
• How did the boom-era capital structures behave? Look at the post-acquisition refinances and resales: nominal-price ($1) inter-entity transfers, mortgage activity, and the balance between LLCs and the LLPs covered in the previous Findings.

Each is reportable from this dataset alone.
