Build-to-Rent Is Shifting Toward Secondary Cities — Here's the Real Data

Build-to-rent (BTR) — purpose-built rental communities designed and managed as a single asset rather than sold off as individual units — has become one of the defining multifamily investment themes of 2026, and increasingly the action is happening away from the most expensive gateway cities. Secondary and tertiary markets are drawing capital that used to concentrate almost exclusively in places like San Francisco and New York, as investors look for better yields and lower entry costs.

The Real Numbers Behind the Shift

Some of the strongest rent growth in early 2026 has shown up in non-traditional markets — cities like Buffalo, Pittsburgh, and Reno posted year-over-year rent growth around 10%, outpacing many larger, more expensive metros (National Apartment Association). Secondary markets are also offering a real yield advantage: cap rates in these markets are running roughly 100 to 200 basis points higher than in primary gateway markets, even as the overall gap between primary and secondary cap rates has been narrowing to historically tight levels, according to Morgan Stanley Real Estate Investing (CREDA). CBRE expects multifamily cap rates to stay broadly stable through 2026, with only incremental compression expected in later years.

Why Secondary Cities Are Pulling Capital

A few forces are converging. Land and construction costs remain dramatically lower outside the most expensive coastal metros, letting developers pencil out projects that simply don't work financially in San Francisco or New York at current interest rates. Secondary cities with more diversified local economies — spanning healthcare, education, logistics, and light manufacturing rather than a single dominant industry — also tend to produce steadier rent growth than boom-bust single-industry markets. And renter demand itself has shifted: households priced out of homeownership by mortgage rates that have been running close to 7% through much of 2026 (Bankrate) are staying in the rental market longer, supporting demand for professionally managed, amenity-rich BTR communities as an alternative to older, less consistently maintained rental housing stock.

What's Actually Driving BTR's Trajectory Now

Industry analysts increasingly describe BTR's growth as depending less on renter demand alone — which has remained solid — and more on how well developers and operators navigate capital constraints, construction timing, and local policy uncertainty (National Apartment Association). That's a meaningfully different framing than a pure demand story: with financing costs elevated and construction costs still volatile in many markets, execution risk on the supply side has become just as important to underwrite as demand fundamentals.

The Regulatory and Financing Realities

Zoning remains the first real obstacle in most cities — multifamily and BTR projects often fall under "high-density" categories that trigger larger lot-size, parking, and setback requirements, even in smaller metros. Many developers have responded by pursuing mid-rise designs (roughly three to four stories) that fit under less restrictive zoning thresholds and require less land per unit, a pattern showing up across secondary markets nationally as construction costs push developers toward lower-density, faster-to-build formats. On the financing side, conventional lenders have historically been slower to treat BTR as a distinct, well-understood asset class in smaller markets with shorter track records, which has opened space for specialty multifamily debt funds — though at borrowing costs that reflect today's higher-rate environment rather than the more favorable financing conditions of a few years ago.

What This Means for Investors

The core thesis — that secondary cities offer better risk-adjusted yields than saturated gateway markets — has real data behind it in 2026: measurable rent growth outperformance in specific secondary metros, a persistent cap rate premium over primary markets, and a renter base that's staying in the rental market longer due to elevated mortgage costs. But the sector's own analysts are increasingly flagging execution risk — capital availability, construction timing, and local policy — as the bigger swing factor than demand itself. That argues for underwriting individual deals and local regulatory environments carefully rather than assuming secondary-market BTR is a uniformly favorable trade regardless of city or sponsor.

FAQ

Are secondary cities really outperforming gateway markets in build-to-rent right now? In several specific cities, yes — Buffalo, Pittsburgh, and Reno posted roughly 10% year-over-year rent growth in early 2026, and secondary markets generally offer cap rates 100-200 basis points higher than primary gateway cities.

Why are cap rates higher in secondary markets? Lower land and construction costs, plus less institutional capital competition, generally produce higher going-in yields than saturated primary markets, though the gap has been narrowing to historically tight levels in 2026.

What's the biggest risk factor for BTR investments right now? Increasingly, execution — capital availability, construction cost and timing, and local zoning and policy — rather than renter demand, which has remained comparatively stable.

How are elevated mortgage rates affecting the BTR market? With 30-year mortgage rates running close to 7% through much of 2026, more households are staying in the rental market longer rather than buying, which supports demand for professionally managed rental communities like BTR.

What zoning strategy are BTR developers commonly using in secondary cities? Many are pursuing mid-rise designs (roughly three to four stories) that fall under less restrictive zoning categories than high-rise multifamily, allowing faster approvals and lower land requirements per unit.

Is financing readily available for build-to-rent projects in smaller markets? It's improving but still uneven — conventional lenders have been slower to embrace BTR as a distinct asset class in markets with shorter track records, leaving more of that financing gap to specialty multifamily debt funds.
