Do you think housing in your area is getting more affordable or less affordable?

The Cambridge Housing Authority has bought or is closing on six properties and portfolios across Cambridge in a single year. The moves come as a commercial real estate downturn has drained private-sector competition for these deals.

Why it matters

Rising hard construction costs and capital costs have pushed institutional developers out of the region, leaving the authority's acquisitions with far less competition. The shift matters for Cambridge residents because the authority expects its deals to add at least 300 units to its portfolio over the next five to eight years.

Hard construction costs for multifamily development have risen over 50 percent and the cost of capital has risen 20 to 30 percent, while regional rents grew just 1.1 percent according to the Greater Boston Housing Report Card. The authority is closing on an undisclosed building with roughly 100 units, and the source does not say how the 300-unit goal will be funded beyond the authority's reserves and city dollars.

Over the next five to eight years: Acquired properties are expected to add at least 300 units.

Market Landscape

The authority's buying spree fits a broader pattern in which many investors have shifted from Boston to markets with friendlier rent growth and regulations. Public acquisitions are filling a gap as private developers pull back from the region's multifamily market.

Cambridge renters may see additional affordable units added to the local supply as the authority's acquisitions come online over the coming years. Residents near the Massachusetts Ave. conversion and the Porter St. site will see construction and changes to nearby housing as these projects proceed.

The takeaway

Public housing agencies can fill gaps left by retreating private developers, but the scale of need in Greater Boston far exceeds what a few acquisitions can deliver. Watch whether the authority's funding sources keep pace with its five-to-eight-year goal.
