Financialization of trailer parks and single family houses

Trailer parks.  The New Yorker has an article, "What Happens When Investment Firms Acquire Trailer Parks," about how large property firms and hedge funds are buying trailer parks, typically places of comparatively low cost housing, and significantly raising the cost of living there.

Traditionally, a household owns the trailer but rents the lot.

I've argued that community housing master plans should include trailer parks as a type and aim to put control of these properties into the social housing sector or community land trusts.

But cities, looking for higher revenue streams from property aren't inclined to take much initiative when it comes to this property type, especially when it comes to higher value redevelopment ("Trailer parks moving out of Fayetteville nothing new, officials say," Northwest Arkansas Democrat Gazette, "Centerville residents facing eviction in the middle of a pandemic, but not without a fight," Salt Lake Tribune).

Single family houses.  After the Great Financial Crisis, when hundreds of thousands of houses went into foreclosure, large portfolios of scattered site single family houses were acquired by Wall Street investment firms.  

Over time they made great profits from renting the houses out and property value appreciation ("When Wall Street Is Your Landlord," Atlantic, "A $60 Billion Housing Grab by Wall Street," New York Times).

This also makes it harder for individuals to become homeowners, thereby reducing the quality of their household wealth portfolio.

New construction single family housing subdivisions for rental.  Investment firms are taking this to a new level, by building new subdivisions from the ground up, but only for rental ("Wall Street’s New Suburban Subdivision Is Full of Renters," Bloomberg).  

They're being pushed to do this, because they like the profits from rentals, but as the housing supply tightens it's harder for them to find good deals.
