Atlantic article cites 3 neighborhoods with low ownership in Cleveland/Baltimore as evidence for how PE is making home ownership unobtainable. It doesn't say the median price of a house in those areas is $120-170k. Home ownership isn't low in those areas bc investors are buying up all the houses but bc individuals who have the credit worthiness and financial stability to get a mortgage generally prefer to live in other neighborhoods.
The high rental price vs sales price in those neighborhoods is not bc big corporations are making outsized profits. Rents there have higher cap rates bc, relative to more expensive houses, (1) there are more unpaid rents (2) it is difficult and expensive to evict a tenant who is not paying and (3) tenants are more likely to damage the unit. Publicly traded corps that own and rent houses typically own middle class homes, not lower-income.
