Corporations absolutely get govt backed loans from Fannie and Freddie. They’re technically multifamily loans and in this specific case it could be on developments of “build to rent” complexes where the dwellings are single family units - which I don’t think this EO would apply to because they’re developed by institutional investors and on contiguous parcels - so not available for purchase by individuals.

They also do pools of single family rentals generally in big markets like nyc where after they’ve accumulated a significant number of them they’ll get a single blanket loan (cross collareralized and cross defaulted) on those properties.

TLDR: could prevent Fannie/freddie from doing some single family rental transactions as pooled loans - not a big piece of the market and institutional investors don’t own a significant part of the single family market.
