FNMA maintains a guide as to what types of homeowners associations they will invest loans in;
thus banks follow this in order to transition the loans they make to them as an investor. But FNMA wants limits on things like the amount of commercial space. Seems that apartment owners who live in their unit are the best risks. Even though commercial rents may minimize common charges in certain properties, I suggest that we all learn from FNMA's experience as we don't want to be in a property with a large amount of commercial space.
