I will just say that conventional/conforming mortgage rules are universal and you agreed to the terms.

I have been an agent for 18 years and have extensive experience processing short sales and Probates, and I am conformable with cold calling and door knocking. 

I am conformable with cold calls and door knocking. 

These loans conform to Fannie Mae or Freddie Mac standards.

If you have a non-standard sized rental say a 600 sqft place in an area where most rentals are 1100 sqft you will have a much harder time renting the unit since your rental doesn't conform to the major demographic, on the flip side its not competing in the same space (but you'll likely get less for it overall) - vs a 600 sqft unit in San Fransisco is considered a spacious apartment and will be competitive in that market for rent since there are a lot of single people and younger couples renting in that area and housing is limited. 

It was built as apartments at a campus bus stop but doesn't conform to the HUD's updated standards for Fair Housing Accessibility because all the doors to every bathroom are just 24" wide and cannot be made wider, so when they did their first major remodel, they sold all the units off as condos. 

Ordinary people are capable of atrocities because ordinary people aren't actually good, they merely have a kind of socially acceptable veneer of conformity, and if society goes mad, they will, too.I endorse strict rules, but not pointless rules.

Whether your home is an apartment or a house, keeping and maintaining it requires a certain amount of conformity to society, even if it's limited to just paying your property taxes.

@James S Tomaszewski that’s a good rate for a non conforming loan. 

That being said, that means the proper way to do this would be to get a commercial, i.e. non-residential loan, since a legal entity such as a LLC is not eligble for a conforming residential loan.
