There are a bunch of ways to do this depending on the property type, usage, and you (income and credit scores).If this is a primary residence, you can get up to 90% of the value of your home minus any exisitng debt. 

It will only appraise based on comps of similar residential properties.

Are they doing everything possible to expose properties to the broadest possible market?

Wondering also if there are lenders that would have an appetite for this type of property?

This ensures you have a proof of concept to show the commercial appraiser.  

Quote from @John Warren: @Mordechai Chaimovitz cap rates and NOI are commercial real estate terms, and 1-4 units are not really valued in the same way.

I have flipped multiple properties mostly land and SFH.

Why hasn't your property manager already answered this question?

Luckily mine was zoned commercial and so the regulation didn't effect me and actually helped as it greatly reduced the supply in the market. 

My plan would be to keep the front waiting room as a small commercial space and the back offices as efficiency units or studios.
