If your requested rent does not include utilities, the HA will guesstimate the utility expense based on many things such as the age, size, number of exposed walls, heat source, appliances, household size,       etc.  

However; you didn't mention the size of the lot, therefore; the fact that it's zoned R3 doesn't necessarily mean that it works for that purpose. 

. - Rebuild Cost $174,000 - Annual Premium $387 - Owned in personal name - Row homeProperty 2 - Built 1921 - 4 Bed - 2.0 Bath - 1750 sqft - Rebuilt Cost $335,000 - Annual Premium $627 - Owned in LLC - All brick single family with detatched garageProperty 3 - Built 1910 - 3 bed - 1.0 Bath - 1300 sqft - Rebuild Cost $344,000 - Annual Premium $734 - Owned in LLC - Row homeOther than some obvious difference in size and age and ownership entity...The rebuilt costs that USAA are using seem all over as are the premiums.

I try not to provide this unless the set up makes it difficult/impossible for someone else to bring in their own, i.e. it requires stackables, apartment-size only, under counter design, etc.

A foreclosure property may miss a door or window but properties just don't mysteriously shrink in size because they are in foreclosure. 

I'm looking at a few properties that are much bigger in size, but have no experience buying them so am trying to research commercial loans. 

The size of the loan cannot exceed your  (or your and your partners) networth and you have to have 10% of the loan amount liquid after the closing. 

You will start seeing a range/bracket for the different sized units and most likely they will also have pictures so you can rate the quality of the unit along with the rent. 

I know the size of park will be a factor but in your experience give me an example.

@Bhai Shah what size is your deal?
