Say I'm able to complete the refinance, I would then like to immediately apply for a pre-approval with the intention of buying another property as an owner occupant via FHA financing as my family size will be increasing in 6 weeks and I will need more square footage in my living space.Is this something I could do? 

Howdy @Eric DavenportAlthough some experienced investors may start with square footage or even the pictures, most go from a thorough walkthrough of the property.  

Who are the best commercial real estate property managers in Charlotte (think large square footage: schools, warehouses, condos, malls, Etc)?

@Jorge De JesusYou should ask for a breakdown of each of the 14 units(square footage and bed/bath information)You should do your due diligence with an agent to see how much each unit will rent for approximately. 

These days there will often be a map, where you can either click on the property of interest, or enter the address, and get a basic report - whose name is on the property tax records, how much the property tax is, the square footage, year built, etc. 

I would be surprised if you are able to get rents above $1600 there based on your square footage.

My tax person splits it 50/50 due to sq footage. 

Sq footage of concrete probably totals around 1k and my husband is able to complete the work himself, so costs would only be for dump and materials.

They want $375k, which is laughable, as a recent comp with the sq. footage fixed up and with a pool is like 425k..I offered $200k, quick close as is, but with inspection contingency... agent responds that they owe more than that, no point in countering. 

Do appraisers price in these circumstances or do they only care about the selling price, square footage, lot size, and number of units?
