Your unit should have some sort of laminate floors, ceramic tile and there is some beautiful rubber-type flooring that looks like laminate flooring and this stuff is beautiful and looks like it is indestructable.You have to clean the stove, refrigerator ant bathtub in every unit even when the tenants leave your unit looking spotless because you can't expect your tenants to leave a unit clean and sanitary like a professional cleaning service does.As I just wrote in a recent post, when I sold my 20 properties in Las Vegas last year my wife spent as much as two days cleaning one stove (JUST THE STOVE) and the stove was still filthy.

An older building may have growing infrastructure maintenance and replacement needs for systems such as sanitary sewer lines, water, electric, etc.

@Brandon G.Here is a "back of a napkin analysis":Gross rent: $1395*12 = $16740Less vacancy (8%): effective projected gross rent: $15400Less taxes, insurance, PM (10%), etc. : $15400 - $7164 = $8246Say you financed 100K @4.5%.

I hadn’t planned on doing multifamily so early but the napkin math quickly caught my attention.

Also, make sure that they don't have a "lease" written on a napkin.

Don't do anything on a handshake or napkin agreement. 

The reason for this is because running some napkin numbers it appears to cash-flow way better than anything in Florida (which doesn't really at all).My question is as far as getting a loan goes, how difficult would that process be to accomplish with two people?

Some of them can't even fold a napkin to save their lives.

@Labraysha Brickhouse You can use Zillow to find comps for back of napkin calculations, but it will be the least indicative of market value as it won't have complete data, but is often good enough as long as you don't use the Zestimate.  

How big of an issue is this and could it trigger the private sanitary system inspection contingency?
