which is easier to sell/rent Flats or multi floor TH style? 

Prorating the new flooring at 50%, they owe about $2000.  

Arlen - I'm told that it is pretty "hands off" as rental properties go, and I believe that for a couple reasons - very good reliable and clean tenants, and it's classified as a "luxury condo" for what that's worth. 

Can anyone recommend a carpet cleaning service in the Raleigh, Durham, Triangle area? 

Your main costs will be Property Tax, Property Insurance, Maintenance (small repairs, landscaping, pest control, etc), Capital Expenditures Reserve aka Cap Ex (money set aside for roof, HVAC, Flooring, etc), Vacancy, Property Management, and then any debt service you have on the property.

Let's just say it sounds really bad; my walkthroughs have always been great the place has been clean and in order, I have no complaints. 

The house is nice too, 3 bed 1 bath with HVAC, energy efficient windows, and hardwood flooring.

My single family I bought with a government insured loan had a 2X4 ladder to the second floor (no other stairs) limited counter space, no dishwasher, old stove, only a stand up shower, and bad flooring.

- Taking the worst house on the block and cleaning it up has been very satisfying. 

You go down to county building and zoning on Jog rd, 2nd floor.
