Heard there's a nice air force base there.

If it goes out you yank it out and install new like a window air conditioner.For our area these rents were a little low but not by much.

Needs a new kitchen, two new bathrooms, flooring, some drywall replacement, window a/c units (possibly central air), etc.I'm looking to have this completed within a 2-3 week period once the work is commenced and would be available to meet onsite this coming weekend for estimating purposes.

People get cancer from the sun and still rub chemicals all over their body to prevent it.

By doing this will a future lender see this as an added debt against my income and prevent me from qualifying for a conventional and or FHA loan?

I guess the prevention for that is not to do it unless you can make the payments regardless of how the investment turns out.

Having two other mortgaged properties will not prevent you from finding a lender who will refinance your free and clear investment property. 

Brief background, I own a top/bottom duplex in Pittsburgh and am looking to get two, separate air condensers installed for the top and bottom unit.

Something that we use to prevent disputes is an Itemized List of Common Deposit Deductions.

Obviously, you need these utilities running as soon as possible to prevent possible delays.
