So far so good, we listed with an agent who has extensive experience in rentals.

I mean are we talking a light plugged into a normal outlet or we talking a garage w/ stolen power and stripped extension cords that dims the neighborhood? 

Anything with extensive rehab needed to re position property up to 10M.

He now will not sign an extension, even though I agree to give him time to get the student loans taking care of .

One trick I found is that old rubber air hoses make for good tie down straps and that romex or extension cords can work well too in a pinch.Another is that getting into a house without a key is usually not that hard so I don't worry about keeping track of keys of properties I am not currently working on.

It's been fully renovated: new driveway, new interiors, extensive remodeling.

Although I have no magic crystal ball - On a gut jobDepending on how extensive you are guttingWindows/Electric/HVAC/Plumbing $45 - $65 per SF is a fair Guesstimate

If you can't find funding sometimes there is an extension. 

Maybe it's because I have extensive construction experience and I did things that even my subcontractors saw as over the top and the buyers won't even notice but it's the peace of mind that it was done right.

Will be done in 3.5 yrs. http://kcstreetcar.org/about-streetcar/mainstreet-extension/
