We got a full remodel, rents were paid the whole time and during the process we actually made some changes like adding over head lighting and outlets.

Electrical would be minimal when the work is done but the rental unit is empty because you're likely talking about a frig plugged in and porch lights on at night (and perhaps a light or two inside on a timer) to give the impression someone lives there for security reasons. 

Demo of old roofs (3-4 in place now), replace rotting wood planks as needed, light siding work, seal up old chimney & skylights, replace gutters/downspouts, and install new roof covering? 

They had a both at last years Noteworthy conference and the pitch there was assistance in determining if a borrower had assets worth pursuing in the collection of deficiency judgments.Another thought, I suspect that @Dave Van Hornmay be able to shed some additional light here as well.

I'm trying to find a deal that I can lightly rehab and build some equity into.

Items such as hardware, outlet covers, light fixtures, caulking, window blinds, painting supplies, etc.

The age of the home suggests that it was not built to handle the extra weight.

You need understand the market dynamics and to recognize that there are multiple metrics that can contribute to your final decision about a particular property -- and that some may carry more weight than others.
