Nearly same population overall and that is where the demo sameness ends. 

Almost finished with demo and mold treatment.

So if you have a contractor that can do the demo or painter to do Kilz or what not at a cheaper rate, you can deduct those from the estimate.

I'm trying to think about what would increase my profit margin the most and wanted a sounding board.Market rent in the area for my 1bdrms is probably somewhere between $550-600.My 3 bedroom is currently rented at $1300, but I think it's under market, and should probably be between $1350-1500.The options I'm toying with are converting the gutted space into a 5th 1 bdrm apartment to add ~$600 a month to income, OR, I can demo the apartment next to the gutted space, and turn both areas into a 3bdrm apartment for $1350+ a month.  

Welcome to BP @Jerry Yang!

The owner said he would not sell to them because they would just demo everything and let it grow up.

The demo is complete, new windows, new framing but there is nothing else so this is a clean slate job.

Demo existing flooring throughout residence and install new laminate flooring. ($3,800.00)Remove siding on exterior of house up to 4 runs high and reinstall new cement board siding.

In contrast tho looks like most of the demo work is done.

The structure is vacant and completely demoed.
