A roof could look tired but still function.It is easy to find out when a roof or furnace was installed and what its useful life is.

I had a basement that would flood, so we dug down a foot around the house 10 ft out where most was coming from, installed some 6mm plastic and back-filled with a nice grade away from the house and haven't had a problem since.  2 guys digging for 6 hours.  

He asked me if I would be interested in having him install granite counter tops in the kitchen.

You can get a new one for $600 installed.

One thing my broker brought up is that this may be considered a conflict of interest when it comes to the statement of identity that would have to be signed.The rehab budget is only going to be about $20-30k (walkthroughs for estimates next week) and I will be using subs for most of the work with the exception of some big ticket items like cabinet install and kitchen/bath tiling.

I'm wanting to install either hardwood  which i think is out of the question (nothing to nail it to) or engineered flooring. 

Options 2 – Upgrade electric, fix walls from electric installation, upgrade just what is needed, paint, floors, rent at market values.

I came across allure flooring from Home Depot and fell in love with the ease of installation and overall look.

Also free delivery and free install for dishwasher over $399.

Depending on location, what the foam is made out of (polyurethane is most common, I believe), other characteristics of the foam (R-value, whether it's water soluble, etc) and how difficult it is to install (are the cavities open or will the foam need to be injected through walls, etc) will determine the cost, but you're probably looking in the $2-5 per square foot (of cavity space) range.
