I'm currently soaking in the education material and working to establish a great network of real estate professional.

Are there any recommendations for contractors/builders that could provide an estimate/schedule and/or material list for similar work done. 

I have found the best way to control costs is to have a detailed material sku sheet.

Colorado mandates asbestos and lead testing before any type of suspect material is removed. i can answer any questions you have in regards to asbestos abatement and lead remediation. message me if you want to chat about possible solutions to the asbestos and lead issues id be glad to share my knowledge with you.  

I did my fairly large kitchen for about $50 in materials and it's held up great for two years of use.

As with any contract though, you'd need a very specific scope of work, material qualities, etc.

Now here is my two cents - a home's square footage is one thing to compare on a CMA, but there are other things too- updates, materials used etc.

Like a @Brian Burke for example who is a foreclosure expert in your market.. then there probably is not the kind of money in it your thinking there is.picking up the pieces of a failed major rehab can be all sorts of problems.. at least the foreclosure will wipe out material men liens in CA. 

It has been built with several different types of materials, and seems to be held together by caulking.  

You can find all the contractors you need -- just go to Lows or Home Depot 5:30 in the morning and talk to the folks buying material for their next job - negotiate Charles
