There are a few more cosmetic issues that I'll need to deal with, but probably no more than $500 worth of materials and labor. 

Is it customary to ask your GC for an itemized list with receipts of all materials?

If you got a good appraisal and were to leave the appraisal with your marketing materials, that should help.Now, know that the appraisal you pay for will never be used by the buyer's lender. 

Great stuff so far, tons of terms to understand but I love how Marty goes over material that will be on our test.

I get keeping track of the material costs, etc, for tax purposes, but what about my labor costs.  

Builders warranty is also something that looks great for an investor. 1 year covers materials and workmanship2 year coverage on all mechanical/ electrical and plumbing 5 year leak protection internal or exterior infiltration 10 year structural Love to hear thoughts on buying new construction?

This is most likely higher than it will cost, as a good plumber will be in and out with that in less than a day, and his parts and material wouldn't be terribly expensive.

I am currently studying for my brokers license in Colorado and am about a quarter of the way through the material.

The listing agent (at least in WA so I can only assume elsewhere...) cannot withhold knowledge of a material defect, well, they can, but they could be held liable later by a court and/or their MLS.

The materials and finishes are a bit different in the U.K.
