Contractors pickup materials, not you.

NJRS §45:15-16.46(b) Any person who violates any provision of this act or any person who, in an application for registration filed with the commission, makes any untrue statement of a material fact or omits to state a material fact shall be fined not less than $250, nor more than $50,000, per violation.

Mindy Jensen Yeah the older materials were terrible at letting water escape and you would tend to have a lot of moisture issues.

Please read the fine print with whoever you decide, get a solid materials in place and warranty as well.Thanks,MH

@Jorge Ruiz True, the neighbor house put in very basic materials for their rehab, carpets in the bedroom and basic laminate flooring throughout.

I hope to use wealth of material found here at Bigger Pockets to help me get started successfully investing in real estate!

I can't speak on how demo is done in certain states but from what I could tell you being a license contractor here in NY and you being in NJ which should not be much difference is do the following steps.1- have them demo and take everything plumbing and electric.2- the only scrap metal you should keep is copper, but also negotiate with the demo grew to reduce some cost if they want the copper, all other scrap metals are not word it.3- has for the electric, just have them leave you 2 plugs because that's all you need until you update all your electrical. mostly all power tools are cordless so I doubt you will blow a fuse and you don't need any light because you work will be done during the day.ALSO NOTE: do not have anybody mess/touch/remove with any electrical panel or any electrical box, leave that for a license electrician to do because thats a big safety issue that could bring a lawsuit if a non-license electrician gets any injury for attempting to do so.

Also, this house had a huge metal roof.  

I merely want to know about reference materials on this subject and is my idea doable? 

Since you say you & your husband are just getting started you will find this site to have a ton of material you can gain knowledge from in many different formats like webinars, podcasts, blogs, forums, articles, and books.
