Way to Go Daniel, You Nailed IT.

That being said, each nails and bolts in your second hand home has appreciated a lot already. 

When I find my deals I'm fighting tooth and nail to get, and close them.

@Husnain ShahidI would look into this article b/c they nail it on the head with conversational marketing.You'll need this if you already have your own website.I like to build my own sites so I'll be using these same SEO techniques myself...https://oncarrot.com/conversation-marketing-how-to...

He also said there are 4 broken windows, all interior doors have been removed and a couple of them were nailed to the wall to cover the busted windows, and a couch was half way out another window.

Although I'm not a builder or a construction guy, it seems that when the house is built, the frame is put up, then plywood is nailed to the outside of the frame, then, a vapor barrier is put on outside the frame and plywood, then, outside walls (commonly brick, sometimes something else (stucco for example).But, once the house is already constructed, the ones I'm looking at that have been stripped inside, it seems difficult to replace the plywood and vapor barrier between the frame and the brick.Any suggestions?

That is an expense that I can nail down hard in all cases.

Know that you're going to get a few scars and break a few nails for those hard won lessons (I broke 4 nails yesterday - it was a good day).  

Can try small claim court showing your medical bills because of frost bite, cold having no heat, weight loss having no kitchen to cook and fungus body.

I would say you nailed it...but I would be wrong.
