Running comps this way doesn't take into account updated kitchen and bathrooms, finishes such as hardwood floors/granite counter tops/stainless steel appliances or amenities such as pools and fireplaces, etc.The best way to get a comp is to look at what recently sold within a 1-2 mile radius of the property you're looking at.  

There is a substantial difference between vinyl, formica and standard appliances and granite, tile and stainless steel among other things.

Video cameras and notepads are welcomed, as well as steel toe boots, gloves, goggles, and facemask....lol....really though.

I used Philip Beggs with Moore Ingram Johnson & Steele, LLP in Marietta GA. 

Not in the hood, I had a couple of long steel poles installed like is used in fence and had vandal proof cameras and metal halide lights installed on the poles with the lights.

That means bringing all electrical up to code and it may be worth more than what you can sell the house for depending on the location.If they are pumping water out of the basement - it could be a simple matter of putting in a $6,000 "waterproofing solution" (installing drainage tiles pointing water to a sump pump) to a $12,000+ repair of putting in structural steel to support a collapsing basement wall due to hydrostatic cracking occurring on the foundation.I would tread lightly on this deal.

So, for a steel tank buried 20-30 years, there are a lot of opportunities for leaks.Same goes for oil leaking in basements or crawl spaces.

Once you fill those slots up, your can still use bank money using commercial loans.  

typically shingles will run you $20/bundle (3 per 100 sq ft or 1 Square) for lower end, install depends much on tear off and prep or shingle over and prep, we have opted for Steel when ever reasonable to do so, it costs about 10-20% more up front, but will out last me, and does not have Ice damming problems we see with regular shingles in the north. standard shingles, you can expect about 1/2-2/3 the stated warranty actual life span, so 40 year shingles will last about 20 years, but steel, even 40 year has been known to far exceed the 40 year warranty, I can typically get a roof done in steel with a 2 layer tear off, and steel installed for around $4-6K for a 13 Sq roof thats material, labor and disposal, I just has a 11 sq one does with dimensional shingles (steel wasnt practical) for $2,700 including tear off and disposal. keep in mind, the cheap guy may not be the best value, there are a lot of hacks out there, and anyone with a pitch fork, a hammer and a nail gun calls them self a roofer.
