If you really are interested you can get a consultation from a real estate attorney for a relatively small fee.I do not know the disclosure laws in your area, but where I live, if the property owner has taken reasonable steps to fix the material defense and reasonably believes the problem has been address, then it does not have to be disclosed.

Flat roofs are expensive to get replaced and do work on.On a 10,000 sq ft pharmacy building cost to replace is about 20k to 25k all in.Some of the older membrane materials dry up and crack causing leaks.

I'll spare the details but the first crew whom I've worked with before and are proven, charged me $6,500 WITHOUT materials.  

@Troy Fisher I have seen your name many times as I have combed through Seattle related materials here on BP.

Between all these locations, we have found about another $1,000 to $1,500 in antiques and building materials that would be good in lower end rentals.Basically, with a little legwork, we should have no problem recouping about 8% to 10% of the purchase price of the home just by reselling the items contained within.Does anyone else regularly deploy this idea?

I'll plan to post every week or so with a progress report and any new material information.

Those are all great reading material and great motivation to get you started on the right track. 

There's hidden costs of extra miles on the car, business cards, website membership charges, business license, training materials, ect. so even on a shoestring you're going to need to budget.

You don't have to get permits but obviously you'd have to disclose that since it's a material fact.

I'm guessing you haven't listened to the Podcasts, blogs, or downloaded the free materials here on BP and other sites, or gone to some REIA's.
