I've linked the report below.

There are much straighter and lighter trees that grow faster available for dimensional lumber: firs, spruces, and various other pine species.The rafters are not the biggest issue here -- a sturdy rafter structure is to be expected in a pre-truss structure, where simple solid rafters in line hold up the roof, not a complicated structure of thinner sticks taking up lots of floor space in the attic.You need to look at the attic floor from below carefully.

The fact that you are considering this nonsense is disappointing as it suggests that your business judgment is below water.

If I find a buyer interested in purchasing all 5 contracts but only if the price could be lowered for each one, I could go back to the seller and lower the price for each one individually?

Even being about $150 below market, my ROE is about 8%.

Right now there are plenty of homes sold below asked price outside high paying employers Google, Linkekin, Tesla, and Facebook.

I own homes where you can walk 100 meters and the whole demographic changes.One basic rule is never go below $800 a month rent, We don't really look at anything under $900 to $950 these days. 

There was straight up gravel on that carpet.
