@Bruce Scannell you are on the right tract.

That way if you get roommate drama and one tenant moves out you do not have to tract them down, the remaining 3 are still responsible for the 1300. 

So I saw this post a few days ago and have been digesting it.

it took me months to digest the stuff there.

Again, in Allegheny County there's a remarkable tendency to talk about the larger neighborhoods of Pittsburgh into homogeneous units and even turn large municipalities into easily-digestible chunks of sameness, it's not the truth.

So much depends on type of development (tract vs infill) and price point.Raw land could be under 5% on  a suburban tract development, and well north of 30% for Atlanta's top neighborhoods on infill deal.

These tract homes, or more or less customs? 

Jay's model of "I will give you your full asking price"  but letting the owner carry the contract with no interests is smart and makes the play digestible.

Is it enough to simply zip up the folder and send it off, or is there some expectation of bundling it all in a more digestible format?

The model is also based on the fact that you are purchasing the house in the middle phase of a tract, so that when your house is completed, the home builder is still selling houses.
