I think using a combination of census data (down to the census tract level, which is often just a single neighborhood or a portion thereof) and school rankings makes the most sense.

There are 8 duplexes on this tract and they were built in the 30's and 40's and had tenants in it ever since.

Purchase price: $155,000 Cash invested: $40,000 5 acre tract with 1 4/2 single family, 1 3/2 mobile home and 1 2/2 mobile home.

Near term goal: hoping to digest as much of the material on BP as I can and network. 

Now, instead of any development, I'm going to sell off another 5 acre tract and will be left with the remaining 5 acre tract and a custom home with an extremely low basis.

same here for estate planning. my mom is the GP with me adding about half of my assets.we have no cash flow ranch land and producing minerals mostly, dividing into smaller tracts and owner financing. using the cash flow to acquire cash flowing investments in east texas and san antonio.mom is the silent majority.

It's somewhat useful in a condo development or tract home development where the homes are essentially identical - but it still doesn't account for upgrades.   

I've read quite a few of the books but having a group of individuals to digest the material with can be beneficial. 

Look at Blackstone the hedge fund and others buy up tracts and 1000's of homes just to turn around and rent to those same people that got evicted its a broken system.

Thanks for all the info to digest!
