(Note 1) I couldn't find a match to indexed descriptions, which most likely means the parcel was subdivided (e.g. description says 29.035 ACRES and becomes 1A lots) or combined (e.g. 2 TRACTS becomes 10.65 ACRES)

I must re-read this a few more times to digest!

While this is not an earth shattering revelation, it does warrant slowing the puck down and revalidating the other information you have ... there is nothing wrong with insisting on an extension to digest this new information and decide whether you wish to proceed.Since you will be looking at ~$1500/yr less revenue than anticipated, you could propose to reduce the purchase price by $1500 to offset the oversight on the part of the Vendor.

and that's just gas.On the flip side, you can hire a K&B superintendent for probably less than a $100K/year, get him his GC license, and he can manage 100+ home tracts and get dozens of homes completed every month.

Quote from @Christopher Teal: Hi Christopher,Here is a mockup of SFH's at the density of the close tract in the picture.You may have drainage issues that take up valuable building space for ponds and swales and etc..The feeder road into the place looks like it's small and not well traveled.I put in a kids play park, to give the tract some sales appeal, plus the area seems to me not best for housing.Look at the width of the feeder road into the other tract and look at it superimposed onto the country road.Do you have city water, sewer and elecric in enough capacity to build as much as you want. 

Lots to digest

I agree that there is a lot to digest in my question, but I appreciate you attempting to answer to the best of your ability. 

I am still digesting and will have to do closer read through your website.

You can pull lists with them and they will skip tract them for you.

·In about 30 days, I began selling the now subdivided land in 40-acre tracts.
