A developer purchased a large tract of farm land I was connected through another brokerage that he was selling multiple lots.

If you want you can check out rentfaxpro for a low cost report on the location down to the census tract level data.

Even the largest 4 builders in columbus hardly sell any new inventory less than that. the smallest footprint that most of the tract builders build here is around 1500 sq ft.

Looking for someone that  is attentive and/or a company that tracts work, well versed in real estate, contracts, etc. 

Buying right is buying a home in an inner tract, not with a funky layout, buy a home that has great curb appeal (some do not even after tons of work), and the list goes on.

I would like to build multiple units on one tract of land (in county, no deed restrictions) but not sure how to approach it from the financing side.

4 months seems like a long time to be under CO tract and to not have all the repairs done correctly to the city's code.Additional questions:1) besides the 6% sellers concession, is there any more concessions I could ask to get out of the deal?

Back to the 50k foot view, if anyone wants to see a current example of (arguably) actual redlining at the federal level, check this out: mortgage product availability by census tract, direct from fanniemae.com.

I moved out of that state but due to the insanely low rate (and the fact I rented out my side of the duplex and am now cashflowing a grand a month) it makes zero sense for me to sell unless someone came to me with a stupid offer, which is unlikely as they would have to be a cash buyer and I'm content holding as my refinance went from a 30 year FHA down to a 15 year and it's a great property and was custom built and not a junky tract duplex. 

Here in the SE it's common for people to lease large tracts of land from the timber/paper companies such as Mead, Weyerhouser, Georgia Pacific, etc.
