If it is truly a B area I would not take section 8. 

Or get a nice one in a B class hood in the 300k range.

[8] Have you thought about offering non-refundable discounts for 4 duplexes, if % is paid pre-build--to give you some cash wiggle room for over runs.[9] Will you manage this out of an office, or just an onsite trailer.[10] Will this be an A,B,C or D neighborhood once it's rented up (what's the area like 3 miles or so around it--it will probably have the same renters.)[11] Is this Gentrification of a neighborhood?

Would recommend A-B stuff.

I would love to help you look into this a b Which area of Myrtle Beach is the property in (North Myrtle, Cherry Grove, Surfside)?

In recent times I replaced 3 unit’s cast iron with ABS and re-lined 4 unit’s cast iron piping.  

Ab stable.

A, b, C or D areas doesn't matter.

Will improve to a B.

(For a double close) You will sign the initial contract with the seller, the AB contract.
