@Chris ClarkDid you review (IRC Sec.72(t)(2)(F)).The distribution may be taken to pay the qualified acquisition costs for a principal residence of a first-time homebuyer who is the IRA owner, the IRA owner’s spouse, or the IRA owner’s child, grandchild, or ancestor of the IRA owner or her spouse.The interpretation  is yes a duplex would also fall under this exception since it is your primary residence.The aggregate amount of IRA distributions taken by an IRA owner that may be treated as qualified first-time homebuyer distributions cannot exceed a lifetime limit of $10,000.first-time homebuyer.

I've selected GP Vision Pro D5 siding at retail list price is $6.28 a piece at Lowe's, or $0.63 a square foot.

I never set foot there. but I had been there in the early 80s for a convention on antiquated plats and how cities were going to deal with hundreds of thousands of lots that were platted and never built on.. and Lehigh is the poster child in the US for such subdivisions. 

Just NIMBYism.Cost per square foot depends on your level of finishes, density, and construction timeline.

Any other recommendations on how to get my foot in the door?
