Tower mansions tend to go up or retain its value, depending on proximity to the train station and other factors. 

. -- for me, more important than anything, was a motivation factor.

One important factor is the condo eligible for fha/conventional financing. 

(e.g. contiguous)- Comprised of 4 parcels:P1 - 70 acres with 2250sqft 200yo house and 20yo barn.P2 - 35 acres with under conservation easement.P3 - 5 acre minor sub division home lotP4 - 5 acre minor sub division home lotSITUATION- Seller is 70yo and retiring in 2019- Seller has heIrs who are absent and uninterested in owning the property (will eventually sell inheritance)- Seller is a frIend and neighbor of the famIly- Seller (and our famIly) have preservation/non-development hopes for land in the neIghborhoodOUTCOMESFor the Sellers:- Immediate cash lump sum (property needs some work)- "Guaranteed" monthly/annual payments for deal term- Retain ownership and occupancy of real estate until they vacate- Seller retains ownership if buyer defaults- Continuity of neighborhood legacyFor the Buyers (us):- Acquire property rights- Fixed sale price- Known caretaker/occupant- Continuity of neighborhood legacyDEAL OPTIONS- $450-500k sale price- 10% down- 20 year term- 0% Interest- Land ContractThis seems like a good option to consider in terms of managing tax impacts to both parties, but at the cost of fewer “ownership rights” for both parties.- Seller FinancingThis seems like a good option to consider in terms of better “ownership rights” for both parties, but at the cost of trickier tax implications.

But given the future development right next door I'm not sure if it would be better to sell (take the money and run) or rent it out (pull out the equity to buy more real estate, cashflow a few hundred/month, and hope the building next door doesn't drop the value of my condo). 

I’m curious to know what pros and cons, pearls and pitfalls exist for 10-15 unit MFH deals that involve a collection of individual houses from one development... as opposed to the apartment building type of MFH.

@Emma BennettOur developers are aware of this bug and are working to fix it.

Before I get started, I should mention that my dad has developed and rehabilitated nearly a hundred affordable housing projects over the years. 

Nothing appeals to everyone, however among the following, my wife and I have a strong preference over the personal  'yuck' factor in of the other. 

So to be safe you should go to the Cobb county planning department and discuss any property you are considering buying with them to make sure it is permitted under current zoning.They likely also have a 'rule book' they go by that you can read if you're a geek like me :) In Floyd it's called the Unified Land Development Code.
