@Samuel Gates - A number of years ago, our family went through this as well. The back story. I had purchased the property adjacent to my grandparents property. We tore it down, built new and sold it. When it came time to sell my grandparent's property, I suggested we tear it down, build new, and sell it. Based upon the market the property was worth "X", our construction costs would be "Y", and we could net an additional "X" in profit. To be clearer, if we sold "As Is", we would net "X". If we developed, we would yield "2X". In my mind, a home run, and it would benefit everyone in the family - grandparents, parents, and grandchildren.
Two problems: 1. all parents were not on board (felt it was too much risk), and 2. grandparents were offended that their property would be considered a tear down. In fact, my grandmother scolded me and punched my shoulder when I suggested we tear down the property. Fortunately, she was 90 so it didn't hurt : )
What really happened: After the discussion, the property was put on the market, and sold in one day - cash for "X". A developer bought it, tore it down, built new and sold it for the same value as I projected. What we discussed occured exactly as predicted except the family lost out on an additional "X" in value.
The real kicker is 5 years later, when we were talking about the market, and what had transpired with the property, my grandmother chimed in, "Why didn't we build and do it ourselves?" It took all that was in me, not to fall off my chair.
So the moral of the story. @Account Closed , and others make good points about zoning, experience, and working with a developer. Nevertheless, unless everyone in the family is on board, it will be hard to move forward. In our case, we were talking about an immediate sale. Managing a MF asset for a duration of time adds another level of complexity. Is it a good idea: sure. One that merits exploring. In our scenario, I didn't see the same risk as the others, because in my mind we had "X" value of margin to break even. If the property is held longer, risk and who the asset benefits can become more complex. For instance, who holds the note, is there a guarantee, who manages, is there a fee for managing, when do you pull out cash, or do you just cash flow the asset. These are the questions most family offices work through because as you get to different generations, the goals and objectives for the various family members begin to diverge.
Hope this story helps and if not a bit humorous for you!
