I don’t think you could buy a similar property in the area, build two new churches of like size and caliber and get it all done for 30 million. Churches aren’t cheap to build and the land and design work is going to eat up about 7.5 of the 30. That leaves about a little over 11 per building — nope, not a good deal.
We looked into moving an old family plantation house from rural middle Georgia to Atlanta. The cost was absolutely prohibitive - we built an architect-designed, custom built home for less than a quarter of what it would have cost to move a single-story, wood frame structure to the site.
