It would be a shame to see the church torn down but I could see it happening for infill housing on that lot. All of those areas around the Gathering Place will only continue to go up in value. I wish I already owned real estate in Maple Ridge and West Brookside.
It's a very nice looking church but without a buyer, that could be 16+ lots in a prime location by Brookside and the Gathering Place that could likely get ~$200k/lot or more (so $3.2 million excluding the 5 extra houses they own). The tax records say it is worth $2.8 million, but might be much larger and more valuable than what it says with addons/expansions.
It might be a toss up for them between demolishing and parting lots or selling the church to another church that might run into the same issues down the line. I'm sure the neighbors would prefer it be demolished and turned into housing. If houses similar to new ones going in for the neighborhood are built, that would add about $141,000/year in taxes (~$9.4 million taxable value including land). Big gain for Tulsa and the area schools.
Or some rich person could buy it and convert it into a massive house! I bet a creative architect could make it work. People have converted old churches to homes all over the world and it can look brilliant when done well.
