This wire story says that when the closed churches in Boston are sold off, they will be sold for big bucks after being converted to condos. I’m skeptical. I think the trendiness will quickly fade after the first few conversions. How many church-condos are people willing to buy? There’s got to be a limited market of people willing to buy such units.
On the other hand, I expect the rectories to quickly convert and sell. Most rectories over a certain age are very large buildings, built to house a half-dozen priests at least. Our own parish of immaculate Conception in Salem would make at least four very nice condos and eight smaller ones. (The pastor and I speculated on it once.) I expect that apart from the rectories, many of the churches will be torn down for new uses, unless of course certain towns go ahead with their punitive re-zoning plans , in which they will lie empty and unused, dragging down their neighborhoods as they decay.
