EMF may not be done acquiring stations in/near Boston.
I'm sure they want their "Air 1" network to be on an analog FM signal in Boston. And they may want another station with a big signal to broadcast "K-Love" in southeastern Massachusetts and especially Cape Cod.
I could see EMF having interest in WXRV-92.5 (which has boosters and translators to improve reception south of Boston) to become "Air-1" and bring that format onto analog FM radio in Boston.
I can also see EMF being interested in buying WPLM-99.1 in Plymouth to give "K-Love" a strong signal in coastal Plymouth County, Cape Cod, and the islands, areas not reached at all by WBOQ (and look for those call letters to change very soon!) and not reached well by WKVB-107.3.
In fact, I believe EMF purchased the three or four other stations formerly under the same ownership as WXRV, which used to simulcast WXRV to northern Worcester country and New Hampshire, converting them to "K-Love", so it wouldn't be entirely "out of the blue" were EMF to buy WXRV to run "Air-1".
Another possible noncommercial purchaser of WPLM might be WGBH, to give their WCRB all-classical format a stronger signal south of Boston, in southeastern Massachusetts, and Cape Cod.
EMF (or any noncommercial broadcaster) buying a couple of more local stations would actually be "salvation" (pardon the pun!) for the remaining commercial radio stations in the market. With fewer commercial stations, the remaining commercial stations might get more revenues since there will be fewer competitors out there to sell commercial time.
