There are two sets of hedarim, one Chabad and one started by the Chassidsh Kollel (how that will develop is unknown as it is quite new). “Totah Institute” was founded by a hasid but is now dominated by yeshivsh.
In the heart of the frum community, houses under $250K are common, and if you look hard enough you could find a semi-detached for well under $200K. More expensive options abound, but they tend to be further away from the most-frum shuls.
Note you will probably need a car in Baltimore, unlike Brooklyn.
