Hi, Have you considered Hyattsville? It’s a great family neighborhood, still pretty affordable for the DC metro area. I just moved away because of my husbands’ job. The area around St. Jeromes church is great. There are many Catholic (and mostly homeschooling) families. There are great houses, parks etc. But really it it a fantastic and very close catholic community. Just go to the parish and talk to the pastor. GOOD LUCK!
