@Shadonna N. there is a Whole Foods in PG County near Hyattsville in "Riverdale Park" https://www.wholefoodsmarket.com/stores/riverdalep... and it has been open for nearly a year. We've eaten at the hot bar and it has the usual WF stuff, flowers, sushi, bread, pretty veggies, kumbucha and at least one pierced tattooed hippie dreadlocked staff member.
It's part of that development that is making Baltimore Ave... Route 1, a pain in the butt from a wee bit north of University Blvd down to the DC/ MD Eastern Ave border. There are new large developments, some spurred on by UMD-CP and other's EYA. I forget who is responsible for the Whole Foods on Baltimore Ave but there are more cookie cutter townhomes popping up behind the Whole Foods and all the other new establishments over there in that shopping center. In addition to a WF there is a Gold's Gym and some bar and grill I've never heard of, and a pizza place.... like the area needs one more stinking pizza place.
Since @Karelyn Cruz mentioned she was car-less let's focus on the areas that have MARC, WMATA bus & subway and have bike paths and semi-functional sidewalks. Parts of PG have that, but not all parts. PG is not MoCo, but that's why it is more affordable than MoCo.
There is a useful blog I've been semi-following Congress Heights on the Rise ( https://www.congressheightsontherise.com/index ) and she has a real estate section. Compared to hotter parts of DC the units she features are very affordable, but they tend to be condos, which the OP wanted to avoid. Yes, DC has the school choice option, but it is a gamble, a literal gamble. In 2 years I'll be playing that lottery. Former neighbors have played and lost, and that's why they are former neighbors (we live in NW DC, east of the Park). And yes, there are some great programs run by the city. Check out the DC Housing Finance website- http://www.dchfa.org/ a zillion years ago I got my 1st home loan from them at below market rates.
Yes, @Russell Brazil is an awesome and knowledgeable guy.
