It depends on your zoning. Residential areas...no. You may be zoned rural, which is how people can have animals on their property.
PG county schools are, quite honestly, bad. We just moved from southern AA county, and I work in Upper Marlboro, and everyone we know in the area (which, after being there so many years, is quite a few folks) with any means sends their kids to private school or homeschools like us because the system there can't be trusted. My BFF is a product and won't send her kids there. I could not recommend PG county to anyone with kids.
It is about 1.5 hours to Columbia from where Maxcine99 is, though, not counting traffic. Probably not a great option for the folks asking about moving here. In rush, that would be a 2 hour commute. And yes, we know people who do that long of a commute regularly -- my husband has a coworker who lives in PA and commutes to Adelphi (he leaves his house at 4:30 am) -- it makes it hard to keep the place up in summer with the mowing.
We looked at al lot of those places in Waldorf and La Plata. Too much work for the amount of money they were asking. Many were in serious distress because the owners had no money to keep them up. In one place, the property was great, so great I went back three times, but they had ripped up the floor, obviously to replace it, and started some other renovations, and then ran out of money and walked out. It was so not move in ready. Most of the reasonably priced places were that way. It was discouraging, and while we aren't afraid of hard work, we had to be reasonable too -- 4 small kids, jobs, having to move the whole family, two and four leggeh d (we actually fenced what we bought ourselves and built the barn and coops) meant we couldn't take on a huge project before we could even move -- and a lot of them were not feasible as a result. Our lender also said flat out no to a couple of them that I liked as there would have been too much work, unless we had gotten a 203k loan (which is a pest because of the structure to prevent excessive spending).
Look at taxes too. I was OK with our taxes until someone told me what she pays in another state, and I pay way too much.
