Hmmm. I can't recall the names of all the streets, they branch off of the Crofton Parkway, which is a bit of a misnomer. The "parkway" is actually a residential loop with sidewalks that people jog, bike, run on. I think the speed limit is 25 mph. Anyway, find a map of Crofton and you'll clearly see a triangle formed by Rt 3, Rt 450, and Rt 424. Everything inside that Triangle is considered the Crofton Triangle.
There is a mix of townhouses and single family homes. I went over to a real estate website and looked at the homes for sale that I know for sure are in the Triangle and they started around $550,000. However, I did see one listed by an agent that is off Eton Way (clearly in the Triangle and considered "desirable" b/c of proximity to golfcourse) for $479,900. Not sure why its so much lower than other houses. Again, just my completely unofficial guesstimate. I don't know about the townhomes in the Triangle--haven't seen any for sale for awhile.
I haven't noticed any for sale by owner, but that doesn't mean they aren't out there. The local paper is capitalonline.com. Technically Annapolis, but covers Crofton neighborhoods as well so maybe there are some FSBO's listed there. Also, a local magazine started by a realestate agent called Suburban scene that has lots of local info.
