I live in Southampton and have lived here for over 30 years. It is a great town and doesn't have a lot of "turn-over'. With the criteria that you requested the least expensive single home is asking $304,900. There is one with only 2 baths, and that is asking $299,000. There are currently 24 homes for sale with the criteria you requested and the price can go as high as $700,000. But the average price would be around $400,000 asking. It would depend, mostly on the age of the home.
Are you inquiring about Southampton for the school district or the area? There are numerous towns adjacent to Southampton. Some are in the same school district and others are different school districts, but still adjacent. to Southampton. The are located in 2 different townships. One is Lower Southampton township and the other is Upper Southampton township. The mailing address of Southampton, PA. is locatated in the Upper Southampton Township. I know this is all very confusing. Feel free to call me at 800-339-5834 and I'd be glad to explain it better and you can also receive an emal of all the listed homes that meet your needs. Hope I was able to address your questions,
