I'm not sure whether you may have already found something to fit your needs, but I wanted to make you aware of a great house I just listed that's located in the school district you want. The purchase price may be just a tad higher than 215,000, but I think it's within your range and I believe the owners would consider owner financing. Below is a link to this great house that's in fantastic condition and move-in ready!
