@David Edgerton , we have a friend who owns a couple of rentals in the Pasadena/Deer Park area, and he likes it for similar reasons. Deer Park is definitely a better school district than Pasadena, so a home there would be worth paying a bit more for.
We are looking into the Sagemont area (west of I-45, just south of Beltway 8 south). It's also in Pasadena Independent School District. It's not that it's a gem of a neighborhood, but we've chosen that area because my husband and I both grew up there, and my father-in-law still lives there. So, at least we know some things about the area.
The Sagemont area is comprised of several separate subdivisions (Sagemont, Sagemeadow, Sageglen, and a few others). Just recently my father-in-law mentioned that if we look at houses in the actual Sagemont subdivision, we need to be careful because those houses have aluminum wiring, and that's why they've had a number of house fires there over the years. Good to know!
