Buying lower end homes in a neighborhood becoming higher end

[Max L. Horton]

I found a neighborhood near where I live that has homes ranging from 190k to 500k+. The higher priced homes are new, close to “McMansions” (large house, 4 or 5 car garage, etc.). The lower end houses are the original homes that were built in the 1970s (4+ bedrooms, nice size lot and wooded, great schools).

My question is there any major advantage or disadvantage to investing in a place like this? What does this trend indicate for said neighborhood?
