There has been lots of good advice so far. I hope to add a bit of my own. If it was my money, I would consider Queen Creek communities of Cortina, Sossoman Estates, and Remington Heights. WHAT, Queen Creek, I must be insane!!!! Two of these communities share a border with Gilbert and are right across the street from Power Ranch (a community I am very fond of)... The great thing is homes with a Queen Creek address demand a lower price. I know Cortina and Sossoman Estates share the same schools as Power Ranch (Higley Unified School District). With these communities you can get the best of both worlds, Higley school district and Gilbert location all at better prices.
As always, buying correctly is an (the most) important part of the equation. Find the best deals, then negotiate from there. Also, know I currently own investment properties in Gilbert and am forming an investment LLC in the next 3 weeks and will actively be seeking out the best deals. I know I will find more deals than I can initially handle. Feel free to contact me if you would like to be notified of the excess deals and maybe we can do something together..
