Hi Dan,

I commute every day in Houston, but from the west side to just north of downtown, so I can't comment on the IAH area. You'll do fine with the summer after an adjustment period. It is not unbearable. Give it time. You'll adapt much quicker by being outside than those that stay in the A/C all day. You'll love the winter!

It's been a long time since I was in an apartment. I've never heard of a "maximum income restriction."

Welcome to Houston. You will eventually get a car.
