Requirements to me seem simple:
– good school district
– 4+ bedrooms
– 3,500 SF or greater
– about a $1M
– newer home / modern style
– nice area
– not too much street noise
– move in condition, no renovations needed

Not to be taken into consideration:
– high HOA/MR/CFD costs
– commute (as he’ll be working from home)
– large yard not necessary

Good luck in your search! Seems like you have done a fair amount of research and should be armed and ready for your trip out next month!
