Banner Health, the largest hospital system in Arizona, just bought land in Laveen to build a hospital plus a retail developer is building a new shopping center/outdoor mall.

It's great that you're balancing your passion for real estate with family time and outdoor adventures.

I was already considering putting up a wood or vinyl fence to create a decent outdoor space for my tenant but that will only block the sight in the back. 

-Sauna-Hot Tub-Patio/courtyard (large cement tiles on crushed bluestone with lighting, natural gas line to bbq)-Secondary patio off primary suite-Losing sq feet in the primary bedroom to enlarge the bathroom-High grade cabinets-Appliances with cabinet fronts-High end appliances (Viking/Miele instead of GE Cafe)-Outdoor shower (teak box walls with a dry well beneath the footprint)-Wiring for Cat6 to every room-Wiring for surround speakers (or including the speakers that are built into the walls)-Sonos whole-home audio system-Hardwired cameras (with on-site storage) to the exterior of the house-Smart features: thermostats are a given, but how about light fixtures, switches, aromatherapy, fans ... anything else?

Your tenant is more likely to experience issues from something outdoors.3.

The upside to associations is that you will be able to leave the property and know that there is someone managing the grounds outdoor maintenance etc. 

Properly sized domestic HVAC systems are designed to maintain a 20 degree difference between the indoor and outdoor air, but even that has limits.With an OAT (Outdoor Air Temp) of 114, the lowest indoor temp one can reasonably expect is 94.One can reasonably expect climate change to have an impact on sizing guidelines going forward.My $0.02 ...

I see many town home new builds have this feature but likely because it allows higher density/lower cost of land since many lack yard area but the rooftop allows an outdoor feature. 

The amenities and outdoor space are the bigger draw I have seen. 

The amenities rule everything (especially outdoor).
