Depends what you mean my strong? Strong rents, strong renter base, strong longevity of renters?
ASU and Tempe is a very strong rental area in terms of demand, but short term renters as students move on. Less mature renter base. Sun City has retired base and longer term renters that take good care of the property. North Central Phoenix is close to freeway access.Dense population and families. Central Phoenix corridor along I17 has high rental demand because rents are low. People move on.
Rental demand overall is good thoughout the metro area. Rents are on the increase. The possible exceptions are the perimeter cities, although even thiese get there fair share of winter visitor renters.
Scottsdale and PV are always popular and the rents are higher than in west Phoenix.
