@Matthew Kwong I would say my market (Phoenix/Scottsdale/Tempe market) due to low pricing and high returns.

The summer temps get up into the high 90's sometimes but the humidity is in the 20's so nothing like FL.

If you're also interested in Tempe, I have only been through a little of that, but from what I've heard, south Tempe seems to have a better reputation than the area around ASU (think students... and parties).

The town is a steadily growing one, but there are lots of temp construction-type workers that visit the area.  

I have been finding discounted homes in Phoenix, Scottsdale, Tempe, Chandler, Mesa and other parts of Metro Phoenix for a few years now.  

The landlord just put the house up on the market and has informed me that they will be putting a lock box on the front door as well as will be showing it several time within the next few weeks alone on top of that a couple months ago I gave him my rent check on the 2nd beacuse the 1st was a holiday and the banks were not open he proceeded to hassle me and tell me that my rent check needed to be there before the first and am always afraid to do that simply because i feel he will cash it to soon he did that with my deposit cashed it 2 weeks before my lease started i guess that should have been a sign however i also was not told that in order to keep all rooms at a consistent temp of 65 I need to keep the thermostat at 75 please help  any way out or am I on the hook?

Two in Glendale and one in tempe.

Let me further assume that the units are each getting the Tempe market average of $992/mo/unit.  

My temp job/internship just ended so now I'm unemployed.

Having acquired my first fourplex I got hungrier to acquiring more properties but I didn't know how to so the same thing that's happening to you happened to me, I started seeing "bandit signs" which advertise "Mentor seeking trainee" everywhere where I drove by, Chandler, Ahuatukee, Tempe, Gilbert, South Phoenix, I mean everywhere.
