I'm a California-based investor who has just purchased and rehabbed a property in Tucson, Arizona. I studied the market for seven years and got a sense of what areas I'd buy in and where to avoid, and carefully considered the long-range view of the rental market as I intend to rent it out.
First, do not approach this lightly. So far, I've made one trip to scout out properties, and a second trip to renovate the property once I found one I liked.
Jon and Brian's advice is spot on. You really do need an extensive team of people including: 1) realtor you trust, 2) property manager, 3) handy man, 4) myriad contractors who will help you get the place into order for re-sale or to serve as a rental. I was fortunate that I lived in Tucson for ten years and have a decent network of friends who still live there.
Once I acquired the property on July 18th, I had to hit the ground running to get the following done: 1) roof replacement, 2) HVAC upgrade to A/C, 3) painting and restoration of interior, 4) electrical work to bring it up to code, 5) tons of work around the yard, fixing doors, windows, etc., 6) plumbing drain scope, etc, 7) floors restored as original concrete.
I did most of the above in four days, but it was intense. It has been a non-stop project ever since. The property manager visited today, and reported a whole list of additional items that need to be considered (thankfully most are minor).
It is not a trivial manner to put hard earned money into an out-of-state property. If the property is priced cheaply, there is a reason for it!
I've received an enormous, expansive education on the care and feeding of SFH's in the past three weeks.
Real estate is anything but a 'passive investment.' If I do this again, no doubt I'll be wiser for the experience.
My plan now is to rent this one property out for 12 months, then look at the numbers closely before I make any additional investments.
One other note: It is a really great feeling to own the deed to a property outright without a lien holder! Now, I'm awaiting getting a renter in place and the first rent check. Enough checks going in the other direction!
Good luck!
