@Anita Ahuja when I first was looking to branch out from California because rentals wouldn't cash flow any more back in '06, I settled on Indy from a referral of an investor-friend I had who had been successfully investing there for years. I purchased two properties, one of which I still own, and I've never been back to the property since. I don't feel a need to visit my rentals. Annually, I have my property manager perform an inspection and send me pictures, and that's all the verification I need the house is still standing ;)
Once you decide on a location, your first step will be finding a real estate agent. From there, they can usually hook you up with all the team members you'll need, like a lender, insurance broker, property manager, etc. (that's what I do for all my clients in Houston). Each subsequent vendor that you work with will also have referrals for you as well. Soon enough, you'll be able to find someone to do whatever it is you need in the new area.
My point is, I would not choose an area just so you can fly to it, because frankly, I think you're going to find you won't be doing that much, if at all, and your tenants certainly won't want you popping by all the time either.
As the years have gone by, one criteria I personally have developed is I don't like to invest in snow country. God forbid a tenant leaves in the middle of winter (had it happen once, broke the lease and bolted due to personal reasons). Took four months to get the house rented. No one wants to move over the winter. Longest winter of my investor life, and now I'd much prefer to buy somewhere that will have no chance of happening again.
