I answered another of your questions this morning as well. Yes, Speedway is one of the main roads in Tucson. That is a nice area, but Speedway is a major street here in Tucson.
I strongly suggest you work with a local Realtor, I have helped many from out of state and out of the country make a purchase. If you can, would be best if you can time a trip here, never a good idea to buy something as inportant as Real Estate sight unseen.
Kindly click on my profile, give me a call or email. Even if it is not me, will be in your best interest to work with an experienced local Realtor to help you find what you are looking for.
To correct a statement on here, MOST of the time there is no cost to use a Realtor. Some agents do charge a retainer fee, or if you buy a non MLS there can be a charge, wanted to correct that statement to properly set your expectations.
I wish you the best of luck.
