There are a lot of sources for information out there. First and foremost, I suggest building a relationship with a Realtor who can personally guide you through the process and answer any questions and setup showings. Please take a look at my profile and reviews from past clients. I hope to talk with you soon!

If you have additional questions please call
Which house would you like information on? Are you looking to rent, or buy? If you are considering buying here in Tucson, I would recommend you first get pre-approved with a lender. Next, find a local Realtor and start a relationship with them.
If you are looking to rent, there is a company called Apartment Locators that can help you find a property to rent that meet your search criteria.
In the future, if you have a question about a specific property, you may find better results if you include the property address, link, or MLS number.
Best of luck.
