It sounds like you may be looking for a CMA, Comparative Market Analysis, from an agent in that area who could pull comps from homes that have been similarly repaired and updated around the home in question whether those are homes to rent or to sell.
If you are trying to determine whether a house is a viable flip in an area for investment, again, you need to work with a real estate agent that can really guide you properly. Market value in Phoenix is very dependent on location and can comparable homes for ARV can vary dramatically depending on the subdivision.
Hope this helps and feel free to expand on your question, I know that any number of us would be happy to provide additional details.
