Contact a local closing attorney as they may have one for you to use. 

Is there a better way to contact the owners of these properties?

I contacted ALE solutions on Friday through their housing request form and just resubmitted with a longer term minimum based on what you stated here.

Quote from @Catherine Ashmead: Does anyone know of good companies in Arizona that I can contact?

Any contacts in setting a good team of contractors (general purpose) and cleaners? 

I really like the idea of leveraging local contacts for walkthroughs and feedback.

How is a text or call to a homeowner who is advertising their property for sale considered an unsolicited contact?

What is your preferred method of contact and when is a good time? 

@Paige Corsello...You could call your bank contacts and find out if they are broker friendly.
