I am looking for tax delinquent properties (Selected Tax - Yes under Distressed) Now, for the first 7 leads in the list, I went and looked them up in the county property taxes website and only 2 of them haven't paid their taxes yet.

I would suggest you first look up the listing on the city website, phila.gov.

I know about the Utah county website and I can find the owner name but have no idea how to contact them.  

Many counties offer a template on their website you can use.

We get e-mails from ORRA advertising sometimes about new events and if you have registered with a builder either at a home site or on their website they will email notifications about new events as well. 

You'd probably be best posting this in the real estate agent forum or visiting the NARPM Website and finding a local PMP. 

Be sure to check out the forums, the blogs, podcasts as well as other parts of this amazing website and like minded community.

They will also integrate the website that you currently have and whenever somebody does send you that email to get in contact with you, they have the ability to directly inform you but also place the information of the potential motivated seller in the data base for you.

Why not go to your bank and look into financing, or search the forums here around FHA loans that allow you to purchase with as little as 3.5% down while living in one of the units for a year.Also, use the calculators here on the website to make sure your numbers pan out and work for you.

Lance Hull is the guy to speak to over there.There was a webinar on this topic from the Mobile Home University website - recommend you check it out.
