It is a good way to try someone out a couple of times with having the website as your fall back for any liability reasons. 

The property is located in Maryland so I checked the SDAT website for owner name and mailing address and no luck, the mailing address listed is the same as the property address. 

If you want convenience with the whole process you can use a site like Cozy.co.

Do a quick title search on the county recorder/auditor site

I went through the city code violation department to get a list of properties and used the tax assessor website to get addresses but it did not provide any phone numbers.

But I want to know what are good sites to compile a list, or what sites have the most depth of baseline information that I can filter out from there.So with that said, what mailing list source are people using to get quality leads?

Corrections are a B*thch - wait this is a family website, Corrects are painful.

Welcome to the site!

Welcome to BP @Cam Shasteen often the county website has information on tax sales.

Do you have a site in mind that goes through the neighborhood, talks about population demographics etc.
