Marketing for Sellers, Skiptracing & DNC List

[Blake McCracken]

I received a list of tax delinquent properties from my county. The list included property owner, parcel ID, street address, amount each bill, and prior year. I assume prior year means a prior year that is on their tax bill? I filtered for properties that are 2016 and earlier in the "prior year" column to hit the >2 year deliquent mark. I filtered the list down to just individual owners and extracted their first and last names somewhat accurately using excel formulas. The original list of about 8,000 is now down to 337. 

Most skip tracing services that I've found require city & zip, which I do not have. Is there a way for me pull city and zip in batch format? Or will I need to do that for each individual property, after which I plan on uploading the entire list (now including the city & zip) to a skiptrace service and cold calling each property owner, cross referencing them to the do not call list, which I'm in the process of getting access to through the FTC's site. 

Thanks for taking the time to help. Any and all advice is appreciated. I am doing my best to "hustle" for my first deal. Any other 'low cost' marketing techniques are welcome. Ordering bandit signs today, planning on putting them out soon(after researching the best time to do that on here...). Trying my best to avoid spending several hundreds dollars on direct mail consistently, which per most advice is the only effective way to do it. Strongly considering door knocking preforeclosures with a informational 2-sided brochure in hand that I will create that points to their options, including first consulting HUD. I am taking a wholesale approach initially, like a lot of others I see on here doing, with the anticipation of doing bigger and badder things with an established marketing funnel. Meanwhile I'm getting the education required to be an agent and will evaluate after completing the education on whether or not I want to move forward with 'taking the test.' A lot of conflicting advice on here on whether that is an advantage or a hindrance to an investor.
