We visited place, checked out a few properties, came back, made an offer, negotiated and finally property is under contract! 

I agree with what @John Underwood said about checking your market.

Many sellers are tired of being landlords but wouldn't mind collecting a check every month still. 

Check out Shelby and Gastonia which are nearby. 

But when they resell them they don't really know or check if liens exist.So in summary, any deed is fine depnsing on the buyer doing CORRECT reseach.

Look for rental comps in the area and check the math.

You need to check with the local jurisdiction (your property manager should know),In this particular case, due to the length if you have a receipt you can show that to them and that should be good in most courts if this goes to majors.

I had to call my Indiana property manager because of recent storm to check on hail damage.

I am looking to create a system which will allow me to analyze and choose markets more efficiently.I want to have a pool of resources/websites that I follow step by step so for example, 1: Check the housing prices, 2: Check the population, 3: Unemployment rate, etc... and then I will pull this data from the websites that provide it and keep going down the checklist.

Once that is completed, then run the credit for those that meet the first round of criteria.You can double check but I have not heard you have to prioritize a Section 8 tenant, you just can't reject them because of source of income.
