Google "Rid-A-Pest Little Rock AR" and you will see the local contact info.

I stumbled upon bigger pockets through a basic Google search.

Here's another Bigger Pockets blog post 10 Tried & True Strategies for Finding Cash Buyers.By the way, I used Google to find those articles. 

Since I'm purchasing from my grandmother and no agent or lawyer is involved, I have no starting point other than google.

Don't let the Google commute times trick you, anything inside the DC beltway is 3 hours in the morning, and evening when rush hour kicks in, at minimum.

You can do a google search for t=lenders of your specific type of property.

Some are basic some are very detailed.You can often filter by FMV, Taxes owed, if owner lives at property address or elsewhere, how many years they are behind etc.I filter my list and eliminate too cheap and too expensive FMV.Once I have the data pruned down I start looking at every thing on GIS and Google street view.I eliminate stuff I'm not interested in.

Please feel free to email or call anytime if you would like to chat further, all my info can easily be found on google.

I find things like this my Googling Xxxx example or template. 

You can also check their reviews online at Google, Facebook, or Yelp.
