I've been buying and selling MF in Vermont for 10 years. 

You evict them and sell the property to the next end buyer.  

I've been looking at some properties and before I get started, I wanted to know does anyone have any reputable General Contractor/Contractor along with property manager in Columbus, GA because I haven't had much of luck in that department yet?

In your instance, as the owner of the property you can have a direct non-licensed employee to perform property management.

The property had foundation work done just prior to the sale but continued having problems, even after I hired a second contractor to correct.

Quote from @Josh King: I have 2 rental properties I paid cash for years ago and I have never borrowed against them.

Create a tab for each property.

My latest vacation rental property is a charming 2-bedroom, 1-bathroom townhome located in Seattle's Queen Anne neighborhood.

Quote from @Patrick Roberts: Angel oak and A&D mortgage are two of the bigger lenders that I know of who will do 2nd's on investment properties as of a few months ago.

Then you can read a more in-depth book like The Book On Rental Property Investing by Brandon Turner or The Unofficial Guide to Real Estate Investing by Spencer Strauss.2.
