While having an established business as a tenant is generally a good thing, my concern is the fact that it has been around for 20+ years. 

Starting with the Ultimate Beginners Guide to Real Estate Investing.Can't wait to meetup and learn from all the experience investors on the forum as well as the newbies like me, and having great discussions about the Real Estate investing world.

My main concern is paying back my investors ASAP.

I just closed and was given a check in the amount of both tenants deposits.Right away you want to call and transfer any utilities that the previous owner was paying, as well as call and set up a time to introduce yourself to them, as well as lay out clear guidelines and expectations as to what to expect with you as the new owner, ie. where and when to send payment, contact info and info on what to do if there are any issues that need to be addressed.I just closed on a new duplex and acquired tenants, i called right away and started service for water and garbage for the tenants, as well as met with them in person, I showed up with a copy of their current lease agreement for them to have as a refresher, a basic rental application for them to fill out to make sure i had the most current information about employment, tenants, contact info, as well as had them make a list of concerns and things that need repair. 

My concern is that I don't want an issue with the buyer trying to make a deal with the seller directly; since they have address, pricing etc.,.

I might try and bluff with "after I reviewed the video" but otherwise you just have to decide about not renewing her lease or evicting.The concern with the eviction....on what grounds?

Chief among my concerns would probably be my ability to resell the thing, once improved and rented out.Thoughts?
