As most things, key is buying right and ensuring that you have the right relationships to do so. 

I'll be sure to set up the key word alerts.

I think you are referring to "cash for keys," be it through a formal rent control method,  or through ad hoc agreements with the tenants (cash and free rent for "x" period of time, etc..).

I hope to find turn key properties but if I can get fixer and upper one for a good deal, I'll get it.

The key is consistency.

They Key is to first have a good team on the ground you can trust, and know that they are capable and have experience in Rehabbing properties to good standard. 

The seller's (Owner's) relative who managed this property is not surrendering the keys to the seller.

NOT all of them are bad (there are some great ones out there), but I can see how a turnkey operation where people buy blindly, could be an opportunity for bad operators to take advantage. just read the Morris invest threads to understand your concern on quote un quote turn key.

The key is to find out what matters to your seller and try to work with that in ways that are still advantageous to you.

You may also want to consider "Cash for Keys" to avoid having to do an eviction - letting that tenant know how an eviction will negatively effect them going forward.I also started with Cozy.co for tenant screening and rent collection.
