Go out there with the ability, capability, mindset, and intention that you are buying that house. 

They are major players in the social, political and economic policies and initiatives in their market.

They have great KPI and tracking capabilities that really allow you to be effective with your marketing spend and trim the fat as you go. 

You’re a player no matter what your situation is…you’re in the Real Estate game.

From my perspective, in a market where the institutional players are active (see https://www.biggerpockets.com/forums/311/topics/86191-the-modus-operandi-of-the-mass-buyer---a-case-study), I disagree with most of the above posts.

They have been in business since 1978 and are a big player in this field.

Things such as taxes and financing capabilities (among others) for instance. 

Three follow up questions: 1)Another thing that I was thinking would be a pro with a Realtor is that it would cost the tenant extra money to get in the place which I assume if they are willing to pay would be a better indication that they are looking to stay longer and are financially more capable. 2) The Realtor doesn't' cost me any thing correct? 

Well I personally do not wish to continue with his tenancy due to the circumstances of his wife passing and he is not capable of upkeeping this 4br/2ba home.

An experienced investor will be able to spot out a 'player' real estate agent/broker quickly.
