How do you suppose I convince or influence him/her to do so ?

I'd rather learn about what influences buying behavior than what makes Pavlov's dogs salivate. 

Learn how to talk to and influence appraisers

Have your main influencer (spouse if applicable) read "Rich dad pot dad" let them know it's just so they can understand where you are coming from.

To put it plainly, I value his influence in the local circles and his connections throughout town.  

Bulk owner board members, by virtue of their voting power, often carry great influence in decisions made by the board.

Posting on BP and sharing real estate information with your sphere of influence (and social media) is a great way to get started.

However, the most significant influence tends to be the yearly seasons of winter, spring, summer, and fall.The social, economic, and political calendar of the United States operates based on the yearly seasons.

Maybe I’m letting my ego influence my thinking.  

There are resources you can find that lay out different methods for building up your sphere of influence, but I personally like catching up via phone, meeting up for coffee, or doing something fun as a touch point.
