I did not purchase my home from auction but through normal realtor channels.

It's always a good rule to maintain open communication with team members to avoid wrongful assumptions, plus it provides you feedback (what the realtor can do/not do to help) to see if the person is actually worthy of being on your team.The realtor should also be able to provide you with searches specifically for owner finance properties. 

Generally speaking, if an agent shows you more than one property, you should clearly communicate to the agent whether or not you are calling other agents.

Are you communicating that you should not "buy on a wrap and sell on a wrap" without getting the ok of the lender @Bill Gulley?

@Benjie DeVera and @Anthony Murphy, I think there is a communication gap. 

It could be that the permitting requirement they explained to me was only required of the MEP contractors but not communicated as such. 

Instead, prioritize your channels—blog, website, e-newsletter, emails, social media—and focus on those with the most potential.

How well do they communicate?

Lender's and Realtor's.However, if you use the lender's and they have a company they always use the communications may be helpful with getting things done.Also, if you are going to use him a lot it is brownie points to keep loan and title company that work well  on the research together.With Realtors's it's just brownie points you can use whom ever get's the job done to your satisfaction.Hope this helps!
