I actually had an initial phone call with the co-host that ended up lasting an hour because he kept giving me tips and local knowledge.

And don't get me started on the former point, there's plentiful of experiences first hand where agents just try to get too cute due to a lack of knowledge and a dogmatic view of a 6month lookback at pricing.

I want to say that this is pure wisdom and years and years of knowledge and experience! 

If there is one, and they did not take their interest with actual knowledge of the easement, then the new deed would need to be agreed to by that third party or would be subordinate to that prior interest.
