Looking for brokers’ opinions - Would you invoice? (seller rep)
Colleague and I have represented the landlord over the past 4 years banging out short leases mostly under 2k SF, with the dangled carrot being participation in the sale of the building. Been marketing for sale for 18-24 months. 

We sourced a qualified buyer and  successfully negotiated and executed a PSA. 

Buyer re-traded a few days prior to feasibility expiration based on findings in their DD. 

Seller (client) agreed to a 25% reduction of buyer’s total ask and held firm; willing to kill the deal due to the fact 1031 replacement properties in the appropriate price range are so limited in our current market/not of interest. 

We built good rapport with the buyer over the course of the deal and when we delivered the message that the deal was dead, he told us he thought we should still be compensated by our client for our work, and that we ran the process exceptionally from the seller’s side. 

We found out that there may also be a self-redevelopment play in the works for multi/residential and we’re office guys, so future sale opportunity/upside seems to be waning. 

I know we don’t get paid for “time invested”, but what would y’all do?
[{"id": "iboh2sk", "text": "Keep the relationship strong and move on.  Not worth getting some compensation out of something like that.  First, you legally probably don\u2019t have a right to any, and second, the industry is small and you don\u2019t want the reputation as the guy who will try and milk out fees if markets change or strategies change.", "replies": [{"id": "ibohsl7", "text": "Ya, you\u2019re right. \n\nSeems like my internal voice has been working overtime saying \u201ctake the high road\u201d a lot lately. \n\nIt\u2019ll pay off in the end, right? Right? Ha! \n\nHead down and on to the next. Cheers and good luck out there.", "replies": [{"id": "iboii1z", "text": "Hard to do for sure, but long term it\u2019s the right choice.  I\u2019ve had to cancel an appraisal assignment that was 90% done for legal reasons, and didn\u2019t charge the client even though I easily could have.  Moved on and now they\u2019re one of my best clients.
