We have a ton of radon here in PA so I submit in my reply if radon comes back high “Seller at sellers expense to install radon remediation system by ABC Radon Specialists and furnish receipts of completed work and satisfactory retesting of the radon level...” this way I know it’s my guy doing it and will be done right.

I would highly suggest to listen to ALL the BP podcasts and read Millionaire Real Estate Investor, ABC’s of Real Estate Investing, and Rich Dad Poor Dad if you haven’t so already.

I would argue that I’m not speculating at all.

Numbers don't lie...don't argue with them or you will lose.

Hard to argue with J Beard answer.

One of these connections is a cousin at let's say ABC investments. 

Generally there is additional language that if another brokerage re-listed the property and a buyer or contact purchases that was not a contact from when it was initially listed then the first brokerage is not due a commission.Sometimes in these cases the brokerages will argue back and forth over who was procuring cause to affect a sale.

I can't tell you how many times people on these forums just dig in and want to argue.

If so, I'd argue I would need a finders fee for getting the deal, a % for accounting etc.

Yes is a no brainer, no is much more difficult to argue.
