Property Management commissions in the event of a sale

[Chenoah M.]

I've only seen a handful of property management agreements - curious on the general consensus as to whether a specific clause such as the one below is pretty much standard or not? Thanks for your input!

"Commissions in the event of a sale: If Tenant purchases property from Owner during the term of the contract or within six months after the termination of this contract, Owner agrees to pay Agent a commission equal to 5% of the sales price of the property."
