Ex. you normally do STRs and you are looking to finance a mixed-use multifamily deal, and you don't mind paying the 2% in broker fees to lock down financing.

Any normal buyer with pre-approval will work with an agent, they would be stupid not to.

Just more common than you might imagine.. but it normal markets with normal sales conditions I agree with you..

Our north side buildings normally lease better through the MLS than through Zillow.

I add 15% to the normal rent for a Air BNB tenant as they are leasing the property with no risk or skin in the game, and they are making a profit off your lease.

how’s buyer going to get a loan for 70% when he’s putting none of his own money into the deal and just getting the seller to carryback in second position what would normally be the down payment?  

I would have a talk with the tenant(s) about the damages that are beyond the normal wears and tears.

YUP  EXACTLY  its calmed down a bunch but you know a few years ago on BP all you heard was cash flow cash flow cash flow  appreciation is gambling. 

Is there anyway to avoid the normal taxes involved?

There is no statutory rule enforcing this, but it's normally good advice.
