Yes, cash can be powerful, but when it's in large supply, it won't help to differentiate your offer.

And when looking at commercial brokers you'll maybe want to spend some time differentiating between those who specialize in sales and leasing. 

However, since FHA differentiates between co-borrowers and cosigners, would this affect things if she were a cosigner, NOT a co-borrower?

Every area is different. I

That's the only way you'll differentiate yourself in a tight market with other listings that already have reviews.

You know what you want now for yourself in 5 years, but things change so in 5 years that may be quite different. I

So if someone has their listing on vrbo as well so long as they have the calendars sync'd it would pick up that vrbo booking since it would block the dates off of the person's AirBNB calendar.I think the biggest problem is that they have no way of differentiating a booking vs. an owner stay. 

The only different is I do NOT delete these contacts so that for my next property listing in the area, if the person call again, I sort of have some existing data to work with.- If the person does not call or text back one hour before the showing, I sometimes text to get confirmation at around 30 min before the showing.

You need something that differentiates your units compared to the others, so that you don't have to go down as far as all of the other vanilla rentals.As for appreciation, don't let your brother "be that guy" who buys in an area "just because it is booming" and hoping that prices will keep rising. 

Hi,I am interviewing with a couple of brokerages tomorrow and am trying to compile a list of questions to ask to see which brokerage is the right fit for me.Is there anything I should definitely ask to differentiate between brokerages?
