As for the 20% are scum and lie, you have a choice, if that is not you, then be yourself, act and dress professional, and let folks see you are there to provide a service, not just for the money.

Do I have to dress a certain way?

YOu will always have the mutli millionaire who looks dress's and acts like a pauper..

Oh, and dress casual, clean, nice, not looking like you're on the way to a Kendrick Lamar concert!  

Dress nicely when you visit them and be as professional as possible, that will score you lots of points.Good luck.

@Jordan DecuirAdvantages (for me)Volume of transactions and repeat businessUsually less emotional and more fact based decisions which fit my personalityA niche that many other agents aren't good atI get to help people build wealthI like numbers and analyzing dealsI was an investor before an agent so I understand themDisadvantages (for me)I walk through lots of junky houses and I like to dress nice usually lolMany offers to get a deal (being paperless helped this tremendously)I won't call it a disadvantage but the fix and flips and small multi families I work w investors on usually have a smaller sales price than the retail buyers.

I would just clean it and dress it up with shutters and paint the door.  

I did a write up of their strategy: How to buy a Korean apartment for $5,000It's Saturday.. no need to dress up, right??

We also have them sign an agreement with us about how to deal with owners and tenants (What to say , what not to say, how to dress, about being ontime, when they get paid on jobs etc..)We make sure they understand how we operate, what we expect of them but also what they can expect from us.

and adding a nice shower glass door will dress it up nicely.
