Mistakes of beginning wholesalers?

[Jeff NA]

Come heck or high water, I am forcing myself to finally jump into investing with both feet. I feel that I've read enough books, enough internet forums, gone to enough REIA meetings, and listened to enough podcasts to put it off any longer. I may well fall flat on my face, but it is what it is.

I have a few questions left. This one is primarily for end investors that have dealt with wholesalers in the past, but I welcome anyone with an opinion to chime in.

I've read that wholesalers can sometimes come off as amateurish and unprofessional, and while I accept that there will be a learning curve, I take my reputation seriously, and would prefer to say as few stupid things as possible as I get broken in. So I was wondering if anyone can tell me the common mistakes that wholesalers make, or how they can present themselves better?

I would imagine the biggest mistakes are not doing enough due diligence into repair costs and quality comps. I think I'm prepared for that. But I would appreciate any advice on how to come across as professional and reliable, and how to avoid sounding like someone you would never want to do business with.

Many thanks in advance.
