Oh, gotta love it when you get called a newbie!
It still happens to those of us with experience, or at least it did for me recently. I spoke with an investor's assistant, and when I wasn't willing to just put out an offer on the first phone call, she acted as if I wasn't playing the game right and even called me "sweetie," and not in a nice way :) After investing for over 10 years and having over two dozen rental properties and been involved with bird dogging, wholesale deals, flips, small and large remodels, holds, etc., I'm not saying everything we do is perfect or refined, but we're not newbies. Bottom line here is that her words don't offend or affect me the way they might have when I was new to the game. Know that what you're doing isn't out of bounds, stick with your plan, and execute.
Ultimately, a deal is born when there is mutual need and mutual benefit. What we do is a service to the people we're willing to help, but to find those people, some sifting may be required :)
