First time working with a wholesaler. I asked for one more walk-through. unhappy

I just started buying off-market properties for BRRR for myself. I usually JV with my partner do flips, but he handles everything. I only contributed financially and gave some design ideas. That says I don't have much experience.

PinPoint Offers sent me a few deals, and I placed an offer on one without seeing it. They called me, saying my offers were the top ones, and gave me a very short notice to look at the property. Yesterday, at 4:30 p.m., I got the notice, and I had to be there at 6 p.m. I went there by myself and had a budget in mind afterward. I actually increased my original offer by 10k, and PinPoint accepted my offer today. My flipper friend suggested I go there tomorrow with his contractor to ensure I am in good hands. I talked to PInPoint about this. PInPoint was very unhappy and seemed like I made this very difficult. 

My question is: am I acting dramatically? Out of norm? Break some industrial rules?

non-refundable EMD is due in 24 hours, which is tomorrow 6pm. We can go there and have a look anytime before then, and I can send EMD if everything is as I planned. It won't delay any progress. The owner lives in the house, but she is very friendly. I don't think it will be an issue to go there one more time for 10 minutes. PinPoint sounded like if you want to have a look again, we will give the offer to others. Anyway, the PinPoint guy said I will have to talk to my team tomorrow.

I have never bought directly from the wholesaler or PinPoint. Am I breaking any rules here?
