I am starting my first rehab project with my sister! Any advice?

[Tony H Truong]

Hello BiggerPockets,

I am starting my first rehab project very soon. I have an inspector coming out to the property at 10am and then I have 3 contractors coming out 30 mins after that. Is that consider rude? 

I am been so focus on how to get the deal, and now that I have a deal I am not sure how to start my rehab. Should I let my contractor plan the steps to take or should I let me him know how I want it to go? I was thinking tackling the big things first like plumbing, electrical and Hvac. Then move on to Windows and door. Then bathrooms. Then interior painting and last the floors. And exterior last.

Do you have any tips on how I can communicate with my contractors so I don't get screwed over? 

Anything will help! Thank you for taking your time and reading this!
