First flip just purchased

[Account Closed]

I am new to the site and new to investing.  It is someting I have always wanted to do, I finally got the courage to step out of the boat and sink or swim.  I am not handy (at all) so I did hire a contractor, who I think is pretty good...(I'm only about 1/2 way thru the reno.)  So for those of you who have used a contractor are there any signs or catch phrases I need to be on the look out for so I don't get taken?  Kind of an ambiguous question I know, but I could use any good advice.  I like the contractor, but he is also in charge of where my money goes...
