Make some low ball offers, 30 a day to start looking for deals.

I'm not a certified mentor, but I trust you'd be in good hands with any of the mentors there.If you just want to check out the site or get the ball rolling with the onboarding process, check out the company website HERE. 

Send everything over to your closing company that was listed on the contract and let them start pulling title and get the ball rolling. 

As someone else mentioned you are only kicking the ball down the road with a trim and will need to cut it at some point.  450 isn’t a big enough difference and you will need to trim it again in a few years anyway.  

Short term and long term I have no rate crystal ball, but medium term (say 12-36 months, inside the window of where it would matter for a 7/6 or 10/6 ARM) adjustable rates will be adjusting downwards (& my crystal ball is just repeating what economists are saying about inflation, the only addition being that "rates follow inflation"). - Long term, no interest rate crystal balls, and also no point to plan more than a few years out IMO, "the first casualty of war is the plan." 

Rehabs could throw curve balls.

A crystal ball would be helpful in making the latter choice.

Owners were low balled by another wholesaler so we offered them more and it made them happy.

Get the ball rolling so it can just continue to grow. 

Doing is a different ball game than saying!
