Despite being very handy, I work a FT job, I have a family and other commitments, thus my time is extremely limited and I've found that for me, it's more lucrative (mostly in the long run) to do flip-to-rents (using the BRRRR method) on the side (and keeping my full time W2 job). 

But keep in mind that your ballpark isn't accurate either - and even when you have a full bid from committed contractors, you're going to be a little bit off on your final expenses. 

I have always been interested in real estate, so I don't think commitment is the problem.

Would I be able to secure a loan that high if I can get 2-3 people to commit?

This is a group of professionals that voluntarily commit to a higher standard.

With my clients I work with them one on one and require a commitment.

I went to one mastermind.. and while I was temped to join.. by the time I looked at the time commitment and what at my stage of career was looking to do.. decided it was not for me. 

National chains also take a VERY LONG time to commit to a center or a site versus a mom and pop to regional tenant.

I've been reading posts for a couple months now as well as listening to different podcasts, and I wanted to join in now that I have started my market methods and committed to the endeavor!

I would just make sure the funds are committed before you bid.
