I've started looking at Columbus because my business partners have found success doing Mid Term Rentals there and the returns are solid.

Partner up with someone.

Also, you won't be scrambling at closing time to identify and hire your most important ongoing partner.As far as the other partners, I agree with @Michael Smythe's list above.

I then met my current partner, and we started investing together.Honestly, having a partner has been a huge help for me.

I know that I stand to make more money per renovation by just paying for the work, but I'm attracted to the idea of partnering with him for a few reasons.

You may also want to really consider trying to find an experienced partner after you have done a deal or two - this may be key to helping you reach your five year goal. 

Meet people, network, and then ask to partner with someone.

Never, ever heard of a lending firm recruiting capital partners like that, so I'd be careful. 

Another option would be to tell them you have to make decisions based on your investors best interests.Your investing partner could be your significant other, but they don't have to know that.That way if difficult decisions have to be made in the future the frustration would be at "the investor" and not directly at you.

Investing in sectors you know nothing about - even if you think your “partner” has expertise2.
