(Guess we'll be here on BP constantly asking for help).Stick to your guns and keep folks honest.Congratulations again and I hope your contractor is experienced and makes the rehab smoother than the acquisition.

Should I quitclaim him onto title now as Joint Tenants?

The constant complaining is so annoying to hear. 

So network like crazy and constantly.

My wife and I are in the process of closing on our first duplex that we will be house hacking, while this closes I find myself constantly thinking about how to get our next deal.

If they like it ask for referrals to people they know that will invest with you (JV, note, joint title).

And if their nose is still out of joint, move on. 

You might research which builders are doing those new homes in that neighborhood and see if any would be interested in doing a joint venture with you.

They may get tired of this if you bother them constantly with requesting comps without offering to pay them a small fee.  

Once you've done that, you can locate Joint venture partners that have experience in either and negotiate some sort of agreement where they present the deal, manage the work, and report back to you.
