This is one of those things it does not pay to try to handle yourself.

If you have ever been in a similar experience, I would love to hear how you handled it.

All leases have expired on the six houses by the way.Here's my question...how would you handle the transition process once I close on these houses?  

So your use with radiant heating would qualify as a situation that if I were to add AC I would first look at the Mini Splits.Another gotcha is make sure your electrical can handle the expected load. 

My goals are to get a flip going within 3 months and to start building a rental property portfolio with quality management companies handling the day to day operations of them.

I found the list on here with all the companies that handle the self directed IRAs and plan on calling and seeing what they can do for me, if anything.

Fannie Mae has very specific rules about how multiple offers are handled, and divulging other offers is expressly forbidden.

You would need someone to be at the front desk (collect rent, give keys, call the law if necessary, handle complaints, etc.), you would need cleaning people, and I think you would hire maintenance people as it happened, rather than keep someone on the clock when there is no work to be done.

I can handle making the deals and financing them, but would like a partner rather than a contractor working freelance to do the Rehabs.

I will assist with the tenant screening and I will handle any issues that arise regarding the property for a monthly fee.
