I would like to start evaluating/interviewing contractors to start on this work.Do you have any recommendations for contractors that could do what I'm mentioning above?

Slow but steady progress.

I personally think it is easier and cleaner to pay as the project progresses.

I'm wanting to understand the criteria that a property appraiser will use to evaluate the kitchen?

Nothing would be a deal breaker alone, but factor this level of expertise in when evaluating the complete picture.For example, a big problem that I've seen is if a single tenant building is applying with a regular lender, sometimes they apply a vacancy to their own DSCR (Debt Service Coverage Ratio), and they apply a vacancy factor for a single tenant building, which is just wildly inappropriate.

Evaluate markets to determine profitable real estate investments.

Reno is still in progress...

You should begin to establish a process for evaluating your rental market, your advertising, process for interviewing tenants including a formal series of questions.

They are the gatekeeper for all plan transactions, with the resulting paperwork, delays, and cost that go along with that.You may wish to evaluate the Checkbook IRA LLC or Solo 401k (if you qualify).  

Like @Jesse T. mentioned there are so many majors that can help.Good luck with whatever you choose, and please keep us posted on your progress!
