Matt,Thanks for the response and your angle.

Fastforward, the renovation process was quiet and I didn't ask for updates, rather I waited until it should have been close to completion to reach out (purchased Dec 18th or so) and then heard no response.  

Although I received a number of different responses, they are all incredibly valuable to me so I can see the thought process and look into things further! 

A Solo 401(k) is a qualified employer retirement plan, and needs a legitimate business activity with no full time employees to act as a sponsoring employer.You can read all day long on BP and get into paralysis of analysis, as well as digest some less than accurate information on the topic, to be sure.Alternately, you can read up a bit, with the goal of identifying a few professionals in the field, and then get on the phone. 

@Aaron Klatt Thanks for your response. 

I only use Rentometer for accurate rent estimates. 

Hope I understood your recommendation accurately?

Prior to our conversation I was leaning towards what I thought was close to accurate or even aggressive instead of planning for the worst and hoping for the best. 

I've got a question and I thank each and everyone of you for your response.
