Tell your PM to raise the rents to market and fill both units asap with any applicants having a pulse and sell.I would seek out a good local real estate agent that knows the area and the value and get it listed and sold.

The operating company rules in connection with real estate must be satisfied so make sure to work with competent compliance professionals if you decide to pursue the use of 401k rollover funds to finance a start up.

However, I am seeking to diversify my real estate portfolio thru biggerpockets

We are of course a bit green, but we will be actively seeking out knowledge here on BiggerPockets and ramping up as quickly as possible.

If anyone used any of these professional before and experienced an exceptional service in a reasonable price please recommend me them.

They obviously dont have enough equity to get out and are seeking the agents to take a hit on their commissions (and want me to bring more cash)...

Seeking Partnership. 

I'd say a lot of it went over my head but its awesome to have this amazing community where you can seek out answers and get intelligent, relevant information from people who know what they're talking about and aren't pretentious about it.

If you went into the business transaction with a serious attitude and a professional process then yes they absolutely would. 

If you choose to go it alone, refer back to BP podcasts where people talk about how they manage their own properties and check the show notes for links to the software, resources etc. that they use to be professional, organized and ultimately successful.
