To compare the market rents against other similar properties, I could look at a map and find similar size apartment buildings in the area, and contact them to find the price range and configuration of their units to compare against... perhaps contact local property managers who might manage properties like this to see what they can share...

The columns on the right are the comparable sales.

Also, I’m able to find comparable jobs as a manager very easily.

Viewing and touching, and comparing various offers before placing offers is what I've been trying to do, while I prepare and save money to purchase my first duplex in the Spring!

There aren't a number of similar properties with which to compare value, which you need for conventional financing.If you buy this one, it is guaranteed that you will learn a lot about real estate investing.  

Selling is an option, but since I prefer buy hold over flip, I’d like to compare selling to equity tapping.

Otherwise, simply compare rates, points, term, etc, and make a decision.

Also since your investor is a member of the LLC they can be on the checking account and watch the money in real time this is a critical aspect of my companies.. and I don't have to make up reports etc.. they watch the business in real time … compared to if you have multiple investors and they are relying on your in house accounting and they are not on the checking account ( this mainly from the investors side of the table this is were things go sideways for investors.) no real access to the ACTUAL checking account only reports made up by the sponsor.. 

@Alex SmithThis question depends on so many elements. 

@Jay Hinrichs I believe anyone trying to sell their home can go on Zillow and receive and compare instant cash offers from investors, like invitation homes, etc.
