Non traditional lending may see this as an opportunity to cash in.  

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...

Or,  I'm interested in other strategies to try to leverage the property for investment without a traditional sale that would affect their benefits.Thank you,Scott S. 

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.  

If so, can I then use a traditional mortgage for the remainder of the purchase?

But the traditional commission model doesn’t work because no one with the requisite skill to find said deal is going to go through the BS of a HUD foreclosure (for example) for a $600 commission.

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