For a flip property, you're going to want to find a hard money lender or private money partner since traditional banks shy away from loans for such properties.

Stevie, to clarify my first paragraph above, you have two families of retirement accounts....traditional or Roth. 

if you purchase with an unsecured Line of Credit it will cause some challenges with a traditional refinance. 

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.
