Or should I just walk away and concentrate on renting the one property we have under contract?

That way you can buy a duplex, tri-plex, or a 4-plex and get the tenants to pay you your mortgage payment usually.I would concentrate on what is average for that neighberhood.  

And talk about predatory, points on my sale price, not good.As to originations, there are many RMLOs out there who think they are compliant in doing seller financing, actually not from several fronts, their employer/broker must have such loans in their charter, insured and bonded lenders aren't covered with equity funded notes, and if they do any volume they may have loan concentration issues of high cost mortgages, this goes much deeper than what our newish loan originator testing goes to that they learn and it doesn't even go into underwriting!  

I am new to Real Estate investing from the Cincinnati and Dayton Ohio market and am interested in concentrating on one area first. 

Hi all, i'm a real estate investor from Connecticut and Massachusetts previously concentrating on buy and hold strategies.

I'm trying to identify a good area with reasonable multi-family inventory - are you finding a higher concentration of multifamily in a given area?  

And after that I'm going to be concentrating on acquiring a larger multi family building (maybe 5 to 30 units).

I agree with the poster above ... business with a concentration in Finance would be my first pick ... it applies well to RE, and it also "travels well" if you decide to initially pursue a job outside of RE ...

And finally, there is diversification of the stock portfolio so that all the dividend income is not concentrated on one (or just a few) companies or industries. 

Instead of concentrating on purchasing a buy and hold property, maybe you should think about getting your license and generating extra income through being a realtor.
