I will be maintaining an internship with Daisy brand's (the sour cream company) sales division.

it does not sound like a deal that make sense, unless the seller are willing to short sale and still bank has the say on bottom line number.

Always do a math analysis and try to look at the prospective properties before you make an offer or at least have a clause in the sales contract that allows you the time (usually about 15 days) to make a detailed inspection and possibly back out of the deal without a penalty that will hurt you too much.I went to college too (and it is not mandatory) and I got a business degree that emphasized real estate.  

Thanks, I'm gonna read more on whole sales.

On the other hand, purchase prices at these sales can be very low.

The seller managed to purchase at a time where prices were still depressed and purchased through a short sale allowing a steep discount.

I haven't tried suggesting an installment sale or done an owner carry (other than one pre-foreclosure) and have just done cash wholesaling so far.

We are currently living in a college town [martin tn] and there are several duplex and quadplex that are for sale.

How are the commercial sales?

The best thing I've found is going on the county auditors page and searching the street your potential property is located on as well as a few nearby and identifying sales in the past 6 months.
