Appreciate the response @Larry.
In this case I'm pretty comfortable with the comps, $240,000 is actually the low for the area/size with an average in the $270,000 over the last 6 months. I've just started talking to my realtor from my primary residence purchase (my only RE experience to draw on) to verify my comps are reasonable. The deal becomes far more palatable with a larger spread.
I'm not overly concerned with making a killing on this first deal (although obviously it wouldn't hurt), I really am looking at it as an opportunity to get some hands-on experience, and to enhance my ability in assessing repair costs and my knowledge of the local market. My day job is analytically oriented, so by nature I won't make a deal unless I'm sound in the numbers; at the same time I've seen it mentioned here numerous times that the biggest recommendation is to start making actions.
Hope your week is going well as we approach Thanksgiving, and as always thanks for the advice!
