First Short Sale.. Looking For Advice.

The Subject Property is a Single Family home in Cincinnati OH. I have ordered payoff on both properties. but this is the info I have gathered from Banks. 1st Mortgage - $93K 2nd Mortgage - $26K $5k in back taxes 2k yearly taxes Needs about 20k worth of work to fix up. Comps support a FMV of $100k - $130k I have my real estate license but I live out of town so I am working with a local Real estate agent to get this done. I have 2 questions. 1. Should the agent represent me as a buyer or should he list the property and represent the seller. Either way the Bank pays the discounted commissions. 2. Assuming the FMV is $115k What should be my starting point in terms of negotiating the best price with both mortgages. Thanks in advance
