Pretty Houses...First time SS..

I have got the inital paperwork with a customer on a short sale.
The house is upside down with Wells Fargo. I have already got the process semi-start with WF.Here are the numbers

Customer owe- 147
FMV- around 120k
Repair…Maybe 2k (general painting no major work)

What can I do to get the BPO down without destroying the house now? The house is in great condition. It doesnt really need any major work. With a pretty house its harder to get a lower BPO to create equity.

Second question. If I already have an investor who is willing to buy after WF agree to an offer, Do I still have to find a realtor to list it with? That also will cut into the equity as I am not a realtor?

Responses GREATLY appreciated!!!
