Is this short sale worth it?

[Sam Sand]

Morning BP,

I am looking at a shortsale, the bank will not take anything under 270k, i think the house needs at least 30k of work to bring it up to its full potential.

Right now the ARV is around 320k, but i believe my market area is on the tip and i am scared the second i pull the trigger the market will flop and ill be in the red.

I know there is a lot of "market crashing" talk, i usually think it is nonsense, but this house does seem over valued.

I know i am the only one that knows best for me, but what do you all think? 

thanks,
