1st Wholesale Deal in the Making?????

I know an older couple in a 55+ gated community. They are under water on their home and are currently make payments of $1900/mo to keep the mortgage on their home. They informed me that they will be doing a short sale in the near future.

The home is worth $270k and they owe just about the same.

Any advice on how can I capitalize as a new wholesaler? Or should I wait to make an offer during the short sale period?
