Wholesale question on property?

[Brad Swaney]

Put offer in on property and offer was accepted.  This is a condo I was planning on using as investment property.   Talking to other investors in the condo community.   Someone is offering me $6,000 more then what my offer was accepted at.   I signed and everything was accepted from current owner through realtor.   Still waiting on bank to process everything.   If I sold for the $6,000 more.  What kind of penalties, taxes or so on would I be responsible for?
