Trouble selling a Flip?? need help

[Jared Elms]

I currently have a semi high end flip that is not selling and could use some advice. I get pretty good feedback but interest rates and economy have restricted the buyer pool. Was asking 649k, now currently at 569k. Completely renovated on a private golf course (on the fairway, first and second hole) I'm curious of my options as I have a lot of personal money tied up and a Hard Money lender I need to get rid of. Any suggestions would be appreciated.

Thanks in Advance...
