@Dremex,
To start with, I, just like you paid full price for my first unit, I now own another from resale. The full price unit was a purchased 10 years ago, we are VERY HAPPY our units.
As everyone has said, you must pay for your loan there is no other way. Your unit is candidly worthless in the resale market.
Now given what I've said, here is my advice:
a.) Get out of an Orlando or specifically a Florida based unit - You are paying the highest tax rate across the entire portfolio. ( that is a State/County thing, not a Hilton thing )
I pay less maintenance than you do on two units (13,120 points), both my units are Vegas Blvd.
b.) Pay off your debt with a Hilton AMEX - even if it is just monthly payments - you would be foolish not to ... 14x HH points.
To note, the first unit I owned was in Florida, Parc Soleil.
How do you get out of Florida? Try real hard with Corporate or in Vegas to get a good offer on an upgrade to a Platinum one week.
You will be offered your full payment price plus interest for your Gold unit as equity .... the key is getting the unit for a decent Hilton price.
( in truth, there is no good Hilton price and in truth this move may cost you more than just buying more points, but this is exactly what I did and I see that it has paid off in the long run )
I think the above will work honestly because you owe too much in truth and therefore, for the salesperson will look like they are making a sale when for you hopefully you only take a small step backwards.
i.e. today you owe 14k, when you are done you owe 16k but now in an upgraded unit.
I'd wait till year end to try to pull this off and see if they want to be aggressive.
Again this is exactly what I did to gain ownership of my 1 week Platinum in Vegas.
Lastly, my advice assumes you are keeping this unit, the above will not help you if you truly want out, and sadly if you truly want out, there is no way out.
