<human>: Can you give me the gist of the text in a nutshell?

Hi /r/personalfinance,

I graduated this past May and found a job. Unfortunately my parents are divorcing and they are dividing up furniture and the like. Among things listed as "furniture" is my high-end piano that my parents got for me in high school. Since my parents are splitting, it is my responsibility to sell it or find someplace to put it.

The original price of the piano was about 29-32k but the salesman was going out of business so he sold it to us for 19k. Years later, that piano would get me scholarships to college and several cool gigs in school. 

I don't know if the storage facility (my dad offered to pay for a facility for a few months) has humidity control. Without that, the inner cloth of the piano would get damaged and cost me a lot to repair/replace. Needless to say, I'm not in a position to afford the storage by myself.

To make matters more difficult, my parents are supposed to leave the house they were renting (where the piano is) by the end of the month. They only recently told me that they were leaving the house and I've only recently been able to post it online to try and sell it. At this point it seems highly unrealistic that I could sell the piano by the end of the month, let alone for what it is worth.

I need a better plan of attack with this. The piano has to go but I'd like to get what I was told it was worth by the piano salesman (different guy than the one a few years back) with whom I consulted a few weeks ago (he told me take no less than $15,000 for it). 

Is it better to just to sell it for cheap just to be rid of it? Would it be advantageous for me to be patient and keep it in storage for a few months? Maybe there's something I'm missing?

Any help at this point would be greatly appreciated.
