When to fire sale property

[Ramon Mota]

Last year my mom bought at restaurant in a small northern California town. After puting money into refreshing the eating area she opened. For a total of 39 days and then passed away. I just filled taxes and the business and it shows a -12k loss. So when people ask to see the books they see a loss and don't see any cash flow. She bought the building and business but the dirt is on a 15 year lease. 

So we have $3000 lease, $2400 insurance, $127 water, $160 power, $37 alarm and $850 LLC. Also sure I'm missing something. About $844 in the hole every month. No mortgage.

Anyway the place has been for sale for months but we can't take the loss much longer. We did a price drop 2 times so far. Should we show a big drop close to the bottom line we would take. Or should we leave room for a low ball offer to feel better. Any advise you may have would be helpful. 

Should we attempt to lease the building to someone else at the risk of loosing a possible sale?
