Why would you hold firm on your asking price, hoping things might get better? That makes your property a stale listing that no one will consider. A vacant house is a magnet for thieves and vandals. An unnoticed water leak could destroy the structure. A freeze that gets the water lines will do the same. Your insurance company might cancel you, especially since this is rural property.
Tenants in this type of property tend to be of lower quality, although that varies with location. More risk to your property. In your shoes, if I could afford to do so, I might sell this, eat the loss, and think twice about purchasing a similar property in the future.
