How to calculate fair value for a multi-use trailer park?

[Jeffrey Duby]

As the description says, I have access to and offmarket deal I stumbled across in west virginia, it's a older couple that is looking to sell a unique property in the mountains of eastern WV. It abuts george washington national forest and is very appealing. The asking price is 890,000 USD. The issue is that I'm having a really hard time figuring out how to assign a value to it. Would this be based simply on an income analysis? What are expenses likely to be? Have any investors out there done anything like this? I will be getting the financials tonight, what are good questions to ask. If anyone is interested, I'm happy to assign an option should the situation arise. Thanks in advance everyone?
