Finding comps for manufactured homes

[Jeremy Ferguson]

I have  come across a very motivated seller that keeps calling me back wanting me to come out and see her property and the manufactured home/ trailer she is selling. Her husband just passed and she is looking to move out quickly and head to FL closer to family. So I will be heading out tomorrow to take a look and hopefully make her a fair offer.

I have started looking for comps but can't find many similar units that have sold in the past 6 months. She is out in a rural area on about an acre of land, it's not a park. How would I determine a starting point or ball park. 

I am still new to REI and only have experience with single family homes at this point. Any help is appreciated.

My goal is to wholesale or if I can get her down low enough I will pay cash and either flip it or rent it out.
