I would suggest speaking to a lender about that. There are different requirements, but it is definately possible and it happens all the time. It used to be very difficult, but the rules have changed - yet again. I have several lenders I work with that I'm sure would be willing to talk with you. I also am familiar with the mfg home parks in Cameron Park and the surrounding areas. In fact, I am listing another one this week.
Please call me or email me so I can help. 530-409-4671 or email@example.com. You can also search with no obligation for free on my website at http://www.RealEstateCentral.org.
I hope that helped!
