MH can be a great start to real estate. As many will tell you, unlike SFH or MFH. Mobile homes typically do not appreciate.
First you want to meet the park manager or owner. Get a feel for them and let them know your intentions (rent, rent to own or contract for deed). Some of the ma and paw parks won’t let you in, from my experience. The parks I’ve worked with are owners who own numerous parks or big time real estate firms.
I just bought two of them recently and working on my third. The two I currently bought needed a little work. I'm currently renting them out on a year lease. The third I'm getting for free from a park. I plan on fixing it up and reselling it for cash or on payments. Find parks in your area that offer lower or average park rent and you can still make a solid ROI.
I got into it watching John Fedro videos. A lot of good information about flipping and financing homes. Along with how to work with parks, buyers and sellers. I would highly recommend him.
Many folks will try turn you away from mobile homes. There is a stigma associated with them. But can be great passive income if you buy them right.
Good luck!
