Yup. From what I know , commercial loans in the mobile home park space can be really creative.
So you mentioned that institutions see this as too small and hard money is too expensive and restrictive.
One way I’ve read of is to try for a seller finance. Is that something the seller is willing to do? It’s the cash flow that they received before but for none of the work now. The terms are all completely negotiable in this case.
A bank with the ability to do portfolio loans can also be an option here. These are usually smaller local banks that probably won’t have a requirement of a mil and up for a loan. Worth it to call around all the banks .
Or if you have family and friends you can raise money from in the form of private money, that is another option. Everyone’s family and friend situation is different though and I’d say be prepared to show proof of why this is a good opportunity for them to mke a return in their money. That’s inportant, you are doing them he favor and not just asking for money.
Again I’m not an experienced financier but these are the most common ways I hear of to finance mobile home parks. I hope this helps even a little.
Best of luck .
