You can obtain bank financing usually if the mobile home park is:
75% occupied or greater
Debt Coverage ratio of 1.20
I have found it is easier to get local bank financing than from larger national institutions. If the park is in great shape, high occupancy (80%+) and high DCR I would try to pursue a long term loan “conduit financing”. I am currently getting a conduit loan on a MHP that I own and the terms are 6.1% at 10 years fixed, 30 year amortization, non-recourse. It is a little more hoops to qualify and get the loan however your cash flow goes through the roof and you have fixed financing for a long time.
