Pre-1976 Manufactured Home Financing for rental property in Arizona

Hi, I'm looking at a property that is technically a manufactured home built in 1963, but has been completely remodeled with updated electrical, plumbing, and a entire stick-built house built on to the original single-wide, which basically only retains the original walls. The deal is excellent in terms of DSCR, but I've been unable to find a lender who will lend on this property. Anyone have any recommendations for what lenders might be willing to work on this? This property is in Arizona. I could buy cash but not interesting in terms of return without financing.
