A seasonal park loan is a case study in why annual DSCR can mislead you on monthly payments
Take a 285k first position note against a 31 site RV park, sized at 62% of appraised value, 24 month term, monthly interest only. Structures like this are common and often perform fine, but seasonal parks expose a specific underwriting mistake worth studying closely. The structure works for a rental building and is wrong for this asset class. Monthly interest only assumes monthly cash flow, and a park doing something like 78% of its gross between mid May and mid September does not produce that. Picture a borrower who closes in April: payments 1 through 9 come easily because the season carries him. Payments 10 through 14 have to come from savings, and by payment 15, in March, a lender is fielding a late call nobody enjoys. Even when the borrower cures and the loan pays off in full, the cost shows up elsewhere: months of uncertainty, a site visit, legal fees to review default notices before anything gets sent, and the attention the situation demands. The underwriting error is usually a debt service coverage number run on annual NOI. Annual DSCR on a seasonal asset with monthly payments is close to meaningless. A month by month cash schedule would show a five month hole every winter, visible from the first spreadsheet. The better approach is to size the payment to the off season rather than the average, and take the difference in season. Some lenders use seasonal payment schedules, others fund an interest reserve at closing out of loan proceeds, roughly five months of payments held back. The reserve is generally the stronger structure, because it removes any question about whether the borrower is a saver. Whether either approach fits a given deal depends on the documents and the state, so that stays a conversation with an attorney. A competent borrower and good collateral do not save a payment schedule that does not match the way the money actually arrives.
