Merle Rosskam
CEO
The "10-year rule" at RV parks typically refers to policies where parks require RVs older than 10 years to meet specific condition, appearance, or model-year standards before being admitted or allowed to remain. From a tax and depreciation standpoint, this is unrelated but as a property owner, it affects occupancy and asset valuation, both of which factor into your cost segregation study and depreciation calculations.
