Expense Budgeting for Large MFH vs. Small MFH Properties

Hi. The rule of thumb for estimating CAPEX and Repairs/Maintenance is from 5-15% of monthly rent. Does this rule of thumb hold up for larger multifamily properties (above 4plex)? For example, would a 10-unit apartment complex still have CAPEX and Repair/Maintenance costs of 5-15%, or would it be a lower percentage due to scaling of costs over more units? Any advice is appreciated. Thanks!
