Elevator Maintenance costs

[Jason Cobb]

Hello, 

Is there a known method or rule to determine the average annual cost of elevator maintenance and inspections?   Age, model, make= $$/year  

Property has one elevator and I am currently researching this due to not having prior exposure or need to know.  Previous owner would provide past 24 months maintenance records, however, I am a longer term investor and need the real numbers over a ten year period.

Thank You for any insight, -J.
