Inflation and Appreciation Variable for Long Term Projections

[Joseph M.]

What variables would you use for the long-term projections of your portfolio? I am trying to create a conservative, middle of the road and aggressive calculation of my net worth and net profit.

This article says inflation averages 3% a year long-term and real estate 3.1%.  This website says inflation averages 3.22%. There is a lot of data out there.

What numbers would you use for the projections below? And what data would you use to get those numbers?

Property Value Increase: Conservative -      Middle of the Road -      Aggressive -

Rent Increase: Conservative -        Middle of the Road -         Aggressive -

Tax Increase: Conservative -       Middle of the Road -       Aggressive -

Insurance Increase: Conservative -       Middle of the Road -       Aggressive -

Association Fee Increase: Conservative -       Middle of the Road -       Aggressive -

Maintenance Cost Increase: Conservative -         Middle of the Road -        Aggressive -
