Reserve assumptions

Monthly reserve target

A percentage assumption is only a starting point. Replace it with property-specific inspection findings, system ages and actual quotes.

Start with inspections, system ages and quotes

  • Inspection findings and specialist reports
  • Age and condition of roof, structure and major systems
  • Current repair or replacement quotes
  • A clearly labeled baseline reserve assumption

Combine recurring upkeep with known work

Choose a clear yearly starting point.

Add repairs found during the inspection.

Update the plan after each quote or major repair.

Replace the percentage as real evidence arrives

The monthly target spreads the entered annual baseline and near-term work over the chosen horizon.

Shorten the repair horizon and test the budget again

A general reserve must also fund known near-term work

Enter a transparent annual baseline, then add the roof, equipment or other work identified for the chosen funding horizon. Replace rough allowances with quotes as they arrive. Run a second case with a shorter deadline so the purchase decision reflects when cash may actually be needed.

Property risks no reserve formula can forecast

  • Actual failure timing
  • Inflation
  • Insurance-covered losses
