Lease Renewal vs Turnover Analysis

Comparing the cost of retaining a tenant at increased rent versus finding a new tenant.

Renewal Gain

Annual Gain = (New Rent - Current Rent) x 12

Turnover Cost

Turnover Cost = Vacancy Months x Rent + Turnover Expenses

Decision Framework

  • If turnover cost exceeds annual gain, consider a smaller increase to retain the tenant
  • The longer it takes to recover turnover costs, the more valuable tenant retention becomes

    • 计算示例

    $1,600 rent with 5% increase proposed, expecting 1.5 months vacancy and $3,500 turnover costs if tenant leaves.

    1. New rent: $1,600 x 1.05 = $1,680
    2. Annual gain from increase: ($1,680 - $1,600) x 12 = $960
    3. Turnover vacancy cost: $1,600 x 1.5 = $2,400
    4. Total turnover cost: $2,400 + $3,500 = $5,900
    5. Months to recover: $5,900 / $80 = 73.8 months
    6. The $960 annual gain does not justify risking $5,900 in turnover costs
