The short answer

Here's the spreadsheet I use for every investment property I evaluate. Most investors miss at least three of these line items.

The longer answer

Monthly Income:

  • Gross rental income: $
  • Less: Vacancy allowance (5%): $
  • Less: Rent concessions/loss to lease: $
  • Effective Gross Income: $

Monthly Expenses:

  • Mortgage (P&I): $
  • Property taxes: $
  • Insurance: $
  • Maintenance reserve (5% of gross rent): $
  • Property management (8-10%, if used): $
  • HOA fees (if applicable): $
  • Capital expenditure reserve (5%): $
  • Utilities (if landlord-paid): $
  • Total Expenses: $

The Three Profitability Metrics

  1. Cash Flow = Effective Gross Income - Total Expenses. This needs to be positive. Even $100/month means the property pays for itself.
  1. Cap Rate = Net Operating Income / Purchase Price. Target 5%+ in Minneapolis. 7%+ in St. Paul or North Minneapolis.
  1. Cash-on-Cash Return = Annual Cash Flow / Total Cash Invested. This accounts for your down payment, closing costs, and initial repairs. Target 8%+.

The four things most investors forget:

  1. Capital expenditure reserve (roof, HVAC, appliances — they WILL need replacing)
  2. Vacancy (tenants leave, and finding new ones takes time)
  3. Property tax increases (Minnesota reassesses regularly)
  4. Insurance cost increases (15-20% in the last two years alone)

My rule: If a property doesn't cash flow positive with ALL reserves funded, it's not an investment — it's a speculation. Pass.
