Quick Answer

Rental Property Cash Flow Before Making an Offer is worth reviewing before you trust a calculator result because the assumptions behind the model usually matter as much as the formula.

Key Takeaways

  • Purchase price and down payment
  • Mortgage rate, term, taxes, and insurance
  • Rent supported by local comps
  • Vacancy, repairs, management, and reserves
  • Cash flow after financing and operating costs

Underwrite the monthly reality first

Purchase price matters, but monthly cash flow is where many rental deals fail. Model payment, taxes, insurance, repairs, vacancy, management, and reserves before deciding whether the rent supports the offer.

Use conservative rent and expense assumptions

A deal that only works with top-market rent and low expenses is fragile. Compare a base case with a slower leasing period, higher repairs, and realistic vacancy.

Checklist Before You Decide

  • Purchase price and down payment
  • Mortgage rate, term, taxes, and insurance
  • Rent supported by local comps
  • Vacancy, repairs, management, and reserves
  • Cash flow after financing and operating costs

FAQ

What is the first number to check on a rental deal?

Start with monthly cash flow after payment and normal operating expenses. Appreciation and tax benefits matter, but they should not hide a weak monthly operating model.
