🧠 Key Metrics Explained

Understand the numbers that drive smart rental investments

💵

Cash Flow

Monthly rent minus all expenses and mortgage. Positive cash flow means the property pays you each month.

📊

Cap Rate

Net operating income divided by purchase price. A quick way to compare properties, regardless of financing.

📈

Cash‑on‑Cash Return

Annual cash flow divided by total cash invested. Shows how hard your money is working for you.

🔄

BRRRR Method

Buy, Rehab, Rent, Refinance, Repeat. Pull out equity after renovation to fund the next deal — often with little of your own cash left in.

⚖️

Break‑Even Rent

The minimum monthly rent needed to cover all costs. Below this, you’re losing money every month.

🏆

Total ROI

Combines cash flow, appreciation, and loan paydown over your holding period — the full picture of your return.

💡 Pro Tips for Rental Property Investors

Make every investment count with these proven strategies:

  • Use the 1% Rule as a quick filter: Monthly rent should ideally be at least 1% of the purchase price. Not always possible, but a great starting point.
  • Always run conservative numbers: Overestimate vacancy and maintenance. If the deal still looks good, you have a margin of safety.
  • Know your market’s cap rates: A 6% cap rate might be great in one city and terrible in another. Compare locally.
  • Plan for capital expenditures: Roofs, HVAC systems, and appliances will eventually need replacement — set aside reserves even if the calculator doesn’t show a separate line item.
  • Factor in property management: Even if you self‑manage initially, modeling a management fee ensures the property can eventually run without you.
  • Look for value‑add opportunities: Properties where you can increase rent through renovations often generate the highest returns — especially with BRRRR.
  • Hold for the long term: Transaction costs are high in real estate. The longer you hold, the more you benefit from appreciation and loan paydown.

❓ Rental Investing FAQs

Common questions about analyzing rental property returns:

What is a good cash‑on‑cash return for a rental?
Many experienced investors aim for 8–12% cash‑on‑cash return. However, in hot markets returns may be lower, and you might still benefit from appreciation. Always compare to other investments available to you.
How accurate is the BRRRR mode in this calculator?
It models a classic BRRRR: you purchase and rehab, then refinance at the after‑repair value (ARV) with a new loan at a specified LTV. Any cash pulled out reduces your net invested capital. The calculator updates cash flow and cash‑on‑cash return accordingly. Actual refinance terms depend on lender requirements and market conditions.
What's the difference between cap rate and cash‑on‑cash return?
Cap rate ignores financing — it’s based on the property’s net operating income divided by the purchase price. Cash‑on‑cash return measures the actual cash flow you receive relative to the cash you invested. A high cap rate doesn’t automatically mean high cash‑on‑cash return if you use a lot of debt.
Should I include maintenance and vacancy even for a new property?
Absolutely. Even a brand‑new property will have some maintenance, and vacancy can happen between tenants. Using 5–10% of rent for each is a common conservative practice.
What if my monthly cash flow is negative?
Negative cash flow means you’re feeding the property each month. This might still be acceptable if you expect strong appreciation, but it increases your risk. This calculator shows break‑even rent to help you understand what rent you actually need.
Does this calculator account for taxes?
The calculator includes property tax as an expense, but it does not model income taxes on rental profit or capital gains. Real estate offers tax advantages such as depreciation, which can reduce taxable income. Consult a tax professional for personalized advice.
