Open the Mortgage Calculator →One of the most debated personal finance questions is whether renting or buying a home is the better financial decision. The honest answer is: it depends on your numbers, your timeline, and your local market. Here is a clear framework for making the right call.
Financial planner Ben Felix popularised the 5% rule as a quick way to compare renting vs buying. Take the home price and multiply by 5%. If your annual rent is less than that amount, renting is likely the better financial choice.
Example: $500,000 home × 5% = $25,000/year, or $2,083/month. If you can rent a comparable property for less than $2,083/month, renting may be financially superior.
The 5% breaks down as: ~1% property tax, ~1% maintenance and insurance, and ~3% opportunity cost (the return you forgo by having capital tied up in property equity rather than invested).
Buying has high upfront costs: closing costs, stamp duty, transfer fees, and moving expenses. These typically add 3–5% of the purchase price. This means you need to stay in the property long enough for appreciation and equity build-up to outpace those costs.
| Market | Typical Break-Even Period |
|---|---|
| Low-cost city (e.g. Houston, TX) | 2–3 years |
| Medium-cost city (e.g. Chicago, IL) | 4–5 years |
| High-cost city (e.g. San Francisco, London) | 7–12+ years |
| South Africa (major cities) | 4–6 years |
If you plan to move within 3–4 years, renting is almost always the right financial decision in most markets.
USA: Mortgage interest is tax-deductible up to $750,000 of loan value (if you itemise). Property taxes vary enormously by state — New Jersey averages 2.2%, while Hawaii averages 0.3%.
UK: Stamp Duty Land Tax adds 2–12% in upfront costs. First-time buyer relief is available. The UK buy-to-let market has changed significantly since 2017 tax reforms.
South Africa: Transfer duty is exempt on properties under R1,100,000. Bond registration costs add ~1.5–2% to purchase costs. Interest rates at prime (~11.75% in 2024) make affordability challenging relative to historical norms.

Run your numbers with the 5% rule, be honest about your likely timeline, and consider whether the non-financial benefits of ownership (stability, customisation) are worth the premium in your specific market. For most people in high-cost cities planning to stay 5+ years, buying makes financial sense. For those with short horizons or in frothy markets, renting and investing the difference is often the better path.
