A rental apartment is still many people's idea of a safe investment. But at today's property prices and interest rates, the net yield often doesn't even beat a savings account. Let's do the maths.

How to calculate rental yield

Gross yield = annual rent ÷ purchase price × 100. From the gross yield you still need to subtract:

  • maintenance fund and insurance,
  • property tax and income tax on rent,
  • vacancy (budget for 1 month per year),
  • repairs and replacing furnishings.

A 4.5% gross yield therefore often leaves only 3–3.5% net — and that's before counting your own time spent managing the property.

When a buy-to-let makes sense

  1. You're buying well below market price (auction, renovation project).
  2. You're betting on long-term price growth in an attractive location.
  3. You want leverage — a mortgage lets you control a large asset with little capital.

Hassle-free alternatives

Real estate funds and REITs (real estate investment trusts traded on exchanges) give you property exposure from just a few dollars, with no tenants and no repairs. Returns are comparable and liquidity is incomparably better.

Real estate is a great portfolio addition — but it shouldn't be the only thing you own.
