We analyse the key factors that determine when buying is better than renting: price/rent ratio, time horizon, mortgage rate and opportunity cost.

The price/rent ratio

The most widely used indicator for comparing property markets is the PER (Price-to-Earnings Ratio): purchase price divided by annual rent. A PER of 20 means it would take 20 years of rent to 'pay for' the flat. Cities like Madrid or Barcelona have PERs above 30; in medium-sized cities it can fall to 15–18.

Opportunity cost: what few calculators include

The mortgage deposit (typically 20% of the price plus costs) is money you could invest instead of tying up. If €50,000 invested in an index fund grows at 7% per year for 25 years, it becomes over €270,000. That lost growth is the opportunity cost of buying.

Purchase costs you must not forget

  • Transfer tax or VAT: 6–10% of price (by region and whether new or second-hand)
  • Notary and registration: ~1% of price
  • Valuation: €300–600
  • Mortgage opening fee: 0–1%
  • Conveyancing: €300–1,000

When does buying make sense?

Buying tends to be worthwhile when: you plan to live in the same place for 7–10+ years, the price/rent ratio is low (< 20), you have employment and financial stability, and the mortgage rate is moderate. If there is uncertainty about where you will live or your job situation, renting gives more flexibility.

The break-even point

The break-even point is the number of years after which buying is cheaper than renting in cumulative terms. It depends on all the above factors and can be calculated precisely using our rent vs. buy calculator.
