Buying in cash or with a mortgage in Mallorca: which is better?

This is one of the questions clients ask us most, and the short answer is always the same: it depends on what you're looking for. Buying in cash and buying with a mortgage aren't "better" or "worse" in the abstract — they optimise for different things. One maximises safety and return on the money invested; the other maximises the total growth of your wealth from the same starting capital.

In this article we compare both options on the same deal, with numbers, so you can see exactly what changes in each scenario.

The obvious advantage of paying cash

Paying in cash has three advantages that don't show up on any spreadsheet:

• Faster, simpler completion: no bank valuation, no credit assessment, no waiting for committee approval. In a low-supply market like Mallorca's, this can be decisive for winning a deal.
• Negotiating power: a seller will almost always prefer an offer with no financing contingency, because it removes the risk of the deal falling through at the last minute. It's common to negotiate a better price in exchange for paying cash.
• Zero financial risk: there's no instalment to pay no matter what happens with the rental income, and no exposure to rising interest rates.

Why leverage can supercharge your return

A mortgage has an advantage that's often overlooked: it lets you buy a €300,000 asset by putting down only part of that money, while keeping all the future appreciation of the entire property — not just the portion you paid for.

This is financial leverage, and it's why, on the same property, the IRR with a mortgage usually ends up higher than the IRR paying cash, even though the monthly cash flow is lower. You're using the bank's money to buy more appreciation than your own capital alone could buy.

The other side of the coin: risk

Leverage multiplies good outcomes and bad ones equally. If the rental income stops for several months, with a mortgage you still have to pay the instalment; in cash, you simply stop earning, with no further consequence. And if you ever had to sell at a bad moment in the market, the outstanding mortgage reduces what's left for you after the sale.

There's also a cost you pay every month, rain or shine: interest. The higher the interest rate, the less sense it makes to finance rather than pay cash — especially if you have the capital available without having to give up other investments.

Taxation matters too

If you rent out the property, mortgage interest is a deductible expense for income tax purposes, just like council tax or community fees. This reduces the real cost of financing relative to the nominal interest rate — another reason why, for an investor, a mortgage isn't simply "expensive money" compared with cash.

Practical example

Let's take a €300,000 flat in Mallorca, with €30,000 in purchase costs (transfer tax, notary, land registry and legal fees), and compare buying it 100% in cash versus financing 70% at 3% interest over 25 years:

Item	Amount
Purchase price	€300,000
Purchase costs (transfer tax, notary, land registry, legal fees)	€30,000
Total investment	€330,000
Estimated monthly rent	€1,400
Gross annual income	€16,800
Annual running costs	€2,200
Gross yield (same in both scenarios)	5.1%

Metric	Cash	Mortgage (70%)
Equity required	€330,000	€120,000
Annual instalment	—	€11,950
Year 1 cash flow	€14,600	€2,650
Cash-on-cash return	4.4%	2.2%
Estimated 10-year IRR (3%/year appreciation)	5.8%	9.1%

The result sums up the dilemma well: in cash you net €14,600 the first year, versus just €2,650 with a mortgage — a huge difference day to day. But over a 10-year horizon, the mortgage IRR (9.1%) clearly beats the cash IRR (5.8%), because that financed 70% has also appreciated by 3% a year, and that growth is entirely yours even though the bank put up most of the money.

When does cash clearly pay off?

• When you need to close quickly or are competing with other offers.
• When the available interest rate is high relative to the property's expected return.
• When you prioritise safety and monthly cash flow over long-term growth.
• When you're a non-resident and access to financing in Spain is limited or expensive for your profile.

When does a mortgage clearly pay off?

• When the goal is growing total wealth, not maximising monthly income.
• When the interest rate is reasonable and well below the property's expected appreciation.
• When you'd rather keep liquidity to diversify across more than one property, or into other assets, instead of concentrating it all in one.
