What is the difference between a mortgage and a loan?

The term loan is broader. It denotes any form of lending of money against repayment and interest, with or without collateral. A consumer loan for furniture, a business loan for working capital, or an overdraft on a personal account are all loans, just like a mortgage. The decisive difference lies in the collateral: many loans are unsecured or secured only by movable assets, whereas a mortgage is always tied to a specific piece of real estate.

This difference in security affects terms and risks. Mortgages typically have lower interest rates and longer terms because the mortgage lien gives the bank strong protection. Unsecured personal loans are riskier for the bank and therefore more expensive; they also often have shorter terms and are amortized in fixed installments. For mortgages, in addition to the interest rate, the loan-to-value ratio (mortgage relative to property value) and affordability (debt burden relative to income) play a central role.

There are also differences in structure. Mortgages are often arranged in tranches, for example a first-lien and a second-lien mortgage, with different amortization requirements. Common options are fixed-rate mortgages with an interest rate fixed for several years or money-market–oriented models such as SARON mortgages with periodically adjusted interest rates. Traditional loans outside the mortgage sphere tend to follow standardized installment plans or flexible limits, for example with an overdraft facility.

The closing process is more formal for mortgages. The bank not only checks creditworthiness and income but also assesses the property, creates the mortgage security and has the mortgage deed registered in the land register. For an ordinary loan, a credit check with proof of income is often sufficient, without an entry in the land register. Accordingly, closing costs are higher for mortgages, but the financing amounts are typically much larger.

In practice this means: if you want to finance home ownership you need a mortgage, because only it provides the necessary volumes at manageable conditions. For short-term or smaller financing needs, such as bridging until funds become available, another type of loan may be more appropriate. Both instruments are loans in the broader sense, but they differ significantly in security, purpose, cost, term and legal framework.
