ČSOB Mortgage at a Glance
The ČSOB mortgage is a standard home loan offered by one of the largest banks in the Czech market. This review is based on the representative example that ČSOB publishes for this product, and is aimed at anyone who wants a quick, concrete picture of the real costs and terms before approaching the bank with their own application.
Interest Rate and APRC
ČSOB offers a fixed interest rate of 5.09% p.a. on this loan, fixed for 3 years. The rate stays unchanged during the fixation period, but once it ends the bank will offer a new rate based on market conditions at that time — a risk worth keeping in mind with such a short, three-year fixation.
The Annual Percentage Rate of Charge (APRC), which includes fees on top of interest, comes to 5.46% p.a. The gap between the nominal rate (5.09%) and the APRC (5.46%) is roughly 0.37 percentage points — which is why it's always better to compare offers by APRC rather than by the interest rate alone.
Total Cost
According to the representative example ČSOB publishes for this product, a loan of CZK 4,500,000 over 30 years (360 monthly instalments) carries a monthly instalment of CZK 24,405. Over the full term, the borrower repays a total of CZK 9,016,773 — roughly double the amount borrowed, which is typical for a 30-year loan given how long it runs.
This is a representative example under specific assumptions (loan amount, the rate in effect at the time of calculation, loan term) — an individual applicant may end up with different terms depending on their creditworthiness, the value of the collateral, or the bank's current offer. These figures are therefore not a guarantee of identical terms for every client.
Terms and LTV
The maximum loan-to-value ratio (LTV) at ČSOB is 80% — meaning the borrower needs at least 20% of the property's value in their own funds. The exception is applicants under 36, for whom the bank allows an LTV of up to 90%, meaning own funds of just 10% of the property's value.
The bank charges a fee of CZK 2,200 for loan drawdown and registering the mortgage lien in the land registry.
Pros and Cons
Pros
- LTV of up to 90% for applicants under 36
- Low fee for drawdown and lien registration (CZK 2,200)
- Fixed rate throughout the 3-year fixation period
Cons
- Short, three-year rate fixation only
- APRC of 5.46% p.a. — real costs are higher than the nominal rate suggests
- Standard LTV of only 80% (min. 20% own funds) for applicants over 36
Summary
In the published representative example, the ČSOB mortgage offers a fixed rate of 5.09% p.a. with an APRC of 5.46% p.a. over 30 years, with a monthly instalment of CZK 24,405 on a CZK 4,500,000 loan. It's particularly interesting for younger applicants under 36 thanks to the higher LTV of up to 90%. Before signing, though, it's always worth comparing the bank's current individual offer — actual terms may differ from the representative example, and the short three-year fixation means a rate change needs to be factored in within just three years.
