Types of Mortgages and How to Choose the Right One
Fixed vs. variable rates, fixation period, LTV, purpose-bound and non-purpose mortgages, refinancing, and early repayment — clearly and practically.

A well-chosen mortgage is one whose fixation type, repayment term, and LTV suit your situation and risk tolerance — not the one with the lowest number in the ad. Before comparing rates, clarify how long you'll stay in the property, how much you'll put down from your own funds, and how much certainty you need for a stable monthly payment.
A mortgage is the most expensive product you'll ever sign — differences in conditions add up to tens of thousands of euros over the repayment period. It's worth understanding a few basic concepts so you don't decide based solely on the interest rate in the brochure.
Fixation period: what you trade for what
| Fixation | Typical rate | Payment certainty | Early repayment fee | Who it suits |
|---|---|---|---|---|
| 1 year | lowest or near it | minimal | lowest | those expecting rate drops and tolerating risk |
| 3 years | lower | medium | low | a compromise between price and peace of mind |
| 5 years | medium | good | medium | most common choice |
| 7–10 years | higher | highest | highest | those who want a guaranteed payment for the entire period |
| Variable | derived from market rate | none | typically no fee | those planning to repay early |
The end of fixation is the only moment you can refinance without penalty. Note the date — your bank will remind you only a few weeks before.
Fixed vs. variable rate
This is the first and biggest choice. It determines whether your payment will remain unchanged for a period or fluctuate with the market.
- Fixed rate is locked in for an agreed period (fixation period). Throughout that time, you pay the same amount regardless of what happens in the market. Advantage: certainty and a predictable budget. Disadvantage: if rates drop significantly, you're locked in at the higher rate until the end of fixation.
- Variable (floating) rate changes over time according to a reference market rate. When rates fall, you save; when they rise, your payment increases. Advantage: often a lower entry rate and usually more flexible early repayment. Disadvantage: uncertainty — your payment can jump.
The vast majority of borrowers choose fixed rates precisely for the certainty. Consider variable rates mainly if you have reserves, can absorb payment fluctuations, and believe rates will drop.
Fixation period: how to choose it
With a fixed rate, you also decide on the length of the fixation period. There's no universally "best" length — it's a trade-off between certainty and flexibility.
- Shorter fixation (roughly 1–3 years): you reach repricing sooner, so if rates drop, you benefit faster. The price is higher uncertainty and more frequent negotiations.
- Longer fixation (5 years or more): extended peace of mind and predictability for years ahead. The downside is that it locks you in — if rates drop in the meantime, you wait until the end of fixation or pay for early repayment.
Practical guidance:
- How long will I stay here? If you plan to sell the property soon, a shorter fixation makes sense.
- Where are rates now? When rates are historically high, people often choose shorter fixation hoping for a drop; when low, they like to lock in longer certainty.
- How well do I tolerate uncertainty? If the idea of a sudden payment change stresses you, pay extra for longer certainty.
LTV: how much you borrow relative to the property's value
LTV (from loan-to-value) is the ratio of the loan amount to the value of the mortgaged property. If a flat is worth €206,000 and you borrow €164,000, your LTV is 80%.
Why it matters:
- Lower LTV = lower risk for the bank = usually better rate. The more you put down from your own funds, the better for you in terms of interest.
- Own funds (down payment). The bank will want part of the purchase price from your own savings. The more you save beforehand, the smaller loan you need.
- Regulation. Maximum permissible LTV and other indicators (e.g., debt-to-income ratio) are governed by the central bank's rules and each bank's internal policy. These limits change over time and vary depending on whether it's primary residence or investment property. Always check current limits with your bank or a mortgage advisor — don't rely on figures from articles, they may be outdated.
Mortgage payment
Monthly payment, total interest and balance after fixation
Indicative estimate only — actual figures depend on your market, contract and provider.
Purpose-bound vs. non-purpose mortgage
Mortgages are also divided by whether the bank monitors what you use the money for.
- Purpose-bound mortgage must go to a specific purpose related to housing — typically purchase, construction, renovation, or buyout of a co-owner's share. You document the purpose to the bank (purchase contract, construction budget). In exchange for this "monitoring," you get a lower interest rate.
- Non-purpose mortgage (often called American-style mortgage) doesn't restrict the use — you can spend the money on almost anything, but you pledge the property as security. The price for this freedom is a significantly higher rate.
The conclusion is simple: if you're financing housing, choose a purpose-bound mortgage — it's almost always cheaper. Consider non-purpose only when you need flexible funds and don't mind paying more.
Refinancing: when to move your mortgage elsewhere
Refinancing means repaying your existing mortgage with a new one — either from another bank or from the same bank on better terms. Most often it happens at the end of fixation, when the transition usually comes without penalties.
When to consider refinancing:
- There are noticeably lower rates on the market than in your contract.
- Your fixation period is ending and your current bank offers worse terms than competitors.
- You want to change loan parameters (repayment term, payment amount).
How to decide — do a simple calculation:
- Calculate how much you'll save on payments over the new fixation period.
- Subtract costs of the move (property valuation, fees, possible notary or land registry expenses, and your time).
- If the net savings are significant, move the loan. If it's just a few tenths of a percent, it may not be worth it.
Tip: even without switching, try to negotiate better terms with your current bank — a competitive offer in hand is a strong argument.
Early repayment: what to expect
Early repayment means you pay more than your monthly obligation or settle the entire mortgage ahead of schedule.
- At the end of fixation, early repayment is usually penalty-free — that's the ideal window for full payment or refinancing.
- During fixation, the bank may charge a fee. Its size typically depends on the prepaid amount and years remaining until the end of fixation, plus administrative costs. Exact rules and caps change over time according to consumer credit law — don't rely on specific percentages from articles and check your contract and with the bank.
- Legal exemptions. The law provides for situations where no penalty is charged (for example, serious life circumstances or sale of the financed property after a certain period). If one of these exemptions applies to you, discuss it directly with the bank.
Most mortgages also allow smaller voluntary additional payments without charge within the contract anniversary period — use this for gradual repayment without fees.
Frequently asked questions
Is fixed or variable rate better?
It depends on your risk tolerance. Fixed rates give certainty of the same payment throughout the fixation period and work well if you want peace of mind and a predictable budget. Variable rates change with the market and can be cheaper, but also more expensive. Most borrowers choose fixed rates for the certainty.
What fixation period should I choose?
Shorter fixation (e.g., 1–3 years) offers flexibility and a chance to refinance sooner if rates drop, but with higher uncertainty. Longer fixation (5 years or more) brings extended peace of mind, but locks you in with one bank. Match the fixation length to how long you plan to stay in the property and how much certainty you want.
What is LTV and why does it matter?
LTV (loan-to-value) is the ratio of the loan amount to the property's value. The lower your LTV (i.e., the more you put down from your own funds), the lower the risk for the bank and usually the better your rate. Specific maximum LTV limits are governed by the central bank's rules and your bank's policy — always check current figures with your bank or advisor.
What's the difference between a purpose-bound and non-purpose mortgage?
A purpose-bound mortgage must be used for a specific housing-related purpose (purchase, construction, renovation) and you document it to the bank — in return, you get a lower rate. A non-purpose (American-style) mortgage doesn't track how you spend the money, but is more expensive. If you're financing housing, a purpose-bound mortgage is almost always cheaper.
Is mortgage refinancing worth it?
It can be worth it at the end of your fixation period, when switching to another bank is usually penalty-free and you can get a better rate or terms. Calculate how much you'll save on payments and subtract costs (valuation, fees, notary or land registry expenses, your time). If the difference is only a fraction of a percent, it may not be worth moving.
How can AI help me choose property?
AI assistants like ChatGPT, Claude, Perplexity, or Gemini can compare offers, explain terms, and calculate payment scenarios. If you're selling or looking for property, it helps to list where AI can read — for example, on the open platform AssetLog (assetlog.ai) — so when a buyer asks AI for recommendations, your listing can be found.
