Did you know that a small change in the terms of your loan can multiply your monthly payments unexpectedly? Many people overlook key details when signing, such as the loan to value, which can make the difference between a secure loan and a risky financial commitment. That’s why understanding risky mortgages is more important than it seems, especially in the current economic context.
As a real estate agency specializing in the sale of exclusive homes with services for sales, rentals, new developments, investment, and comprehensive real estate advice, at Proddigia we help you understand how loan to value affects the security of your mortgage: we explain what risky mortgages are, why loan to value (LTV) is key, and what the current market picture in Spain looks like.
What is considered a risky mortgage?
A risky mortgage is one where the chances of financial strain for the borrower are higher than usual. In practice, it is considered higher risk when the transaction crosses certain prudential thresholds: high loan to value, income tight relative to the installment, variable interest rates during periods of increase, currencies other than the euro, or when clauses impose additional burden on the client. Learn about the current situation of risky mortgages and how loan to value makes the difference in protecting your finances.
What is its relationship with loan to value (LTV)?
Loan to value is the ratio between the loan amount and the appraised value of the property. An 80% LTV means the bank finances 80% of the value and the buyer contributes the remaining 20% through savings and expenses. When loan to value exceeds 80%, the lender assumes more exposure because the client’s capital cushion is smaller; and the buyer, in turn, is more exposed to price corrections or unexpected costs.
In Spain, the usual benchmark for standard financing is ≤80% LTV. Above this threshold, the transaction is classified as more demanding and is closely monitored by banks and regulators.
Difference from traditional or standard mortgages
- · Down payment: in a standard mortgage, the buyer usually contributes at least 20% of the value, plus taxes and expenses. In risky mortgages, own capital is lower and the loan to value rises.
- · Terms: traditional mortgages generally follow prudent policies (LTV ≤80%, effort ≤35%). Mortgages exceeding this framework may require guarantees, extra linkages, or additional insurance.
- · Expected volatility: with less margin, mortgages with high loan to value are more sensitive to changes in rates, appraisals, or household income.
Risks associated with these mortgages
When taking out your mortgage, it is important to consider the following risks:
Financial risk: increased installments and debt
Although fixed-rate mortgages dominate today, a high loan to value increases the total installment because the principal is larger. If the mortgage is variable or mixed, an increase in the reference rate or spread could pressure the household budget. Additionally, if the household is already near 30–35% effort, any rise can strain finances.
Foreclosure risk: losing your home
When LTV is high, the margin to sell quickly without losses narrows. If the household falls behind on payments and the market cools, liquidating the property to settle the debt can be more complicated. Loan to value matters because a drop in the sale price may not cover the remaining principal and associated costs.
Currency risk (in multi-currency mortgages)
If the debt is referenced in a currency other than the euro, exchange rates can work against you. A high LTV combined with a volatile currency introduces double exposure: variation of the outstanding principal in euros and variation of the monthly installment.
Legal risk: abusive clauses and contractual issues
In the past, clauses affecting transparency or risk allocation were detected. Although today the market is clearer, it is advisable to review: early maturity, late payment interest, fees, linked products, or any condition that alters the balance of the transaction. With high LTV, the lender may require additional guarantees (collateral, pledges), which should also be fully understood.
Current situation of risky mortgages
In the second quarter of 2025, 11.7% of new mortgages exceeded 80% loan to value, almost double the level at the end of 2023 (6.1%) and the highest record since 2019.
Additionally, the average LTV is now around 65%, close to the historical series maximum (66.5% in 2018). Even so, the theoretical burden of installments on disposable income remains around 33.5%, within the prudent 35% threshold.
Regarding mortgage delinquency, it remains contained: 3.32% at the end of 2024, with expectations to close 2025 below 3% if growth and employment are maintained.
What is driving LTV upwards
- · First-time buyers with greater financing needs in an active resale market and rising prices.
- · Public guarantees for young buyers covering up to 20% extra, allowing effective financing close to 100%; family guarantees are also included.
- · Gap between salaries/savings and property prices, requiring higher loan amounts and raising the average LTV.
How banks operate with higher LTV
There is no uniform practice: some institutions finance up to 90% of the price if the mortgage represents at least 80% of the appraised value, more common in new developments and under tightly monitored internal policies. These operations consume more regulatory capital, so they are not widespread and banks avoid taking unnecessary risk.
Why the increase is not considered alarming
- · We are far from the peaks of 2008 and 2013, when mortgages >80% LTV approached 18% of the total.
- · Fixed-rate contracts dominate, stabilizing installments and reducing the risk of hikes.
- · Household effort remains below 35% and delinquency is controlled, as long as the economic cycle and employment remain stable.
Expert insights and illustrative cases
Industry analysts point to a higher presence of first-time market access (when the household shows repayment capacity, banks can be slightly more flexible without abandoning prudent criteria).
There are also occasional cases where the bank grants more financing if the client demonstrates future liquidity (e.g., a committed inheritance to pay down principal in following years).
Signals to watch in the next 12–24 months
- Weight of mortgages >80% LTV: growth requires monitoring to avoid past mistakes, though fixed/mixed products dominate today.
- Macro and employment trends: deterioration could pressure delinquency and effort. Economists see growing uncertainty from 2026–2027.
- Property price vs. income/savings: if the gap persists, the average LTV may remain stressed.
Secure mortgage, smart decisions
At Proddigia, we believe that understanding loan to value helps you measure the financial leverage of your mortgage and, with it, the safety margins throughout the life of the loan. The Spanish market has seen the share of transactions with LTV above 80% grow, while household effort remains below 35% and fixed-rate contracts dominate—two elements providing stability. Still, increasing loan to value raises the buyer’s exposure, so each decision should be carefully analyzed. Our team supports you in making the right choices: from studying your mortgage to financing strategy and negotiation. If you are considering buying and need expert guidance, request a consultation and we will help you develop a safe plan tailored to your goals.
