Qu'est-ce que le/la Quotité de financement (LTV) ?

Le ratio prêt/valeur (LTV) exprime le rapport entre le montant de l'hypothèque et la valeur expertisée du bien en pourcentage et sert à la banque pour évaluer le risque du crédit.

LTV is the single most important risk metric in mortgage underwriting. A lower LTV means the borrower has more skin in the game and the lender has a larger equity cushion if the property must be sold in distress.

In Switzerland, banks lend up to 80% LTV on owner-occupied homes (first mortgage 65%, second mortgage 15% which must be amortised in 15 years or by retirement). US conventional loans above 80% LTV trigger PMI; below 80% it can be dropped. UK lenders price mortgages in LTV bands — every step down to 75%, 60% or 50% unlocks a lower rate.

Formule
LTV = Loan Amount ÷ Appraised Property Value
Exemple

Buying a CHF 1,000,000 property with a CHF 200,000 down payment and an CHF 800,000 mortgage produces an 80% LTV — the regulatory ceiling for owner-occupied homes in Switzerland.

Questions fréquentes

What is a good LTV?+

Below 80% unlocks the best rates and avoids extra insurance (PMI). Below 60% earns premium pricing in many markets.

How is LTV different from equity?+

LTV is loan ÷ value; equity is value − loan. They are mirror images of the same balance sheet.

Does LTV change over time?+

Yes — it falls as you amortise the loan and as the property appreciates.
