Lenders use LTV to price risk: a lower LTV (a bigger down payment relative to the home's value) usually unlocks a better interest rate, since the lender has more cushion if the property ever needs to be repossessed and resold.

🇵🇹 Since 2018, Banco de Portugal has recommended banks keep LTV around 90% or below for a primary residence, and lower still (roughly 80%) for a second home or buy-to-let purchase. Confirm the current limits before planning a purchase around this figure.
