The overseas mortgage company says it is seeing an increasing trend among its clients who are considering refinancing.
The strength of the euro means that equity in second homes abroad is now worth much more when converted back into sterling.
Remortage rates start as low as 2.49% in sterling for properties in Portugal on a repayment basis at a maximum LTV of 70%.
Other rates include a 2.69% deal for Spanish property at 60% LTV and 3.09% in France at 70% LTV, both available on a repayment basis.
Clare Nessling, operations director at Conti, says: “Many home owners who have unencumbered properties, or who have seen some price growth since their properties abroad were purchased, are releasing equity to pay off debts back in the UK or to help buy UK property.
“Some are releasing cash to inject into their UK properties to bring down LTV ratios, especially if they’re hoping to switch to a new mortgage deal.”
She adds: “Others simply want to switch their overseas mortgage to a significantly cheaper rate and benefit from lower monthly repayments.”
