Enness International has received over £1.3bn of international property enquiries since September 2016.
Enness said demand was booming in Monaco (pictured) in particular, where the average loan size is €18m (£15.7m) compared to €6m (£5.2m) in Paris and €7m (£6.1m) in the French Riviera.
Monaco property is especially sought after by high net worth investors due to the principality’s status as a tax haven and lack of space.
Hugh Wade-Jones, managing director of Enness International, said: “We have been involved in the financing of international property for a while now but the response to the official launch of Enness International and opening of our Monaco office has been fantastic.
“As well as a huge number of big ticket residential deals throughout Europe we are currently working on two iconic development deals in Paris, which are extremely exciting for Enness to be part of.”
He added: “While the market is controlled by the prestigious Monaco private banks, we’ve seen the emergence of smaller banks based in Monaco and globally.
“Another indication of increased demand for Monégasque mortgages.”
Monaco accounts for 18% of all Enness International’s enquiries, which is still less than than the French Riviera’s 24%.
