The tie up will see AToM offer the deals without lender arrangement fees for a limited time.
Dale Jannels, managing director at AToM, said: "AToM has worked in the Ex-Pat arenas for many years and has arranged mortgages for those all across the world.
“We realise that many customers have left the UK, yet they wish to purchase property or refinance existing loans whilst abroad.
“We are grateful to be able to offer a limited opportunity to Ex-Pats up to 75% LTV, interest only and for a limited time, with no lender arrangement fee.
“This is saving some customers up to 2% in fees compared to what's currently in the market. It's a great offering and there are no limits on the number of properties owned.”
Product details include a 4.49% 5-year discount, 4.99% 3-year fixed and a 5.49% 5-year fixed.
Jannels added: "This is an exciting opportunity for Ex-Pats but the product fee free element won't be around for long, so do contact us asap if you have customers who might fit this deal."
