Martin Reynolds, chief executive of SimplyBiz Mortgages, comments: "Advisers should understand each lender's policy and the types of products/schemes they offer.

"Talk with the business development managers at each lender to be clear on what support they can offer."

He also advocates talking to specialist distributors, who may have access to smaller lenders, who could help in more complex buy-to-let cases.

Mr Landy agrees: "Be aware that BTL is rapidly changing, so partnering with a reliable, experienced master broker who can keep you abreast of the changes makes a lot of sense."

Moreover, Mr Reynolds adds: "Understand where you can guide clients to get the correct tax advice, and where they can find more information.

"It is always good to be proactive with your client bank, as they will need your guidance more than ever."
