NAPLES, FL—There's been plenty of talk about the Canadian capital invasion, from investors to bank branches. The latest move comes from RBC Bank, a major Canadian bank that focuses heavily on serving Canadians visiting or making long-term stays in the US.

RBC just announced a partnership with Lennar Homes in southwest Florida to offer mortgages to Canadians buying homes there. The deal makes good sense, given Lennar is one of the nation's top home builders and Canadians are the top foreign homebuyers in the US.

Consider the statistics: According to the 2014 Profile of International Home Buying Activity by the National Association of Realtors, Canadians invested nearly $14 billion in US homes between April 2013 and May 2014. Simply stated, RBC smells the opportunity and believes its Canadian customers will buy into what Lennar-built second homes stateside.
