Sinclair moved to the Hawthorns on loan from Manchester City last summer but has struggled to hold down a place in the side and has featured just seven times this season.
Girlfriend Helen Flanagan told OK! Magazine: "Scott breaks up in about six weeks and we'll know in July where we're going next.
"With my work I can travel where I want to, and you want to be with the person you love.
"We don't know where we're going, but we won't be staying in Birmingham. We're actually building a house near London at the moment that will be ready by Christmas."
