Many people have used this route for hour building, and, if you choose the right aircraft, it can work out much cheaper and much more convenient than overseas hour building. Permit To Fly aircraft are particularly good for this.
In fact there are some people who have built to 1,000 hours after their CPL in single seater permit aircraft based at zero landing fee strips. If you're in a well-paying job this can actually work out cheaper than instructing when you look on a lost income basis and you're happy to go at it hammer and tongs over a couple of years around your day job.
One to watch for is minimum hours as some groups will not accept people with less that 100hrs TT (due to punitive insurance premiums).
cheers!
