Ok that's perfect regarding the interest. It's not going to cost me more than it would have.
On the job front - it's not an angle I really want to explore as I like my current job, but if it was a legitimate option I may consider it. The CAT manual states that if you are require to relocate abroad or in the state, that the clawback won't apply, - now I don't have to relocate, it's more of a want, for personal reasons.
I've been told that I'm legally allowed to purchase another property if I so wish without impacting the exemption, but my current home just has to be my main home, again it's not clear what "main" means - if I spend 7 months of the year here and use the other property as a holiday home, is that ok? My current job requires me to be on site, so that's why it won't really work,, and if I'm moving jobs well I might as well explore the employment query.
