mm, not surprised...
Why is that an issue? If what you're wanting is essentially insurance for the period *before* you sell, rent, or live in the property, what does it matter to the insurers what you intend to do with it afterwards?
If it is a sticking point, what's to stop you deciding now to rent the place out, but later on when all the work is done, maybe you have a change of heart and decide to flog it after all...?
Do keep us posted!
