Thank you for the responses so far….

I have pre-approval for the loan, pending a valuation.  But in the application nothing was mentioned about Serviced Apartments because it was not an issue at the time of applying.  Whether that's going to be a problem now…. I am not sure.

I have fired off an email to my Solicitor about this, when I first heard, it certainly crossed my mind that this would be a breach.  But I thought as the developer is so big, that surely they wouldn't make a mistake like that if it was a breach….

Will see what the Solicitor says anyway….
