We've agreed a (very small) reduction in our sale price.
The house I am buying is worth considerably less than the one I am selling and as a result my mortgage is decreasing, not increasing. The sale price reduction is very small in relation to any of the figures in question here (for arguments sake, it's a £5k drop on an almost £1m house; new mortgage in the region of £150k).
Am I obliged to tell my mortgage company?
