Sorry for the cheeky question. We're about to buy a house in London and we've seen two we like. One is more expensive but has a great granny annex in the basement (separate kitchen, living room etc). It occurs to me that because live in nannies are cheaper, we may be able to get the more expensive house and afford the extra mortgage with what we save in child care. Is this realistic? What is the difference in salary between live in and live out nannies in central London? I'd be really grateful if anyone can help.
Thanks
