First house purchase. Chain free therefore things have moved at a swift pace. Mortgage in place, searches and full survey done. We want this house yet we've yet to talk with our landlord about our current rental agreement and the possibility of cutting it short. We can afford to pay both the mortgage and rent on our current place but were wondering what the etiquette is once we've exchanged contracts. Is it ok to ask for a completion date, say 6-8 weeks after exchange or is that just going to rub the vendor up the wrong way? It's been four weeks since we put our offer in and it looks like the contracts are ready to go out.
