to buy a house I can't afford?

[blinkineckmum]

I am hoping to put in an offer on a house as it's the right place and right timing for various reasons. I am usually really cautious with money, and have a smallish mortgage on my current house. The house I want to buy is just about affordable, but I would double my mortgage debt and repayments. I could just about do it, but it's a huge house, and it would all be much easier if I rented out a room or even a floor. AIBU to consider buying this house, if I can only comfortably afford it by having to rent some of it out? Thanks for any opinions

shame! But similar happened to us (we also increased mortgage payments to double the previous payment) and a few weeks later the agent was back on the phone as the earlier sale had fallen through. We definitely struggled at first with the additional costs, despite my careful budgets, but our childcare costs went down and our incomes up. I am glad now we took the plunge as our DCs are going into their teens and, as pp have said, they take up loads more space and also want their own space.
