What would you say is a reasonable amount of disposable income? Is it just that you want to have extra if you need to repair something etc. We're eager to get a mortgage, and have worked out we'd have £300 to spend after all outgoings (including food, petrol). Is that enough for a couple (with no kids)? We don't do much lol, take aways, cinema and not very often. OH has overtime some months, but I also worry about when we come to ttc if we're not earning much more. How much do you have after all bills, food, petrol etc?
