Ok so me and my partner, both 21 nearly 22, and are looking into buying first time. We have a nearly 3 year old together and I am 33 weeks pregnant with DS2. We are due to get married in july. Anyway..we have no savings and no deposit saved up..my partner has a good job, electrician and brings in a basic of about 30,000 a year, with overtime an average of around 34,000. This is before the dreaded tax. A month he gets 1800 after tax. We are looking into getting a house on the goverment mortgage scheme, basically the government pays 20% which is the deposit and the rest is the mortgage, this works out at 500 a month (we have found a house) for 5 years and then goes to 550. Paying back mortgage and government. I am a student, paramedic student but just started, another 5 years to go! Anyway what I'm asking is after all our bills (we are not in debt and everything we own is ours) after bills and childcare whilst I'm studying, we have 270 spare a month. That includes house insurance and what not being paid. Is 270 spare a month enough? We are going to try see if wed still get accepted by extending our mortgage to 35 years instead of 30 to reduce the amount we pay each month to 400, if this is done, then we are paying the same in rent as we would mortgage.opinions?
