At todays interest rates the repayments would be slightly higher than the rent you are paying, but long term property is a very sound investment, a few things to consider are, you have to pay for repairs, and insurance, but on the positive side, you can decorate how you like change whatever you want,I would buy,I have bought and sold lots of houses and think property is a far better investment than pensions, some building society websites might have a calculator to find repayments,if you do go for it, I would say get a fixed rate for at least the first 3 years,then you can budget ,you will know exactly what outgoings you will have , good luck, Ray
