The equity position can be put aside at the moment --- can you afford the mortgage repayment ? What are rent prices like in your area ?
Once off the property ladder it can prove extremely hard to get back on, especially with prices rising and incomes remaining stable (ie not increasing at the same rate as the prices).
My opinions are merely that .. opinions based on experience. Always seek professional advice.
