Have found a house we love and is on market for both rent and buying. We are not quite in a position to buy (our house is a guarantee sale to family member but family member hasn't sold as their offer fell through) but are hoping to be soon. So could we rent until we are ready to buy and is this possible? We would be struggling to afford more then two thirds of the rent it is on the market for and how does it work if a rent agreement is six months and we are ready after three. Our mortgage would be significantly cheaper then rent being asked for. The vendors are keen to move but not sure if it is worth is entering this conversation with them or do we just say what will be will be and leave it for a while?
