We live in London, so house prices are high. We like one house on the right move and can afford easily on our current salaries. In our area bigger houses are still selling fast but ours is a small 3 bed house with a small garden so may take some time to sell. The question is can we use money for deposit from our current mortgage (80% equity)and sell our house later. Would the estate agent take us seriously if our house is not on sell yet.
