If you sell your house London, you will save a substantial sum (the typical estate agents fee is between 1.5 and 2 percent, which pays £2,250-£3,000 on a £150,000 property). The drawback is the time and work that you will have to put in yourself. If you try but fail to sell your house in London, you won’t save anything, but you still lose the time and the opportunity to move.
