£7k estate agent fees to sell, 3% stamp duty to buy so about £10k, and then legal fee's... add on all the little bits like getting stuff in storage short term till we sell, EPC fee's blah... blah...blah... Expensive shizzel...
My best friend is an Estate Agent. She always tells her friends to never pay the standard commission fee that Estate Agents charge. They'll tell you their commission is fixed but it isn't. Most would rather have 1% of something than 1.5% of nothing. Do not pay more than 1% commission. Ever.
