Estate Agents

Because time is money

We are well aware of just how busy the day-to-day life of an estate agent is. Pitching for new business, nurturing new client relationships while maintaining existing ones, growing and maintaining your pipeline and market share plus dealing with onerous administration. You are expert multitaskers.   

CSP understand the stresses and how much it takes to get a sale exchanged as soon as feasible. As a specialist extension to your existing team, your agreed sales are in safe hands. CSP will steer your sale in the right direction, keeping all parties fully informed, working through any potential issues in the transaction diligently and effectively, accelerating the sales process and reducing the chances of fall throughs. We have experienced and understand the emotions and sensitivities which can become heightened during the period between agreeing a sale and exchange. It can be a stressful process for buyers and sellers. We recognise the need for tact, diplomacy and sensitivity wherever it arises. This will enable you and the wider team to have the time and confidence to focus on your key business; growing revenue and expanding market share. Take the (un)fair advantage over your competitors.
