When selling a property, you must collate all relevant documentation, regardless of whether you’re receiving third-party assistance. The easiest way to do this is to put together a file: receipts from any investments made within the last few years are important for the asking price and for property gains tax. In addition, banking documentation, an extract from the land register, plans, photographs and other relevant documents relating to the property should be collected in a file. An estate agent can help you with this. Based on this file, a selling price can be estimated and the sales documentation can be drawn up. Many sellers underestimate the complexity, the amount of time it takes to sell and the work involved: professional photo shoots, finding a buyer, arranging viewings, processing and negotiating the sale, and resolving financing and tax issues. All of this must be factored in when deciding whether to seek professional assistance from an estate agent.
