Create a "For Sale" sign. You can do this yourself or preferably buy one. This results in enquiries.
You can list your property on sites that advertise private property for sale, in newspapers (which is cheaper than you might think) and by word of mouth.
• Take good, well lit, pictures showing off your properties best assets and views.
• Take time to write a short description of your property, too long and people won’t read it all, but make sure you SELL it. Add any selling points, terraces, views, talk about the neighbourhood, social events, shops etc, how far it is to the airport etc. If you can provide a video clip then state this as this is obviously highly beneficial and you can email this to enquirers.
• Facilitate viewings on as short a notice as possible. If you leave your keys with a neighbour who plays golf three times a week, you might be losing a vital chance to show the property at the buyers convenience.
• Ensure that curtains and shutters are open and lots of light floods the property when it is shown.
• If there are any small repairs or repainting that would enhance the overall appeal of the property, it's well worthwhile getting this work done. Although it goes without saying, a clean house is a desirable house, and many buyers are put off if the property is grubby or untidy. Make sure the place is spotless and you will instantly create a favourable impression.
• If you intend to sell your property with some furniture, it is most important to make an inventory right at the beginning and list these. Many a sale has been on the brink of falling though when a buyer thought that the painting over the fireplace was included, and felt that the seller was "too mean" when he learned that it was not! Negative energy during a negotiation can be avoided by having a clear inventory in writing from the outset.
• Remember that selling a property in a resort area is not usually a rapid procedure, even in good market conditions. Properties can stay on the market from three months to 2 years, depending on the market, the location, condition and general desirability of the property, the effectiveness of the sales strategy and, of course, the asking price.
• Points to consider when a negotiation is taking place: Is the buyer expecting a counter offer from you or has he given you a one-and-only, take-it-or-leave-it offer? Does he have other properties in mind if he doesn't buy yours? Is his offer a fair one? Are all details included in the offer -- price, target contract date, deposit, completion date, precise understanding of what is included in the sale in the way of fixtures, fittings and furniture, and who pays the municipal "plus valía" tax? These items should be agreed upon at the outset and before lawyers are instructed and above all, should not be negotiated "piecemeal", to avoid unpleasant surprises.
• Once you make up your mind to proceed, and with an understanding of "emotional factor" of the buyers of second or retirement homes, where they can change their minds abruptly, move quickly (but surely) to close the deal.
