It is not always easy to put a price on rental properties. Every owner wants to find the perfect tenants who can take care of their house but they do not know how much rent they should ask for. After all, they think "what is the most reasonable price for renting my house?". You have to think of a specific figure that will be worth your while so the best thing to do is to establish what the actual or approximate rental value is.
One decisive factor that must be taken into account is the area where the property is located at. In fact, if the area is central, its rental value can be increased by up to 40%. People who want to rent in Madrid seek utmost comfort and prefer to look for a property that is in the centre of the city, even if the subject property is in worse condition than the one outside town.
