I successfully rent out my apartment for about 25 weeks a year. Do not expect a massive return on Investment for a few years (and even then no better than a decent building society account.)
Get yourself a local person to clean and launder the place.
Advertise on the web. Try holiday-rentals, holidaylettings and owners direct to kick off with. Create your own website.
Price low. You want to get the punters in in the first year. Look at similar properties on these websites, look at their prices and then go in a tad lower.
I am registered with many agents and get no business from them. They’re useless and charge up to 30% of your rent.
