With a 20% market increase in a year, you don't have to rent it. Renting a property out always comes with hassle. Many countries have tenant's rights that kick in after a period of time.
I live in Barcelona, and the rental market is crazy. Technically I should be allowed to sign a contract for 5 years, but because of the rights that kick in after 12 months, there's a ton of landlords that only want to offer 11 month contracts.
