Most " second homes" are small wooden shacks on a dzialka or maybe for the upper classes a small flat on the coast.
Nah. They have second flats and hire it to someone. Whenever I hear about some parasite making a living this way, I feel an urge to punch someone. These thieves should be taxed into oblivion (this is the civilised part of me speaking, the other part wants this scum burned at the stake). Burn at the stake all the landlords, the scum of the earth.
