I have an apartment that I am thinking of selling either later this year or next year. At the moment I have a one year lease on it and it is registered with the RTB. The lease is up in July and tenants are leaving. I was thinking of renting now on a shorter lease maybe 3 months or 6 months as I am not sure when exactly I will be selling it. If I changed to a shorter lease what are the implications for the RTB. Would I have to register it with the RTB on a shorter lease?
