If an agent is advertising a condo for sale and for rent at the same time, are there any issues with leasing this condo as a tenant? Say you enter into a 1 year lease, then later on the owner sells it, are you legally protected that the new owner has to continue leasing to you for the full term of the lease, and that the old owner won't run off with your deposit and you will get your deposit back at the end of the lease term?
