Expat here -- yes, that's a real problem. There are even well-located commercial buildings in central Lisbon that are decaying while things like that are sorted out. I honestly don't know why they don't do short-term (as in, three year or so lease) rentals while things are sorted out. Perhaps protections (regulatory or customary) in commercial leases that make it hard to get people out once an agreement has been reached between the heirs?
