Ah, see, that's where I worry. I don't want to ask for too much information and put them out when I have zero intention of buying these properties and just want the information for my own study.
Inheriting tenants appeals to me but I can see there might be disadvantages too. Perhaps they're a problem tenant the LL hasn't dealt with since they were planning to sell, or the LL has been absentee lately due to circumstances related to selling (trying to retire, illness of a spouse, etc.) so the relationship and attitudes may not be good, or maybe the LL is secretly cutting them a deal to get them to stay until the property is sold, etc.
