We have opportunity to purchase a quad plex for 455k. It’s a off market deal. I believe this is a whole sale deal so no inspections allowed per seller. Tenants in all 4 units. 1 owner since house built in 1975. Roof replaced in 2013. 2 newly A/C units. Rent under value averaging 4800 gross a year but market value is 60k. Is it normal for no inspection on whole sale deal? I see it as great opportunity but huge risk
