LLC Property Questions

[Liz Lynn]

Not sure if this is the right category, but I would like some input. I have an LLC from my pet care business that I recently closed. The accounts are empty yet still open and the LLC is still in good standing, so could I now use it for investing in properties rather than buying a separate LLC?. I want to know if buying an investment property under the LLC is a legal, good idea considering it is registered for pet care industry work. Furthermore, should I get a new LLC for each property? TIA
