Newbie - buying a property already having a business housed in it

[Roy Mitle]

Hi

First time on the forum so I am hope I am on the correct board.

I am buying my first investment - SFH in which the owner was running his own business treating patients. Owner went into foreclosure. now its a REO property. Bank only cares about selling it for max price. its upto me to have the owner as tenant or not.

I plan to keep the tenant. the numbers work out well. the rent is quite high and he want to continue to run the business at the place. so i don't have to find a new tenant.

Are there anything I need to be careful about? Will I have to be liable for his business -eg he doesn't pay his biz tax and I get into trouble.
