Tenant not paying gas bill

[Dave Versch]

Hi All,

I've got a tenant in a duplex that fell behind in his gas payments and the gas company shut their gas off. The tenant's lease is up end of June. I'm concerned that if I renew him and he doesn't get his gas bills straightened out by fall, I'd be running a risk that the pipes freeze and burst. (This is up in Buffalo, NY -- it gets cold early.)
So, to renew, or not to renew? Opinions?
