Inheriting Tenants and repairs needed

[Courtney Sorrell]

Good afternoon BP'er's, I'm a newbie looking for your wisdom!

I'm closing on an up/down duplex at the end of the month, both units occupied. The inspection looked good overall but the downstairs bathroom has a pretty good leak going from the toilet through the subfloors and into the foundation that I can see. The inspector noted that the bathroom floor is off-level and feels squishy, and recommended immediate remediation (new subfloor, etc).

The problem is that the tenant in place just resigned and will be there until next March, so now I'm wondering what I can legally do. What would you do?
