Improvements with tenants in place?

[Jen Starr]

Hi! Wondering if anyone has ever updated a units electrical while there is a tenant in place? I'm closing on a property soon that has existing tenants who are paying well below market value. They'll eventually have to move but probably not until spring. The electrical in their unit is really bad, very few outlets, some ungrounded, just not good. The whole unit needs an overhaul but the electric stuff feels like something I want to address asap. Thanks in advance for any suggestions! Jen
