How to Address "Mold" Comment from Tenant

[Scott J.]

I was at my single family rental last week to sign the tenant's second one-year lease. They've been great--no issues at all. While I was there I asked, "How's everything with the place? Everything working as it should?"

She said, "Yes, pretty much. Although it smells a bit moldy under the kitchen sink." She didn't sound worried at all. But I'm being cautious since mold is such a big buzzword. It's really unlikely, but I want to make sure my bases are covered from future issues, or worse, liability.

So we inspected under the sink. It is just like every other cupboard under the kitchen sink. Not the freshest smell, but not horrible either. But no real visible signs of mold.

How should I address this issue? I'm thinking maybe spraying something under the sink and sending a text to her (so it is in writing). It's sort of a hassle, since the property is 30 minutes away. But I'll do what is reasonable to protect my investment and the tenant.
