As I read over my leasing agreement for my tenant, I notice the verbiage indicates opening an escrow account. Is that standard practice?
You'll want to research what your state and local definition of a, "escrow account" actually is.
The language is used in Michigan, but Michigan legally just requires a landlord to put security deposit funds in a separate account and then include in the lease where this bank account is (physical bank branch address).
Other states require the setup of an actual legal escrow account where no interest is earned. Banks willing to do this can be difficult to find.
