Before you can enter an occupied property to perform a rental inspection, ensure you’ve properly communicated beforehand with your tenants in compliance with your state’s notice to enter the property.
However, there are general things a landlord walkthrough checklist can account for:
Water leaks (sink, toilet, faucet, roof)
Water damage (walls, ceiling, floor)
Overall cleanliness/condition of property
