Safety likely will be a top priority for any tenant you show a unit to. Ensure that each entryway is brightly lit and exterior doors have new locks and keys. This additional expense will be well worth it, as no one will rent a unit where they feel uneasy or unsafe.
Brighten entryways and patios with LED lighting, and remember to re-key locks.
Repair broken light fixtures, cracked paint, and torn screens.
When time permits, replace worn and outdated fixtures, doors, and flooring.
