With respect to mileage, expenses incurred to travel between your home and a rental property generally constitute nondeductible commuting costs unless you use your home as your principal place of business.
See https://www.irs.gov/publications/p527#en_US_2018_publink1000218991
Cleaning, maintenance, and repairs are generally deductible expenses, but an owner of rental property cannot deduct his/her time in performing those tasks.
