I am a US citizen but live abroad. I have rental properties in the US. I need to visit my rental properties in person on a regular basis so I can evaluate the conditions of my rentals and the tenants, as well as meet with my property managers to discuss all things related to my rental properties.

Can I expense all the costs related to my travels solely to conduct rental activities, if I fly from overseas to the US ?

Travel expenses.

You can deduct the ordinary and necessary expenses of traveling away from home if the primary purpose of the trip is to collect rental income or to manage, conserve, or maintain your rental property. You must properly allocate your expenses between rental and nonrental activities. You can’t deduct the cost of traveling away from home if the primary purpose of the trip is to improve the property. The cost of improvements is recovered by taking depreciation. For information on travel expenses, see chapter 1 of Pub. 463.

To deduct travel expenses, you must keep records that follow the rules in chapter 5 of Pub. 463.
