Rental Property

[austinmtexan]

Can I write off my entire flight costs to visit my rental property even if less than 50% of my time will be spent on work vs vacation at the rental’s location? 

Also, I do not have any receipts to annotate my time spent working on the rental.

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.

That's irrelevant anyway. Since your time can not be taxed, there is no deduction for your time any way you look at it.
