How to manage expenses paid for on my behalf by someone else?

[Steve S.]

I had a family member on one of my rentals make several purchase for a house i bought out of town (but in town for them).  

The total expenses added up to about $4,000 across several different purchases. 

Is there anything special I need to do from a tax perspective?  They have receipts for most of the purchases and I will be reimbursing them for the full amount.  

Thoughts?
