sending cash overseas and keeping it until close

[Javier S.]

Hi,

I was planning to send some money to my Costa Rican parents to buy my share of a rental in Costa Rica.  The money will be sitting in my parents' bank account until it is used for the closing (let's say a couple of weeks or a month).  Are there any restrictions from the US government or IRS or anything I have to be aware of?  It is not a gift to them, they will just hold the money until we close on the rental.  

Thanks.
