Power of Attorney if you are out of the country. If you are in the US ask the title company to arrange a mobile notary to bring the closing papers where ever you are. If they say they can't then just tell them to get in touch with a mobile notary called Docpros.net. They are really good and have used them several times nationwide.
There are a few ways you can handle this, you can appoint someone to carry out your role with a Power of Attorney or you can have your escrow officer send documents to you. Either way you can have funds electronically transferred to your account regardless of where you are. I would think having a power of attorney drawn up would add more costs to you because you have to have an attorney do this and then it has to be filed with the court in the county where the transaction is closed. The only additional charges you will have by documents being sent to you would be for fedex, ups, etc. and a small fee for a notary. I suggest communication with your escrow officer, ask them the best and most effecient way to handle it.
You can be anywhere in the world and sell your property anywhere. As long as you have fax machine, computer. You can sign all the documents and notarized it and mail it back.
