Tenant is out of state and we need to get lease signed. Help.

[Kevin McDonald]

I have a tenant who is relocating to my area who is interested in renting my house.  I have met them and ran credit and background checks and all is good.   Trying to determine what options are available/legal for them to sign the lease agreement as they are not planning on returning to the area until the day of move in.   I was thinking of signing my portions in front of a notary, mailing it to them and having them sign in front of a notary as well and then having them return the document to me via track-able mail.   They are willing to do what ever is necessary, but I want to make sure it is being done legally for CYA purposes.  Any suggestions or comments are appreciated.  

Thanks!
