Notarized Lease Agreements

[Greg Franck]

My wife and I have always used a realtor to rent our condo.  This time around we wanted to pocket those associated costs.  We have found a tenant and I have built a solid lease agreement.  The question is do I need to have it notarized when the parties are signing or are the signatures tracked through a process like focusing appropriate?  Any feedback would be more then welcome and appreciated.  Thanks
