Fungi - I am assuming you mean December 3rd.
6 month rentals, 6 month furnished rentals are pretty hard to come by... especially looking to rent starting Feruary 1. and for a 6 month rental, you would have to pay the agent commission on top of it. You may be best served by looking into apartment complexes in the area that you want to rent. Realtors are not going to have anything for you for 6 months, 90 days from now.
The best taht will happen is that you will be sent listings.. 1 year lease listings.
Continue your due diligence, learn about apartment complexes that rent directly to you, that may be you best bet.!
