I agree with Shell, especially regarding difficulty finding rent! I pay $50 more each month ($600 a year!) just to have my two boys, and it's not at all size dependent.
I think it would be easier to teach a dog to be alone, especially over two years. I remember having the same thoughts when I went to college. I spent a summer crate training Soro so that, regardless of what housing situation I found myself in, I would have that option.
But I think if you are set on getting a second dog, it also would be best to do it soon so you and your dog have a year or two to adjust. I would advise STILL doing separation training with both dogs, since it's no guarantee that simply having two dogs would negate chances of vocalization or destruction when left alone.
