A paragraph is short, of course, so you aren't going to get to say very much. That doesn't mean you should not have an organizational plan and some interesting ideas. You'll first have to choose where you think a good place to relocate might be. You should probably pick someplace you know well or at least have been to so you can write with some firsthand knowledge and authority on the matter. It can be a big-picture choice, like a country, a region of the country or a state, or it can be something quite specific, like a city or even a neighborhood.
Once you've chosen your dream destination, decide on two or three reasons which make this place so appealing that one would want to pack up everything to move there. Perhaps the weather, the people, the sights, or the geography would be attractive reasons to move. Choose two or three of your strongest reasons and be prepared to expand on them for at least a sentence or two. This should be fun once you decide on that perfect relocation destination!
If you are going to write this paragraph, I would say that you need to make clear why you are picking the place that you are picking.
If I were writing this, I would start out by setting down my criteria for where I would like to relocate to. I would talk about what sort of things I would like in a place to live. Then I would move on and talk about what place I have selected. I would connect my choice up very clearly with the criteria I had set.
By doing this, your paragraph will have some structure to it and it will seem systematic rather than just kind of haphazard.
