I'd like to compare the size of my current house with the one of my old house. When we compare two things, depending on what we put more emphasis on, we can organize the sentences in different ways. So I've made 3 sentences and I'd like to know if these sentences mean all the same. or Are there any differences in meaning?
The size of my current house is pretty much the same as the one of my old house.
My current house has pretty much the same size as my old house has.
The sizes of my current house and my old house are pretty much the same.
