Rustico I do go to caravans to look at homes. I agree about not being able to get a good feel for them just by looking on line.
For sellers I think that caravans are useful however I 100% will say that I have NO HARD DATA that has produced a sale from a caravan. If I have a listing that is a higher end property I will go ahead and put it on caravan. For median housing I do not feel it adds tremendous value.
