You might be better off to consider a patio villa if your plan is to rent. You can get new for around 140K and based on $$ invested vs rental income received, they seem to be the best value and provide the best ROI. Rental in the summer is really hard and you have to have an extremely low price and extra amenities to get any. What you may want to do is modify your plan a little, maximize your rent and still be able to use it some until your home sells. Jan, Feb and Mar are really easy to rent and even a patio villa will get $2500 a month for those 3 months. Use it yourself for Nov and Dec and again Apr and May. Those months are really nice there and yet you get the high rent months. Go to
www.thevillages4rent.com and see the various type homes, the months rented and the rental income and you can make an informed decision. But from my observation a patio villa rents much better that a manufactured home. Someone else may have real data and that might not be so, but it appears that way from the rental sites. And I use them as I have a home I rent.
