Yes, there are mobile home parts that allow "all ages". And, currently, there are units available in your specified price range. You don't say how far into the future; keep in mind that inventory and prices are constantly changing. In addition, there are other factors to consider when purchasing in a park, such as there are additional costs for the rent space and utililities. One more thing to be aware - the park will have their own approval process. So, you could be approved for the financing of the unit, the seller can accept your offer; but, the park can decide whether or not you can live there. I don't specialize in moible/manufactured home sales; but, you would want an agent who does. I can always refer someone that does, however.
