tiggeroo is right. It all depends on the park the mobile home is in. Where I live, we have very strict rules. No fences, your deck must be nicely painted, the yard must be cut/trimmed weekly, no baby pools, swingsets, etc. They work hard to maintain a nice park.
I don't mind living in a mobile home. I have 3br/2bath, central air, a garden tub, dishwasher, white walls with beautiful wood accents, plush carpets, an island stove. (I paid WAY TOO MUCH!!!) I have a nice home in a nice community.
But down the road there is a trashy park. You can really tell that they don't enforce rules, if they even have any. It looks really bad. Junk everywhere!
If you want it short term and are getting a good deal, then it's not a bad idea. But if you want it short term and are paying a lot, you will lose money when it comes time to sell. I know I will lose when I sell, but since I'm out of a job, that won't be happening anytime soon.
BTW, I would buy a mobile home instead of rent anyday. This place is mine to do with whatever I want. I don't need permission to hang a picture, paint the walls, etc.
Good luck with your decision.
