We're seriously considering buying a mobile home. It sounds like a joke, but it makes tremendous economic sense.
It's $85k. We'd offer $80 with 30% down ($24k), for a total mortgage of $56k. It's in a co-op, which means no space rent, but which also means the interest rate on the mortgage would be ridiculous (as much as 12%) and the loan terms quite short (10 years or less), BUT that interest is tax-deductible. If we had a 10-year mortgage at 12%, our monthly payments would be $803. If we got the more common 7-year mortgage, our payments would be $988. The HOA dues are $270 a month. Property tax is around $100 a year. So worst case, our monthly costs just to have a roof over our heads would be $1266 a month, with an annual interest deduction of about $6500. Compare that to our current rent of $2k per month, with no tax benefits at all. In seven years it will be paid off and our monthly costs will only be the HOA dues. The co-op expires in 2025, after which it's anybody's guess what will happen to the park, but by 2025 I hope I don't care.
There isn't much dirt for vegetables, but I could have an herb garden. An elderly lady in my ward has offered her backyard for vegetable gardening, which would also get her free veggies. I might be able to find somebody to host a chicken flock if we split the cost of feed with them. There are lots of solutions.
There are drawbacks as well. No garage. No real yard. My own prejudices about what kind of people live in mobile home parks. We stopped one couple walking through the park and asked them how they liked living there, and they couldn't say enough good about it. Renting out your unit is not permitted by the HOA, although the realtor admitted that there are probably a few rule-breakers in the park.
