Mobile homes are (in my opinion) a grade below modulars.
Neither benefit by being moved again.
As with any home , start with the foundation. And the mechanicals and plumbing under the floor. Exposure to climate , and flora and fauna.
Maybe not a big deal for some , water quality matters to me. I have hard water here. Drinkable no problem. But no sulfur stench , and no iron staining.
Well water, Not municipal. No water treatment system.
Next the roof. Never neglect it. Any hole through a roof needs sealed. And frequently checked for integrity. Same with seams and where changes in roof creates a splice of two areas combined.
Roof material are often fragile , meaning water damages them. once damaged dry rot or mold begin the work of finishing it off.
Trailer fires are less common today. Still fires. Heat tape under under the trailer on pipes is noted as the cause too often.
Electrical systems (again my opinion) are about a ten year lifespan unless inspection proves otherwise.
After electrical , the plumbing above the floor is next. (We already checked under the floor.
Paying lot rent sucks. Money gone , bye bye. In exchange for two or three pages of rules. Don't fart sideways. Mow the lawn at x amount of inches.
We're adding sprinklers you don't want and you'll pay x mount. To make your lawn grow faster. Oh , and your portion of our increased water bill will be passed onto you too.
Property caretaker positions turn up now and then.
A younger me would get excited about some , like this one...

But anyways , an old mobile and paying lot rent was not in the cards for me.
A friend bought one needing work cheap and fixed it up to resell while he lived in it.
So he was gaining equity. Not without investment ,time,labor,and risk though.
A short term rental? Maybe. If the landlord is responsible for repairs. Sometimes renting is the option. But it's not an investment.
I know a gal in a dilapidated trailer she owns through hard earned payments, on a rental lot. I do not envy her position.
