Q: Is a rent increase from $520 to $690 at my MHP excessive?

A: Absent rent control or some other local codes, private landlords can choose to charge whatever the market will bear for rent.

This is the disadvantage of renting.

You can also choose to move somewhere else with little to no notice.

This is the advantage of renting.

Moving a mobile home is expensive and occasionally not physically possible so you're 'locked into' a specific park if you don't site the home on your own land.

That is the 'fatal flaw' of mobile home parks.

Unfortunately, I don't know of a legal fix for that. The practical solution is to not rent in a mobile home park unless you also rent the mobile home, and can simply move your stuff out and leave when the rent gets too high. (Making this a 'detached apartment' in other words.) I'm sorry but whoever told you mobile homes were a good 'investment' was blowing smoke up your skirt. They are a depreciating asset that has more costs than benefits. Your BEST option is to sell the home as is where is and move onto either an apartment (if you simply want someone else to fuss with maintenance) or your own privately owned land/house if you're willing/able to manage your own home maintenance.

Stay away from condos or home owner association areas -- those are just 'landlords' with all the costs and none of the benefits. Either get a real 'rental' where the landlord is responsible for all maintenance and you just pay rent, or get your own place without all of those 'fees'...

I'm sure this is more of a 'long term' fix because you're not going to do this overnight, but it is the only practical solution.

Good luck.

A: Based on landlord-tenant law principles applicable to mobile home parks, the increase from $520 to $690 represents approximately a 33% increase, which is substantial but not necessarily illegal without specific rent control protections. In most states without rent control or mobile home park-specific regulations, landlords may increase rent by any amount when providing proper notice (typically 30-90 days depending on state law). However, some states do have specific mobile home park legislation that might limit increases or require justification.

Your options will depend on your specific location and applicable state laws governing mobile home parks. Many states have enacted protections specifically for mobile home park residents, recognizing the unique challenges when you own your home but rent the land beneath it. For example, some states require longer notice periods for rent increases in mobile home parks compared to standard apartments, or mandate that increases be "reasonable" or tied to specific factors like operating costs or comparable market rates.

I recommend reviewing your lease agreement first to verify there are no provisions limiting rent increases, then researching your state's mobile home park laws. You might also consider organizing with other residents who received similar increases to collectively negotiate with management, as group action can sometimes be more effective. Additionally, contacting your state's consumer protection agency, housing department, or a local tenant advocacy group could provide location-specific guidance about any applicable protections. If the increase creates significant financial hardship, you might also explore whether you qualify for any rental assistance programs, which exist in many areas specifically to help mobile home residents.
