for the last 14 yrs we been here they raise our lost rent 10.00 every yr, last yr they went up 20.00 now 6 months latter they want to raise it another 20.00? can they?
You need to check your state landlord tenant regulations. Every state is different.
Most likely, yes. Most parks are on month to month leases, in which landlords can raise rents to whatever they want with a one month notice. A few states or local governments may prohibit it, but generally, yes they can.
