Id really question the legality of this and what Greg is stating.....
You own the community. The tenant owns their home.... Say you decide every tenant needs brick skirting , and a 12x12 deck? Why not do that as well to spiff it up?
I am far from being sure that this is absolutely the case, but id venture to say if this came to a court , you would be found wrong.
I have seen this done on condo complexes but that is an ownership in which you have an undivided interest in the common areas and things can be voted on .
Id also add i feel this is morally unfair. Often times parks have low income people. You essentially want them to incur an expense for something that you feel will result in your gain.
Greg, if I'm not mistaken, your parks are not in the USA correct?
