the landlords “far less than $249.90,” i.e. the 10% late fee assessed; the landlords could calculate the “cost ... for any particular payment of late rent ... with reasonable certainty” and “[t]he late fee of 10 percent charged ■... is far higher than a reasonable forecast of damages flowing from a breach of the covenant to pay rent On time”; the lease is a standard form; tenants must take or leave it and cannot negotiáte the late fee provision; and the late fees are' not “valid liquidated damages clauses”1 because, again, they “are not a reasonable estimate of actual damages caused by any tenant’s breach.” These allegations were sufficient to support appellant’s unjust enrichment claim challenging the landlord’s retention of her late fee.
