We often think of housing discrimination as situations in which someone is denied housing because of her race, religion, sex, disability, or other protected characteristic. But there are many less blatant forms of housing discrimination that are just as actionable under the Fair Housing Act.
The family was first offered a rental, but on different terms, with the landlord asking for $100 per month more than the advertised rent. Despite the higher rent, the family accepted the offer, however they never heard back from the landlord. They'll be hearing back now, with a $20,000 settlement check from the landlord.
An important point to note is that even if the landlord had proceeded with the rental, it would have been on terms that violated the Fair Housing Act's ban on familial status discrimination.
