Not sure what it's called but pretty sure it's one of those places were all homes are a replica of one another. Basically corporations buy plots of lands and then put on 100 or so of the same houses to sell / rent them out at a profit.
Wasn't sure about this but as she just said they're manufactured / mobile ones. So that would be called a trailer park in the USA I believe.
Basically companies buy land, drop 100 premade homes on them and then upsell that or rent it out to people for a profit. Like blackrock etc does...
