Pretty much this..
People fucked it up for themselves...there is alot of room to RP out being some type of house realtor. Maybe buying a plot.. putting a slight decoration to the house then promoting it like an "average" house flip..
Buying just a plot.. a plot with nothing tied to it then trying to resell with a markup is a bitch move.. exploitive and mainly just greedy.. when Gil is bountiful in game and absolutely worthless outside of it.
