Laws like "you must live in the house for 1 year before selling" meant they just sent a relative to live there free before selling for higher price.
Like investors and companies chasing ever higher profits, there's a bunch of people that think the house they own should be worth 100000% more by the time they sell it.
Even had a gen x friend be like "Well I pay rates (council services fees) while I own the property so it should be worth more!"
Bruh, getting your rubbish taken away while you live there doesn't add value to the fucking house. Otherwise I could claim paying my electricity bill while I live there does too.
