What he said makes zero sense. Of course a more desirable area is going to appreciate faster. He’s acting like he should be able to trade his less desirable property for a more desirable one 1:1.
Btw those disproportional numbers can be easily real anywhere in the world even in much bigger ratios, I can confirm them from Europe - if you want to invest in properties, location is absolute top priority as we all know that. Those properties appreciate faster than average market, don't suffer much drops in crises, and of course are at most desirable locations for whatever reason.
