Well, we have had countless discussion on here about the cost of repatriation to the US, and housing is always the major stumbling block for many.
Now, the recent spike, and it is a spike, hasn't made that dynamic any easier. No as with all housing booms, prices at some point will ease but maybe back down to where it was, which was still too high for many.
When we sold our BKK condos in 2017 we re-invested in rental properties here, and we're seen an almost 30% appreciation.
Now is that sustainable, probably not, but what it's also done is drive up rental prices, which if you are in a location with limited availability probably won't drop to the same extent as the property equity, when the correction comes.
So yeah, to @Jingthing point it doesn't help if someone wants to do the simplest relocation back home.
So as I have always said to folks. If you have a house in your home country, and that applies not only to the US, don't sell it.
Keep it, rent it out if you must but its your ultimate bolthole if push comes to shove
