Why? I don't get it.

EDIT: Ah, the parent edited their comment to clarify. I see what they meant now.

I think the rationale is: You don't want to be holding an asset who's value is predicated on a very low interest rate loan. If mortgage interest rates go up by a factor of two, housing affordability will come down by a factor of two (assuming an interest only loan). Better to sell now, pocket the money, then buy back in when prices are lower.

Isn't that in essence trying to time the market?

On the other hand it is buying low and selling high. It's a fool's errand to try and sell at the exact top (or buy at the exact bottom), but if you're already up nicely you have done the hard part.

[shostack]

Sure, but you're still trying to time the market.

[hiram112]

Yes you are trying to time the market but interest rates cannot go any lower, literally.

In hindsight, it will have looked obvious.

[shostack]

Actually, they can go negative like Japan. Which I guess would push asset prices even higher?

[swsieber]

Sell while the market is hot and move somewhere else. Take up to 6 months to find the new home / job. At least, that's what I think the above implies.

In fact, if you sell and want to realize gains on your home you pretty much have to move or at least downgrade, or else you and your buyer's profits cancel each other out.
