Not completely, but if someone really needs to get out of a house or sell they're going to have to come up off a lil bit
Usually, people sell houses years or even decades after buying/building them, so they're 100% making money off that investment unless they've fukked up really bad.
Unless it's a brand-new house. In that case, you can be damn sure the seller is getting a solid chunk off it.
Either way, prices won't really come down and no matter when you buy yours, you're still getting generational wealth, which is the most important part of the deal.
The key to getting good deals in Real Estate is stacking as much bread and credit as possible and being quick and decisive when making a deal. You can probably get a seller to come up off some grands if you got a good offer, waiting for a bubble to burst is a fool's errand.
