Reflow needs a short preheat, and an even shorter pulse of maximum

So isn't really possible at home?

eBay, China, buy yourself a surface mount workstation. Surprisingly
cheap these days.

I've already got one. But that doesn't preheat the board and re-flow
everything in one go.

You generally don't want to reflow everything in one go other than
during initial assembly (where the toaster over techniques work well
since you can do that before fitting anything temperature sensitive to
the board). So general tempering and then targeted IR or hot air is what
usually works.
