Multitool is more useful on the removal/prep than the building. The Fein is an effective sander as well though.
Not to put you off buying one, they are essential for a professional but they pay for themselves over a longer time by getting problem jobs done quickly.
Unless you have very tough (i.e. expensive) blades they will eat blades if you end up chewing through a hardened screw in a piece of wood. Blades consumption can end up being expensive if you're not careful.
Many times though, even if it costs in time and blades, if there's a thing that needs cutting in a difficult spot things might well have been much worse without one. I do use mine for cutting floorboards, a depth stop is handy in this case. Just in case a plumber has notched the central heating pipes.
Also handy for removing the grout between tiles if you need to lift a single tile.
