It will be similar to the dungeon exploration, with a view of the house room on the left, and some stats on the right:

currently I'm considering this mechanic: there's an alarm/noise level, and even if Joanne will use her noise reducing spells, triggering traps or fighting will still cause some noise. So every time the alarm value increases, if reaches the maximum you'll be forced to abort the mission and retreat.
I thought that could be possible to just "Wait" (and hide using Joanne's invisibility) and lower the alarm value, but at the cost of some time.
It's a pretty standard mechanic in stealth games, but since basically everyone hated the "days to next plot mission" feature of SOTW (except the few enthusiast people in forums
I can just remove the wait button and only have the alarm level, or even remove that thing too, and just have exploration+battles like in the dungeons. For some early houses probably wouldn't even make sense, since there will be only a few rooms so will be hard to increase the alarm
Lastly remember: the potential targets are unlimited (randomly generated). So even if you're forced to escape, it's not like you are stuck. I can also imagine people could save at beginning of the mission. Because of this I don't think should be a major issue, but never hurt to ask!
