I was moving my sims one day and I didn't know what the new house would look like (how big the rooms are, etc. Sometimes houses are expensive but small), so I just tried zooming in a house I wanted, and quickly zooming out to get a glance of a house, but it didn't work out. (I don't like to waste time going to edit town and loading to see each house.)
Well, I remembered if you shift-click on a lot, it HAS to be a lot, not a road, (with testingcheatsenabled true on) an option comes up saying "Build/Buy on this lot" or something along the lines of that, and I have never tried it. It worked! I was able to check out the house and see what was furniture like, how big the rooms are, and if it is a good deal.
I just find this really neat and I don't recall this in the guide...
Mods - feel free to move this topic because I wasn't really sure if it belongs here or not.
I also wanted to mention a reason why it is important not to change lots if you are not in edit town. If you sell or buy an object for the lot, it DOES count towards your household funds. For example, if I build/buy the park with cheats and I add a park bench, the funds would decrease by $85. This cheat is basically like when you are fixing your lots that your sims buy in live mode.
