Thanks, Crinrict, I tried a new sim and also failed to replicate this; I repeated the steps of the sim starting at 1313 21 Chic Street furnished apartment in San Myshuno, keeping the furniture when moving to empty lot at Dashchund's Creek in Brindleton Bay, rezoning it to Tiny Home and building there, buying 2 sconces and an outdoor shower, and then moving to another tiny house that I'd built on the Streamlet Single lot in Willow Creek, money tracked okay for both moves though I'm puzzled by the value of the apartment's furniture. I know it's supposed to depreciate by 15%, except for the "art" posters that the apartment has? The test sim got hit by lightning at Dashchund's Creek, maybe that straightened him out! But more likely I need moar rams, my laptop has 8GB. Meanwhile I've started a new sim since the error and didn't keep the old saves. So, as Emily Litella would say, "Never mind!" Or at least not until the next "funny" thing happens in the game.
Not related to this but observations regarding the new replaceable windows etc. in the new pack/patch: I revisited the empty Chic Street apartment in Manage Worlds and the furniture was gone but the walls and doors etc. were still there. I often start a sim in this lot but bulldoze the interior first (didn't during the error game and test game) which removes partitions and floor surfaces but not the paint on the perimeter wall. Now bulldozing the apartment still leaves the the paint but removes the windows. Applying the "drywall" texture to the interior walls is worth $92; that was available before the patch. I can also apply drywall to the exterior perimeter for $280 now, I might remember to exploit this next time a sim moves out from there. I don't have 4 Rent so I don't know if that exploit will work in the newer apartments. I live in condos or apartments IRL and have never tried to keep the carpet or stucco when I move.
