The word “approximately” matters at this price. I would ask for the floor-area verification and energy information before deciding whether to view. “Average-to-good” is also broad: does that mean mainly cosmetic work, or are there maintenance items already identified?
I’d push back on vacancy being the main explanation without more detail. It could instead reflect seller motivation, presentation, condition, or pricing. Financing may also affect the gap between an accepted offer and a completed sale.
For the next few weeks, keep the same cohort and note...
