Thanks for the advice and information, everyone. I was unaware about the lockbox or that showings must occur during business hours. That information will come in handy.
As it stands now, the property management company informed us the owner is unsure if they want to sell NOW but has not come to a final decision and will not likely do so in the near future. The spouse of the owner passed away recently so they are getting their estate affairs in order. If I decide to rent another unit from the same property management, they will just roll our deposit over into the unit so it will minimize the impact on my bank account having to come up with a new deposit.
As you can imagine, there is considerable inertia against moving right now because I want to avoid the disruption to my family until I know for certain the condo is close to being sold.
I wanted some guidance from fellow Piggers so that I can protect my family from strong arm tactics or potential deceptive practices from the owner or the management company. I don’t expect any nefarious behaviour on their part, but I just want to be informed of my rights nonetheless.
