Update: This ended with previous owner/tenants breaking in and me still happy.
I changed locks but left all personal belongings in unit as I decided what to do with them/how to get them back to prior owner/tenants. Multiple attorneys (Matt Leider included) all advised the belongings are considered abandoned (auction only) if prior tenants/owners are missing but personal property still there. One even told me that I could invite neighbors over to help themselves to make my job of removing stuff easier. A couple of them said that a writ from sheriff was not required but was the preferred advice. I did not want to simply discard someone's personal stuff. There were men's watches there probably totaling 10k or more in value, family photos, etc.
They gingerly broke in twice through a window without breaking glass. After the 1st break-in, the HOA told me to make a police report which I decided not to. The last time they finished getting what they wanted and leaving what they didn't. They even left laundry keys on counter. Didn't remove appliances, vandalize or anything they shouldn't have done (exception of breaking in). Even left a new appliance that wasn't installed, still in box.
A satisfactory end.
