Do HOA Liens and City liens in junior position get removed after auction
No, nothing is ever “removed” from county records, however, their secured interest in the property is wiped out by the foreclosure. Note that does not necessarily mean they won’t still try to collect. I’ve had problems with both HOA’s and with citys in this regard. Regardless you aren’t responsible for HOA dues incurred after the mortgage you bought was recorded and prior to your purchase of it at the courthouse, though you might have to arm wrestle them a bit.
In Florida you are joint and severally liable for HOA fees racked up before the auction.
