I'd talk to your property manager - having a house on the market is a PIA, an inconvenience for you having to deal with the distruption. I would be trying to negotiate a reduced rent for the period of inspections/sale at the very least. TBH I think if you have the house set up well it is easier to sell it when there are people living in it - a house that is empty can look smaller than it is. Perhaps ring the rental tribunal in your state too - I am not sure but you may be able to vacate with less notice if the house is to be sold anyway. Have they issued you with any official notices, they need to as formal notice - check bc they may be trying to have their cake and eat it too IYKWIM.
From my experience renters often have more rights than they are aware of. Good luck.
