Do whatever it takes to sell it now.
I was in a similar situation 2 years ago. After the property did not sell with several price markdowns, I rented it. It has since fallen further in price. (Incidentally, my mistake was taking my broker’s advice and initially pricing it too high).
The hassles of being a landlord from afar are huge. First-timers always underestimate the numerous hidden costs.
I’d suggest an immediate sweetener of $2000 to the buyer’s broker. If that doesn’t work within 10 days, then lower the price significantly. You want to make a splash on the market.
