Can't sell Dad's empty bungalow

My Dad died nearly a year ago and we are having trouble selling his sheltered bungalow. The outgoings are getting ridiculous: £120 a month to the housing association; twice the house insurance and council tax (because the property is empty) ans sundry other things like electricity for keeping low level heating on when weather is cold.

Up to now these costs have come out of a joint account that Dad set up with my brother, but that is dwindling away and I and my siblings are going to have to find our share of this money out of our current income; and goodness knows how long this will go on.

There are two almost identical properties on the same complex for sale.

Both the estate agents we have used have been useless: one didn't really advertise it properly; and the current one has shown about three people round, on one occasion leaving the lights on in there and on anther leaving the door unlocked!

I feel inclined to drop the price and take that hit - partly because I would like to close this chapter in my life and move on.

Has anyone else had this situation?
