I am selling my deceased Father's empty house. I have spoken to two estate agents - one recommends an open house to get people through the door and one says don't bother because in the current climate nobody will come. I suspect he may not want to do it because of the extra work involved but genuinely don't know if it's likely to result in a quicker sale. I'm not in any huge hurry to sell but don't want it hanging around for a year. What should I do?
