even taking the very lower end as indicative of the current market,
The lowest asking price being asked for a similar property means nothing if that property hasn't actually sold. And even if it was a situation where you know the asking price of a house that has sold recently you don't know what it actually sold for.
The thing is nobody knows right now what is the top price a property may sell for as so little is actually selling, so you may sell for the price you are hoping for, or it may be a case that even at the lowest valuation your house is priced too high to sell.
If I was selling right now my instinct would be to completely "stage" the house, even moving myself in with friends or family for a little while. I'd put an asking price on the house that was quite a bit lower than the lowest priced similar property. I would market the house as rigourously as possible, even offering a cash incentive to the agent if they find you a buyer who completes by a certain date. I would allow viewings day and night and even arrange open days at weekends.
Hopefully this would generate interest, as as slow as the market is, there are still buyers out there. I would take all offers seriously, because if that level of effort only generated 1 offer the chances are that offer is the best you are going to get. And if I had more than 1 offer I would be completely honest with the potential buyers and tell them I was going to go to sealed bids. As I think that with sealed bids from 2 or more parties you get the best indicator of what people are prepared to pay and you can be confident that you are selling your house at current market value.
That said I live in the UK where sealed bids are very common, it's possible that in Dublin buyers wouldn't be that keen on it.
Best of luck with it anyway.
