Hi,
We are in the same position as you, except a little ahead - house is currently for sale.
Our EA is 1% + advertising (300) + VAT (Others are up to 2% I believe)
Solicitor cost is 3000 (inc VAT) for both the selling and buying part. Other quotes I got were from 3000-3500
BER you can get for under 150. Do shop around for this one.
For buying, the builder survey depends on size of house, extent of survey etc. I had quotes from 300-600 for a detached bungalow in Meath.
Good luck.
