I got my letter. Their figure is well below what I believe would be a fair & honest estimated valuation. Other houses around me, albeit in better condition, have sold in the last year for around the 700k mark, the Revenue letter has mine at mid-point 375k. Decisions, decisions. From a conscience perspective I am happy to use their number, I paid a lot of stamp duty in the hey-day, I can live with a slightly low-balled valuation. I'd be more concerned with what Revenue might think of my behaviour if they came to have a look! Might talk to the neighbours, see what their plan is, we are in a terrace of 4 houses on the road.
