That's really good. I paid €1200 + VAT + outlays this time last year, and was the lowest quote I could get, asking a lot of people. In fairness though, sale ended up being pretty complicated and she did way more than she was paid for.
Money is not the only thing to consider. Also think of:
-trustworthiness
-will they be going on holidays during the sale
-location - mine was 2 doors up from where I work, so so handy for signing last minute documents. I know people who went for solicitors in their local towns and had nightmares trying to get stuff posted and doing stuff after hours.
-experience, many solicitors only had experience of conveyancing during the "good times" when sales went through so fast things were looked at thoroughly.
gut feel - do they feel like someone you will be happy to do businesss with?
