Estate Agents Valuations

[Ric.ror]

if an estate agent values a house at £99k what would be a reasonable first offer

[AB Editor]

I would compare it to houses that have been sold nearby recently and see the difference.

If the one you're looking at doesn't have a [insert desirable house thing here] but one recently sold does, you might want to reduce it by the value of [desirable house thing]

This will tell you recent house prices:
