Was it 2000 clear a year?

Or, was the 2000 gross annual receipts from the Longbourn estate? Some years the gross would be less. And his net income would have been less than 2000.

We know from Wickham, and this is probably one of the places we can trust his word and that he as the son of the former steward of Pemberley knows what he is talking about -- Pemberley was a clear 10,000 per annum. Clear meaning that was net. Again, some years maybe more but never less given the amount of land and its capability to produce.
