A good idea. The only problem is the ridiculous price of pouring concrete around here!
I would really like to get more land so that I can grow my cattle herd. Probably a silly thing to do as I can just supplement with hay to be able to maintain a few more animals. Transaction costs (brokerage fees, moving fees) to sell my place and buy a bigger will probably buy me A LOT of hay.
The only other thing that drives me nuts about my current land is that it is in a valley and parts of the pasture floods very easily - spring, heavy rains etc.
So one always has to go through the thought process of "I'll never get my money back if I do this improvement... is it worth it or should I just move"
