I'll chime in here as one who has been mulling this over a lot as a new landowner as well.
My conclusions have been to raise beef for my own family, and then sell a few to friends as well. Grass-fed, organic beef commands a pretty hefty price in the grocery aisle. The economics of raising my own beef are much more favorable than buying from the grocery store.
The other option, of course, is to buy a 1/4, 1/2, or whole cow from a farmer who is already raising and selling grass-fed beef. We have been doing that for a few years.
That, however, leaves you without a property tax advantage. That's where I have decided that we'll raise our own small herd of beef cattle, put a good chunk in the freezer for our family each year, and sell the rest to friends / family.
I believe we just paid $635 for a grass-fed, 1/4 angus cow from a local farmer.
Do the math for yourself, and I think you will find that if you DO want to raise beef, you most certainly can do so and still make a little money on it - or at least cover your costs while enjoying some tax savings as well. You might just have to approach the "for profit" idea from a different angle since you won't be able to raise as many on smaller acreage.
Good luck! :thumbsup:
