I'm kicking myself for 2 land deals that I missed out on. The first was 27 acres in a beautiful area of Delaware Township NJ in 1996, I offered 135k and it sold to someone else for 145k. Of course I could have found the extra money and met that deal, but I decided to only go so far... the person who got that land put a 6000 sf McMansion on it and is now bankrupt. Deal 2 was a year later, 37 acres for 120k, Franklin township, half cornfield, half swamp, but quiet, convenient location, but I was scared by a set of looney neighbors who told me that it was their land and they would kill me if I tried to run them off. They turned out to be nutjobs who were just renting the house next door and their landlord [with the sherriff] had to, you guessed it, run them off. So 3 years ago I took the plunge and bought the place I'm on now for a LOT more money. Moral: Do it now and don't have regrets, as long as you can actually afford to do it.
Financing, I think, is going to get better. There is a lot of money looking for a home, and there will be more later. I'm seeing 4.875/30yr fixed mortgage rates here and Jim Cramer [if you can stand him and his show on CNBC] yelled about 3.5% rates in a few months. By the time you work up a deal with the seller, get lawyers to do their thing, it should take a few months and you will have cheaper money.
If you can get land that will make you money, like Robert's example, all the better. Plant an orchard on that land? Xmas tree farm? Fence it and rent to an organic veggie farmer? If you can get it to pay for itself then it's like no risk at all. Of course, as soon as I can figure out how to monetize my land, I'll let you know how to do it!
Basically, if you want it, and it makes financial sense, do it. You'll be kicking yourself forever if you don't.
