I'd go for the land, you can always build on to a house but you're stuck with your land. Ours hadn't been tended in 8 years and the unforested 5 acres was covered with 15' pine and clotted knots of blackberries. Cost 800 to get the pines dozed off, and the brambles were finally driven back after a long and bloody battle. Our weapon was a Honda Foreman pulling a Swisher rough cut mower. Thing would cut anything you could force the ATV over, I ran it over pines up to about an inch in diameter.
We took the plunge into guinea fowl in hopes they will cut down on the ticks! We bought ten little keets who were about a week old. They are pretty big now, about ready to go outside, and already very noisy! I hope to train them to come to a coop at night, I've got a plan. We'll see. I talked to my only close neighbor and he has ticks too, so he said if they end up there he's good with it. It will be interesting. They are way stupid compared to chicken chicks, I swear. They remind me of the ravenous bugblatter beast of Traal. When I move the heater plate, for instance, they still run to the old spot to hide as if it is still there to crawl under. It takes a couple of days for them to reprogram. And man, when I changed their little red plastic feeder out for a big silver metal one, they nearly starved because they were terrified of it. I'd grab them and dip their beaks, I put their old feeder beside it, I did everything I could think of. It took three days for them to start eating from it, and then they were back to devouring. They eat like meat chickens...
They crack me up though. When they get scared they run to the corner of their bin and start a guinea Coriolis effect. The ones on the outside will duck down to leg level and push into the center then pop up, forcing the others outward, then those do the same thing, and so on. This is their main survival skill. Sacrifice your sibling! Like that old joke about how I don't have to outrun a bear that's chasing us, I just have to outrun my companion.
They don't stink up the kitchen as bad as chicks did by this age, which is pretty cool. But they have learned to fly, which complicates caring for them!
