It would appear your post has brought plenty of opinions, and I'll add mine with a late pile-on. ;-) I bought a house here in Oregon in 2009, 9 acres, much of it wooded, and had never sat on a real tractor. I spent $10K on a 5 year old TYM HST 330 with FEL, box grader, and rake, with only 191 hours. At that time, TYM appeared to be an up and coming tractor company, but they floundered for years in the US and now appear to be getting their act together- this was not a result of the tractors being deficient, but a failure of marketing. It turns out that this model was also sold as a Mahindra 3510, and that became significant when it comes to parts. Since TYM was a tier 2 or 3 brand at that point, I saved perhaps 30% on the purchase cost.
One thing I strongly urge is that you get a hydrostatic transmission. You're not going to be plowing fields, you're going to be maneuvering between tall fir trees, and driving over lots of fallen debris. The last thing you want to be worrying about is clutching, shifting, etc. Avoiding slipping is enough to occupy your mind.
The second thing I lucked out on- mine came with agricultural tires- very deep treads, designed for maximum traction. I didn't think I wanted them, but in the end, they were a blessing. You don't want to be driving these over your lawn, but that doesn't appear to be a concern for your use. On the other hand, over debris-laden forested terrain, climbing slopes and steering in tight corners, they will be very beneficial vs. the smoother "industrial" tread.
The third thing is that you want is 4WD for all the reasons everyone can suggest, but especially given your terrain (which I assume is similar to mine).
Whatever brand you buy, make sure you verify that parts are readily available. You will need them at some point.
Regarding my own choice- the TYM is a very capable tractor (2005 model) and mine came with a Kubota diesel engine. Engine parts were never an issue. But TYM floundered in this pasrt of the country, not really getting much of a dealer network up and running (much better now). However, since my model was made by TYM but also sold as a Mahindra, I could easily get parts from the local Mahindra dealer right down the street, or online. And for reasons I have never understood, the identical part is sometimes less money from Mahindra (and even arrives in TYM packaging!). I have had mostly minor issues with it, but did have to open the dash to deal with a couple of electrical problems and did add an electric fuel pump (a godsend if you ever run out of fuel and need to "burp the baby").
I didn't set out to do any land clearing, but I ended up having to, and this has been really rough work (even abusive) that the tractor has tolerated well. A lot of our firs around here were dying a few years back (drought and pestilence) and while that has slowed down, it hasn't stopped. I recently skidded some 42 foot fir logs from 100 ft. trees that fell over (Vevor log tongs), and my little "compact" was able to lift one end and skid all but a few of the very largest logs, for a trip to the mill.
Assuming you end up doing any clearing, you will want a brush hog. I was given an old "beater" that took a licking, kept on ticking, and kept asking for more. You can buy one new of course, but I wouldn't. They are regularly available used online and as long as the housing is intact, it's doubtful it will give you any trouble. I finally had to pay someone to do some welding repair on mine after a few years.
I'm no expert, but I am someone who has walked in shoes similar to yours. So everything here is "use or lose" as you see fit!
You've got some great advice from everyone here, and we all wish you good luck as you step into the tractor world!
