I've taken down several trees down on my lot that size.
Correct that, I've helped my neighbor take down some trees on my lot. He's done quite a few.
He basically straps on some climbing spikes, takes a strong rope and ropes himself to the highest branch in the tree. He then takes his little 14" climbing chainsaw and cuts off all the branches except the one he's hooked into about 10' at a time. After leaving basically just the trunk standing, he cuts the last bit down from the ground with a 24" bar saw.
The takedown is very controlled in this method because the branches all drop within a few feet of the trunk, the trunk itself is usually only 20' tall when it's dropped, and because there isn't any branches at the top making it topheavy, the drop direction is very predictable.
Now, I've watched him do this a number of times, and still refuse to do it myself. Better to let someone that's done it before handle it.
Ones of the stories he tells is a homeowner that decided to do the same except with a ladder. What happens when you cut a branch off with a ladder? Yep, falls into the ladder and knocks the guy with a running chainsaw off of it.
If you don't have a lot of experience and more room to drop the tree, don't do it yourself.
