Great tree house tree because of its branches and it grows fast, but you should have a couple of acres to keep it away from anything else. I had ficus because of their beauty, but ended up having to murder them when the pool went in due to very invasive roots. There is supposed to be some kind of root guard thing you can plant the tree in to keep the roots from spreading, but I would really do a lot of checking before planting anything. We ended up with an Australian willow which is non-invasive, drought tolerant, etc., but it is an extremely slow grower.
However, there is very little leaf debris and you can plant under it.
