You would ask your attorney to transfer the title over to the LLC.
As for your tax question, currently an LLC can be treated as either a partnership or a corporation. By default, it's the former. Partnership income flows through from the entity to you, so there is no entity tax there. As of now, corporations pay tax at the entity level and then when the corp distributes its after-tax profits to you, you pay tax again as an individual. This is why investors normally don't do corporations.
If you want tax advice on the future, no one can really help you there because we don't know what's going to happen. If Trump does lower the corporation tax rate but doesn't remove the double taxation effect, then it wouldn't matter either way to you. 20% tax on the corp level and then being taxed at whatever your tax bracket is would still be higher than just paying a tax on the individual level.
There is also talk of Trump adding a tax to the flow through type of income. If that is lower than the personal tax rate, then things become very interesting... But that's beyond the scope of this thread. Don't count on things happening soon, anything tax related is through Congress. Trump can't pass changes that fast even if he wanted to and if we know anything about Congress, they will take awhile.
