I can comment on this because I have done the exact same thing you are contemplating, in California. There are pros and cons to this. I can tell you one thing - it's a simple process to do it yourself and you don't need a lawyer. On the other hand, when my parents did our transfer, they got the property description wrong, and it had to be unwound. At that time, I paid a nominal fee for help from a guy who did title work for a living, at about 1/10th the price of a lawyer. You could also go with a title company or a paralegal, but you would likely have to pay more.
A possible pro is you keep the property at the purchase price value (plus 2% a year) for property tax purposes. I say possible because I am not totally sure this will work. I know the El Dorado County tax assessor keeps an eagle eye on the obituaries. My parents home was in their trust. When my step-father passed, my mother soon got a letter demanding she re-title the house, removing him as beneficiary. When she passed, I got a letter demanding the same. The house remained in the trust, but the beneficiaries were changed to me and my sisters. If I ended up with the property, as provided for in the trust, property taxes on 2/3rds of it would have been excluded from the Prop 13 exemption since transfers between siblings aren't exempt. If I were you I would see a tax expert, or an estate attorney to make sure under the new Prop 19 you don't get hit anyway with part or most of the property tax increase.
One huge, and I mean huge con is the income tax disadvantage you will face if your parents transfer ownership before passing. If your parents "gift" you the property (not considering gift tax here), your tax basis becomes their depreciated tax basis. So, if they bought an 8 unit apartment building in 1980 for $400k (current value $4M), and subsequently depreciated it down to the land value of $100k (plus undeducted capital expenses), your tax basis would be $100k. Instead, if you inherited it when they passed, your tax basis would be the value at their passing, $4M. So, you would not only lose the ability to depreciate the property on your annual income taxes, you would pick up a major federal capital gains tax liability. Add to that another 13% for Gavin Newsome (as I understand it, Cali taxes capital gains at ordinary rates) and it gets costly.
