In my opinion the practice of advising people to transfer properties via Quit Claim Deed to an LLC is just wrong.
It is not sexy, but the majority of asset protection issues are taken care of by having appropriate liability insurance and hiring a property manager.
Here are my reasons for not moving to an LLC
1. Your tax bill will go up. In my home state of TN the LLC has to pay a $300 a year bill to the Secretary of State plus a income tax that a privately owned LLC doesn't. (Now if the LLC is owned by family and is only used for passive income like real estate you can file and exception to the income tax, but not the $300 a year bill). Also if you don't live in TN , then you have to pay a registered agent around $100.00 You are now going to have to keep separate books and tax returns for the LLC.
2. Using a Quit Claim Deed kills your title insurance policy and opens y
ou to previous title flaws unless you do it properly through a closing agent and get new title policy for your LLC. (This is a complex scenario, but trust me it does kill it unless you use a warranty deed, but using a warranty deed means you have to pay transfer tax)
3. Insurance policies for an LLC are more expensive for many companies.
4. You can't get a loan on a property owned by an LLC unless it is non-conforming and personally guaranteed.
5. If you manage it yourself then they may sue you and the LLC. If you are negligent in your management of the property, then the lawyers may sue you anyway. To avoid this then use a management company.
Now if you own the properties free and clear or are paying cash then by all means put them in a LLC, but this is a rare exception.
