As to Laura Richard's reply I complete agree you should NOT misrepresent anything to the bank. Since most large financial institutions are federally licensed you may put yourself in federal hot water by doing so. Further understand every state has different rules and interpretations, do's and don'ts and the rules often change so you are best to consult with a real estate attorney licensed in the state of interest.
There are only 2 ways to take control of a property subject to the existing lien: overtly or covertly; everything else is details.
Overtly is to write a letter to the bank telling them you have taken title to the property and put the named owner in the public records (deed) in any manner you want. It is up to the bank to determine whether they want to foreclose or not, now or at some point in the future. Their recourse is generally described in the loan document. Ownership and security interest are not one and the same. The lender's security interest remains even though the borrower transfers ownership.
Covertly is to put into a land trust and change beneficial interest. It is trying to conceal the change of ownership. In that case I believe you should say NOTHING to the bank, simply do what you're going to do. If there is a later discussion with the bank you should be honest with answers. Transferring the title to someone else does not break the law, it triggers the right, but not the obligation, to utilize recourse agreed in a contractual agreement between a lender and a borrower. The recourse of the lender is the right to accelerate the loan and begin foreclosure proceedings to secure the collateral for the loan. Misrepresenting the situation is what can get you into legal trouble so don't do it.
Realize the Garn St. Germaine Law was for estate planning purposes and if you transfer beneficial interest within a trust outside of those purposes that law will not apply and you will have none of the protections afforded in that law. Strategically thinking, that is why people use the land trust as a "cloaking device" to hide the transfer. They hope the bank thinks the transfer was within the rules allowed by Garn St. Germaine law. Transferring beneficial interest in the trust, outside the scope allowed by Garn St. Germaine law, will be considered a violation of the due on sale clause in "conforming" residential home loans.
In Texas, with laws as they now exist, I have to believe the powers that be are fine with 3rd parties taking over houses from a distressed borrower and leaving the loan in place and are OK with that same house being sold with a wrap note. Why do I say that?
In Texas when buying a house with an existing lien state law requires one of the following:
a) report the transaction to the existing lien holder OR
b) close through a title company.
If it so important to disclose to the lien holder shouldn't that have been made a requirement and not simply one of two different alternatives?
Personally I believe the state title insurance industry lobbied for this law as they wanted to direct commerce through their own portal. This law made sure those that don't want to report the title transfer to the lender must use a title company. Which alternative do you think most choose?
"Subject to" and "wrap note" sales occur frequently in Texas with both transactions violating the due on the sale clause in the loan covenants. These transactions follow state law and parties are able to purchase title insurance, naturally with an exclusion by the insurer pertaining to the due on sale issue. If the transaction was not lawful, title companies would not be allowed to insure.
Like much else in life there is a right way and wrong way to do things. Learn the right way and seek guidance from a real estate attorney, preferably one familiar with creative real estate investing, licensed in your state. Be wary of guru's passing through your state because they may not be familiar with state laws. Lastly, be cognizant advice given on Bigger Pockets is coming from people familiar with their own state, so that advice may or may not be valid or legal in your state regardless if the author is correct pertaining to their own state. It is your responsibility to verify laws in your state.
