Just secure their loan via a deed of trust or mortgage (whichever security instrument is used in your state) to the property being loaned on.

Section D1-4.1, Information Relating to Transfers of Ownership Applicable to All Mortgage LoansD1-4.1-01, Determining Whether a Transfer of Ownership Is Permitted (11/12/2014)[...]D1-4.1-02, Allowable Exemptions Due to the Type of TransferA transfer of the property [...] to [...] a limited liability company (LLC), provided that: the mortgage loan was purchased or scuritized by Fannie Mae on or after June 1, 2016, and the LLC is controlled by the original borrower or the original borrower owns a majority interest in the LLC, and if the transfer results in a permitted change of occupancy type to an investment property, such change does not violate the security instrument (for example, the 12 month occupancy requirement for a principal residence).Note: The servicer must notify the borrower that a property transferred to an LLC must be transferred back to a natural person prior to any subsequent refinance application in order to meet Fannie Mae’s Selling Guide underwriting requirements.

It has been so instrumental in my investing journey, and in my growth as a real estate agent.

@Ron Masters, The 45 day list is an instrument "in writing" between parties to the exchange. 

Pay for all those kids to learn a musical instrument. 

FHA security instruments require a borrower to establish bona fide occupancy in a home as the borrower’s principal residence within 60 days of signing the security instrument, with continued occupancy for at least one year.Source: https://www.hud.gov/sites/documents/4155-1_4_SECB....

Always use a warranty deed to avoid any issues with the tittle insurance when transferring tittle.Also, Ive recently learned Fannie Mae allows transfer of tittle to an LLC without accelerating the note...Fannie updated their servicing guide to state:Unless the previous borrower requests a release of liability, the servicer must process the following exempt transactions without reviewing or approving the terms of the transfer:· A transfer of the property to a limited liability company (LLC), provided that § the mortgage loan was purchased or securitized by Fannie Mae on or after June 1, 2016, and the LLC is controlled by the original borrower or the original borrower owns a majority interest in the LLC, and if the transfer results in a permitted change of occupancy type to an investment property, such change does not violate the security instrument (for example, the 12 month occupancy requirement for a principal residence).

The Howey test is used for franchise agreements, partnership interests, pension plans, and bank instruments...mostly.The form of the agreement and what parties call it is irrelevant, courts and regulators will look at the substance of the contract.For notes, the Supreme Court created the "family resemblance test" under Reves.

Some states even require both parties to be on title and/or on the loan unless a special instrument is signed relinquishing ownership rights by one of the parties.
