The problem normally that comes to mind with this strategy is two fold: 1) You have to take title to the property (even if only for a second) so there are double transfer taxes, double closing costs, etc., to pay...., and 2) the new buyer may have trouble getting a loan because now you have a title seasoning problem (most banks only wish to give loans secured by properties that have been held by the seller for 12 months or longer).

Once you have a system down, it's easier to transfer that system to multi-families.  

Thanks Wayne,  what if I buy it under owner occupied and transfer it a year or so later to an LLC?

Also, you cannot get a 30 year fix mortgage in an LLC unless you buy the property in your personal name and transfer into a LLC.  

I still don't know what to call the alternative, the one where title is transferred.

Due to nothing I did, the home has been transferred into a relatives name.

I don't remember the transfer being too costly (we owned 1 personally and transferred it to the corporation), however, costly is a relative term.  

If not I've heard about transferring the deed to the LLC after it has "seasoned" but this can also cause the lender to call the loan, which of course would not be great. 

Depending on the lease you used your document may have a transfer of ownership clause or something similar which requires your consent.If you do not have a personal guarantee or some sort of material change or adverse change provision, I am not sure what recourse you may have with the sale of the business operation.

I even do my own deed transfers, but you definitely need an attorney.
