The books have already been written, they are the Fannie Mae Mortgage Underwriting Requirements, Freddie Mac, FHA, VA and USDA are pretty much the same with spin off requirements for unique programs.

All contracts, options, or other devices not based upon a substantial consideration, or that are otherwise employed to permit an unlicensed person to sell, lease, or let real estate, the beneficial title to which has not, in good faith, passed to such party for a substantial consideration, are hereby declared void and ineffective in all cases, suits, or proceedings had or taken under this chapter; however, this section shall not apply to irrevocable gifts, to unconditional contracts to purchase, or to options based upon a substantial consideration actually paid and not subject to any agreements to return or right of return reserved.

My banker let me transfer my property out of my LLC into my personal name to do a residential Freddie Mac mortgage and then transfer it back to my LLC after closing.  

If you're purchasing the property from a government entity (Fannie Mae, Freddie Mac, HUD), or if you're purchasing the property as a short sale requiring bank approval, there may be restrictions imposed on your resale. 

I know Fannie Mae/ Freddie Mac will issue up to 4 loans at a time for newbies, but with no money down they are virtually impossible to get a hold of for investors.

See below statement (also in the last para in the link)"Loan investors, including Fannie Mae and Freddie Mac, often create their own PMI cancellation guidelines that may include PMI cancellation provisions beyond what the HPA provides.

You just figure out revenue split with the property owner and have to keep the devices filled and serviced.

Apparently, Fannie Mae and Freddie Mac get very confused with properties that have traditional homes and mobile homes on them together.As such, I've been pointed to several portfolio lenders.

But as long as you CLAIM your income, it will count towards a traditional loan that will need income on your tax returns to qualify you.Generally speaking there are 2 main types of loans for investors: “Conventional” and “Portfolio”Conventional - I'll define these as loans that come from Fannie Mae and Freddie Mac (if you recognize those names).

Can you provide me the name of the device?
