Lots of holes I see with this program @Arthur Banks.  

HELOCs are typically bank products, not mortgage company products, so they have a lot more leeway in how they underwrite them. i.e. they are not trying to meet some government organization's criteria, just their own.

Now that you have exhausted your Low Down Payment Options (Portfolio-Conventional and FHA) you will need to use a Standard Conventional Loan and put 20% down to get your 3rd Duplex.The sky is the limit...you could continue to buy properties and build an empire or just stop there and enjoy more free time...I have friend who quit his job and just manages his properties now.Be alert, if you time it right you might be able to get down payment assistance/grants (I got $5,000 from a local program and used it to buy my interest rate down to 3.125% which is way below typical market rates for a Duplex).

@Trent Vogelgesang call a mortgage broker who offers more than vanilla programs and can originate Freddie Mac loans.

City government, changes in taxes, the spirit of the neighborhood, trends and the whims of the next generation of buyers.

He developed a program just for that need, and that was the first time he heard a member of the public ask for it.  

@Maria Adames,Welcome to BP.while the section8 program is federal, the local jurisdictions have some slightly different (or very different) implementations.

I've actually purchased the program.  

Hello everybody,My name is Juan Hernandez and i have read a bunch of books for years and spent considerable amount of money in programs and memberships but just a couple of years ago barely decided to actually start taking action.

I have invested in trust deeds before and love the program.
