Fortunately, I've learned a lot and am now trying to put all the pieces together.Due to current situation, I've targeted Mobile Homes (have been following @JohnFedro) and straight wholesaling of traditional homes.Any advise on which to focus on?

I also went with a synthetic roofing underlayment that is supposed to be stronger than the traditional 15# felt. 

You can use it in invest and hold scenarios to carry the property until you can get traditional financing however the interest rate will eat all of your cash flow if the deal is not strong enough, and if you don't get financed in a year, you'll lose the property (Plus from what I've heard from talking to a lender, you'll need 20-30% of your own money in the deal, plus a few points).

You need about 25X annual expenses to become financially independent using traditional Wall Street style investment vehicles.  

I would pick whatever option results in the highest amount of cash for you and the smallest payment with no balloon.With the cash, you can buy foreclosures for example that may not qualify for any kind of traditional financing and it would likely give you the most amount of almost-instant equity.

Low credit score do to medical issues have kept me from going to traditional loan.

@Roy N. i will be using traditional financing through.  

If you look at the US, it has long been an issue for American manufacturers in staying competitive on the world stage when the Dollar is strong, and a constant thorn that the Chinese (allegedly) keep the Yuan artificially low.

@David PearsonA traditional mortgage is done under your own name.

I'm just an investor myself, not a traditional realtor.
