Before I could move in, I ended up leaving that company and moving back to my earlier employer with in six months.  

In some cases the reasoning makes sense to me, as a property owner myself: it's not a smart business practice to rent to a tenant who is only in the country under a short-term status, who does not have proof of sufficient employment, who does not have a guarantor (we'd often just call them a co-signer in the US), and with whom the landlord cannot communicate (if the tenant doesn't speak good Japanese). 

Make money at self employed business (retail store) where I work with my wife as well.

As long as productivity, employment rates, and income aren’t negatively affect home prices will continue to rise as inventory stays tight.

Yes, being self-employed or a 1099 independent contractor will require 2 years of tax returns for the lender...unless something has changed that I don't know about.

Good location for me is an area with stable employment base, steady population growth and I like houses near schools or parks.

i did some research and it looks like the uber rich already employ this strategy.Would I need to form a LLC and transfer ownership?

It was required for my AAS but I discounted it as I had been self employed at 20 and felt I knew everything.

I think the big open question is employment - lots of startups are laying people off.

We would need to know your credit profile, employment history, downpayment, loan type, etc.
