You just need a buyer that can close... hard money shouldn’t be discounted, private money, even conventional financing.

Keeps you set up with a conventional first mortgage with no Private mortgage insurance.

Wait a year until I meet the owner-occupied requirement and then get a conventional loan for another owner-occupied fourplex with 5% down. 2.

The thing is, i was born outside USA and i never been there, so i dont have any score or tax history and many lenders told me that no normal bank would accept me even if it is for an investment MFH so i spoke with several professionals.Most of them told me to pay taxes as a 1099 two years back and start building a score somehow with credit cards and so on, because no lenders or banks cares about taxes of expats cause they dont consider them "real" if they are under the 100K annual cap, that most people lie about that kind of info, sounds really stupid to me but i dont know really.Realtors told me i should buy a first house with some bad credit, near 10% interest, 40% Downpayment for 15 years (something not really nice) and with that i could start to build a record and obtain after a few months a conventional 4% interest, 25% Downpayment and 30 years (normal mortgage) I would like if anyone could give me any kind of advice on this situation, i just want to start RE portfolio in the states and i think that with the chance to have good credit, its a joke to go full cash when buying !

@Greg Gerken On an FHA 203k (and conventional rehab loans), In order to GC the project yourself, there are a few things to consider. 

Are they better than FHA or conventional loans?

You are generally looking for a conventional cash-out refinance at 75% LTV.

It'd be iffy if the home could qualify for a conventional mortgage considering all the rehab it needs, so I don't think a regular mortgage is in the question.

I would also reach out to a lender or two for conventional debt to see how this compares to the credit union.

Commercial financing is different from conventional residential financing, so you aren't comparing apples to apples.
