If I find a deal on an area I would consider living when I move back I would like to be able to pull the trigger and possibly refinance into an owner-occupier loan once I move back to the US.  

I would not recommend them as their points and interest rates are so high it is extremely hard to find a deal that will work with the 0% down.

Either way it would be a grey area, selling a house with a different amount of units/bedroom/bathroom seems extreme though. its an auction site, I have seen auction sites miss the fact there was additional lots in a sale.

I am hoping this number is extremely conservative given that our contractors, inspector, and realtor walked it as well. 

Like @Pat Aboukhaled already mentioned, he’s extremely responsive and has excellent market knowledge.

Verifying last 2 years of rental history and income extremely important to find the “best of the worst”.Make sure you understand the Class of properties you are looking at and the corresponding results to expect.The City of Detroit has 183 Neighborhoods we’ve analyzed.PM us if you’d like to discuss this logical approach in greater detail!

If you start a JV in name but do not give your partners proper control and decision-making rights and the deal goes bad you open yourself up to serious consequences which can lead to SEC violations with extremely high fines.Lastly, you can offer the project up to investors who have no voting or control.  

I agree with what everyone else has said, those figures seem extremely high.

Dig into reverse mortgages before pulling the trigger on anything, specifically HECM's (FHA product).

Selling would likely mean taking on new loans at much higher rates, reducing your cash flow margin unless the new properties are stellar performers.Transaction Costs and Taxes: Selling could trigger capital gains taxes (depending on exemptions) and other selling costs, eating into your net proceeds.
