If I am also pre-qualified/approved with two other lenders, B and C, and lender A denies financing, can the seller see that I am approved with other lenders? 

Now for the Panamanian trust I would establish it using my Republic of Dominica 2nd passport (visa free travel to 70 countries). 

You are probably going to need to find a B class area to make the numbers work. 

I just helped a client purchase a duplex for $330k in a B class neighbourhood that will rent for around $2800 and cashflow around $500/month with some conservative estimates for maintenance.

And like Chris notes, if you start getting added to a dozen syndicator lists, all of whom are buying large-scale, Class B, Value-Add Multifamily deals in the suburbs of major metros, and 2-3 are projecting 30% returns, 2-3 projecting 20% return, and the remainder are in the mid-teens, I would really dig hard as to what is going into those 20-30% projections.  

Everything I own now is in Class A/B areas and I haven't had any S8 tenants apply for any of those units.  

Are there any B and C class safe neighborhoods to recommend? 

Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.So, when investing in areas they don’t really know, investors should research the different property Class submarkets.

If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.Our OPINION for the most markets (always verify each area for yourself!)

Agreed, I have some rentals in a B area and have friends with them in C areas and its night and day (talking 2-3 miles difference here in locations) in amount of applicants and quality of tenants.
