Several potential sources for foreign national lending. 

Many buildings in NYC are way below capacity because they were bought by foreign investors as a place to park cash, not as an income source.

Essentially, each property owner has two accounts, one in USD for rental income, property management transactions, and commission paid to me, now the other account is in a foreign currency and deals mostly with the rental expenses and transfers from their USD account to cover these expenses.Any suggestions would be greatly appreciated!

Sewers to me are a foreign concept as I've been fortunate to always be on city water and sewer. 

Some lenders can do foreign nationals, but most are able to lend to green cards and most visa-type holders.

Another concern I would have is that if we enter into an economic situation where tourism declines and foreigners stop buying expensive second homes there, you could get stuck with a property you can’t sell that isn’t producing much income. 

If the goal is asset protection utilize bankruptcy protected assets such as retirement accounts, homesteads, private annuities, etc; an asset protection “plan” that utilizes limited partnerships, foreign asset trusts based in Nevis or the Isle of Mann, or renounce your American citizen ship and move assets to Lichtenstein.  

Apparently, your consultant did not see the need to register your company as a Foreign Business per NC statute.

Lenders that offer loans for foreign national buyers have access to financing up to 80% in some instances. 

Have we forgotten the 2008 global financial crisis that wouldn't happen in foreign countries where properties are bought with cash and the risk of foreclosures is 0?
