Many people tried finishing their basements in old homes with varying degrees of success and eventually a LOT of them end up in the state you have in your subject home.

U.S. dollar is the global currency for a reason, when a country owes another country, they pay in U.S.

Having said that while your projected earnings are great they won't be able to count towards financing now to some degree- there's not an established work history at this salary etc. as 'potential earnings' are just that, potential.With that in mind your best option might be to work with a lender that is geared for working with new physicians and apply for a 'physician's loan', which in some cases will allow you to have minimal amount in down payment and may not have the PMI cavate that usually comes with putting less than 20% down.Some of these lenders will work with very minimal down, knowing you're about to have a substantial  salary, and will 'factor' it in more than any other lender might. 

I like Vacasa because they have a global presence & do a good job, but there are many, many options here from self-management to  blended models where you handle just the bookings to full service. 

I have seen a few but most are mostly just tax-focused and just promote the overall global lifestyle rather than concentrate on acquiring international real estate itself.

Depending on what your AGI is you may already be able to do it to a degree.

The state your in  will determine the degree you are concerned.

Currently, I am also finishing a finance degree from Georgetown. 

I dropped engineering my first semester and am setting my eyes on a finance degree.

But I do see an inevitable correction to some degree.
