40k Cash but no proof of income. Been working abroad for past 5 years

[John Richardson]

Well I'm moving back to the USA soon and would like to buy a fourplex for around 200k with a 20% down payment.  However I have been living and working abroad for the past 5 years and have no proof of income in the USA.  I didn't have to file taxes because they were payed by the employer and I wasn't a resident in the USA anymore.  I have a Master's degree in the health field and should be able to find a job very quickly because shortage in my field so I am not very worried about lack of income.    

What can I do in my situation?  Other than working and waiting 2 years to get financing.
