If they do handle an unrepresented buyer, no other agent involved, the listing agent will likely have the extra charge in their listing agreement already to cover the additional work and risk.

If you're applying for a Conventional/FHA/VA/ or USDA loan, then they will do a "global cash flow" where they take into account your PITI (Principal + Interest + Taxes + Insurance (hazard and flood) on all properties (second mortgages included), HOA payments, car payments, student loan payments, credit card payments, and installment loan payments in the numerator and your gross income in the denominator.

I'd like to reach my passive income goals here in the states first before making the leap.

Here is a quick tip lenders usually lend you up to half your income.

Paying rent will force you to maintain a personal budget, it will ensure your property produces the income necessary to operate the property, it creates a savings for you as a landlord so you can prepare for the next investment, and it shows how the property performs as an investment in case you have to sell.You need two accounts: checking and savings.

Use liquid assets to assist in meeting full doc debt-to-income (DTI) ratio requirements. - Cross Collateralization.

Additionally, Wilkes-Barre Property Management is well-reviewed and known for their professionalism and expertise in the local market.

Additionally, I am looking for a real estate investment opportunity, ideally something that produces decent cash flow. 

You can look at a conventional cash out refinance which uses your employment and income as well as DTI to qualify you...or if that is an issue, then I'd suggest a DSCR loan.
