I plan to hold the property for 5 years at the very least so I'm not opposed to making up-front investments that will help my return over time and of course improve my numbers to maximize a sale price when I decide to sell it.Any suggestions would be GREATLY appreciated!

If the terms of the mortgages were refinanced into 30 year AM (amortization) the P&I (principle and interest) payments would appear much lower and hence the resulting cash flow would be much higher when they (lenders) go to calculate your cashflow for DTI or debt service coverage purposes.This also could be an issue with how you file your tax returns for all of these 15 doors or a combination of the above.Either way its really easy to fix.

The intention is to hold onto these for awhile and sell in a 12-24 month period for a return on investment.

You won't have to spend anything and the return will cover your costs.  

But don't do it if you're looking to simply earn a return on your money; you're house-hacking to make your cost to ante up to buy into the market less than the alternatives of either not playing or buying elsewhere with a higher ROI but still paying a variable rent for your own personal residence.

Most lenders would probably want a year or two of tax returns and financial statements so that you could prove the NOI.

As a result of my military lifestyle, and the places I have been stationed, northern Virginia, San Diego, Hawaii, where the returns are not as great as other areas, I have started investing remotely in areas with greater returns. 

Every LLC then needs to file a tax return and should be showing profit and loss and balance sheet separately.

Just at a glance I would sell and invest your money in higher return investments.

What is important to me though is the risk and the return, not the price point (I personally wouldn't invest in low price point properties overseas and you can find more properties with a lower price point in the US).
