After that I plan to make a career in the financial sector in a major Florida city such as Jacksonville, Orlando, Tampa, or Miami. 

Are you only looking for turnkey or are you looking for some major/minor rehabs to add to your rental portfolio? 

Your VA loan will allow you to finance the entire purchase of the property with no money down, and will get you a lower rate than if you went with another loan product.

I'm not a foreigner national, but know of a product that is mainly for residential properties. maybe 2-4. interest rates are higher and the down payment is higher too.

Look at major employers, economic trends, etc. 

Then refinance after 6 months to pay off the majority of the HELOC. 

The mortgage industry is due for a major contraction at this point.

All tile floors setup to be very low maintenance. old bIIldIng but most of the major work/ repairs have been done.Building is very near a redeveloping area, in 5-10 years should be a much nicer area of downtown, but they will still be low income apts.Its unique in the fact that it is surrounded by new buildings so it is its own ecosystem, if that makes sense.. problem is that ubless you dropped serious money into it its always going to just be what it is. low income. very small spaces, would have to empty entire building drop 100s of thousands on it and re rent with new image..

@Elia S.You are going to have a really hard time finding any banks or commercial lenders doing a non-recourse loan product on a loan amount that small.

So the property address should be the same as the mailing address for an overwhelming majority of them.
