Personally, I would pay off the higher rate first. 

One of the key challenges I’m facing is understanding the financing options available to someone without Canadian residency or a local credit history.From my research, it seems that a 35% down payment is often required, with interest rates around 7.5-8.5% for non-residents.

Personally, I wouldn't open up a home that isn't in good repair, from a liability standpoint if nothing else.

thanks everyone @Edgar DuarteI would suggest you research “return on equity”.  

I personally see several issues with investing in Dubai real estate right now.

I have been to the 3-day and it is a well run event, by professional persons. 

When looking at properties in other cities, I usually start by researching market trends like price-to-rent ratios, crime rates, and growth potential.

Nothing personal.

It's great for doing research, comps, etc.
