So if anyone knows the questions that can get me to the bottom of things that would also be a bit help.Thanks all  

Bottom line, you want to ask yourself, "Where do YOU want to be when you grow up?!"

you should get your financing locked down first. you may find it next to impossible to find financing for a foreigner with those kind of down payments. and for sure heed @Ned Carey advice top of the market not the bottom look for a solid 5 to 8% return instead of 10 to 15  those are for those that live there and can stay right on top of them. 

there is a loan disclosure at the bottom of the CD that reads escrow account: $5277.03 says right next to it estimated total amount over 1 year escrowed property cost:Property taxes, homeowners insurance. mortgage insurance.

We plan to live in the upstairs unit which has 4 bedrooms and 2 bathrooms and rent out the bottom unit as it's more updated and will need fewer renovations (if any, really - it's actually quite nice)...

I always taped my bedroom door at the bottom when I would leave after going in there and exterminating :). that was the concentrated area so it was the no-go zone for a while.

It's a mixed use building with 2 commercial spaces on the bottom and 3 small apartments on top.

This probably isn't going to be your cheapest option as far as bottom line is concerned for buying all these materials but you don't have the luxury of being on the ground to find the best local deals.

Bottom can be converted back into 2 units by re-adding a door.

If it is not, then you will have residue of the material sitting on the bottom of the pipes.
