rent property

I own some houses in Mexico and rent them out. I keep most of the proceeds from these houses in Mexican banks. when I travel to Mexico I almost exclusively use fund from these accounts.

Do I really have to pay the USA income tax on the whole amount or just what I bring to the USA? Is there any way to exclude this income from US income tax?

If I have to include ALL the income, do I treat the property as if it were in the USA (depreciation, repairs, travel, etc)?

property renovation

When we bought this house, the back portion had already been converted into a separate unit, but it was in really, really bad shape. We spent some money fixing it up, making it suitable to rent again. (Most of which was with Home Depot cards, etc.. as we figured the rent money from the tenants would pay these off anyway). We have been providing our tenants with monthly receipts, and will be claiming the income on our taxes, I am wondering if we can deduct a portion of the renovation costs? Or if there are any other deductions we can make, having a rental unit at the back of the house.. (we also live in the house, though it is a completely separate unit all of the heat and hydro to the unit is also separate).
