Ryan - unfortunately, the way the realtors work here is not the same as in the US. In the US, a realtor has access to all the properties on the market and can show you anything (maybe with the exception of for rent by owner kinda stuff). Here, all the realty companies have their own inventory, so you end up having to look with several realty companies to find out what is available. To make things harder, people are sometimes reluctant to put signs out advertising that their property is for rent/sale as they feel that it makes the property a target for robbery, etc. Anyway, you can try some of the major real estate companies pyg.cl, elbarrio.cl, remax.cl, etc. The other option is to hit the streets and ask in the buildings you like (asking concierges) what is available for rent in the buildings.
Furnished apartments also aren't very common - just FYI. You can look at "apart hotels" but what you will get will be expensive and small (in our analysis, not worth it).
The other thing you need to be aware of is that realtors fees are different than in the US. If you rent an apartment that a realtor has shown you, you will pay them 1/2 the rent of the property as their fee (the seller also pays half, so the realtor ends up getting one month's rent for their effort - which effort is usually minimal in our experience!). Most Americans are shocked when they learn this, so plan it in your budget.
What is your price range? We have been looking at some furnished apartments ourselves (we live in Las Condes) and I can give you an idea of what you are going to be able to get. Also, where exactly are you going to be working, do you want to be within walking distance, will you get paid in dollars or pesos, do you plan on buying a car/driving. I know of a smaller apartment that is furnished in the area that might be up your alley - it was too small for us.
