Hi Shane, rental housing is different in Latin American countries. Charles or other members here could explain the 'why' better than me. But I haved lived in Mexico and now in Chile.
Basically you're getting the four walls the floor and the ceiling when you rent a house. In some cases the lights will not have fixtures, you will have to play junior electrician buy some then install them. I didn't have that problem in my Mexico house it had fixtures much to my relief. I only had to put in light bulbs, no big deal. But it possibly could happen in any given rental situation, I saw some there without fixtures.
In general in Chile I think you may not run into that, BUT it could happen,
it depends on the owner of the property, and how they do business. For instance, in Vina Del Mar since it's a tourist town the property owners will be a little more conversant with Norte Americano rental practices since they see so many tourists. It will be somewhat familiar to you without too many odd surprises. But in Valparaiso, not likely. They will do things that may not make sense to you.
In my apartment I have put in bathroom shelves and curtain rods & curtains in the bedroom as well other minor upgrades. It's all coming with me when I move.
My advice: Any upgrades you make, save the receipts. Before you move out try to exchange your work for free rent. In other words if you have done $175.00 worth of upgrades try to get the owner to comp you that amount of free rent before you move out. That way he/she won't have to give you any cash money in return for your work, I can almost guarantee they won't pay you cash. They
may comp you free rent. In the event they won't even compensate your work AT ALL, just take out all your upgrades and take them with you.
It's different
