I am not referring to PR specifically.  

Cat odor is far more problematic than a small dog, but I would check landlord references to confirm how they've maintained their last residence.

Or the listing agent includes it in the property info on their website, or shares it when a showing is scheduled.

If they have not, many landlords will give bad references and it will backfire on the tenant.

Another option if you're looking for something with higher yield than index funds, that's hands off, and will teach you a lot about real estate investing without having to do it yourself could be investing in syndications which is referred to in the book Jonathan recommended.

Do you provide references?

The section references age in many places, consistently mentioning the end of the year.

What websites do you suggest to get good information?

This is a good reference for myself and personal private lenders.

Wait so is Brazil in reference to Portuguese or Irish?
