How to find homes with potential rental suites in online listings

[Phyllis E.]

How can I find out which single family homes, listed for sale online, have potential rental suites, without having to call a real estate agent? I have done key word searches on things like "in-law suite" or "in-law apartment", etc. but there are so many different terms that might be used that this method isn't very efficient.  This area has lots of finished basements , and many may already have kitchenettes and bathrooms, etc that could potentially be rented out. Are there any real estate websites that identify houses with this feature? I can't seem to find out how to easily locate this kind of property for a potential "house hack"! Thanks for any tips that would make searching easier. I am  only in the "looking " stage right now, so I don't want to bother with a realtor at this point.
