Be sure to check out the free tools BP provides to help analyze deals you may have and also market insights.

Both screen doors upstairs do not function correctly.Plumbing problems-The garbage disposal in the kitchen was not cleaned, is smelly and the rubber is flipped outwards.The bathroom sink in the smaller bedroom does not drain correctly despite us using an entire bottle of drain cleaner on it.Common areas that are not kept clean or have garbage-There was no attempt to clear the patio of years of accumulated debris and filth.

Any recommendations for free tools to do market research?

Platforms like Zillow, Realtor.com, or even tools provided by BiggerPockets can help.
