Magic Book Where Female MC is someone who buys places at auctions and has to clean them.

She is a self taught mage and buys house/apartments at auctions and has to clean them. Think buying storage units. I think the plot is something she finds in an apartment lead her to discovering some people are going to kill an almost extinct group of animals. This is also a series and later we learn her adopted dad is a dragon but she ran away from his strict rule and that’s why she’s kind of poor. Also I think she turns out to be a wild witch at some point cause her magic doesn’t work with the current magic system. Read this on kindle a couple years back.
