Since your wife is using the 1 BHK for her profession you can ask her to pay you rent for your share so that she can claim expense and you will anyways have to show some income so both will be benefited.
You don't need to show your commercial property as income from house property as it's your business asset.
So you need to only show your 3 BHK and 1 BHK under income from house property.
Hope you find the information helpful if you do please rate it 5 and provide your valuable feedback for my improvement.
Thank you
