loose a bedroom to add a bedroom.

I do not know what make more financial sense. I am wanting to keep as a rental but it can be a fix and flip. I just purchased a house that had an addition that doesn't flow. I am thinking on changing lay out. I think a bathroom would be a good investment because it has one small bathroom with 4 bedrooms. The little laundry room is in dining area Square footage is 1256. I believe I have 2 options: 1. Use one of the small rooms and add master bathroom/laundry room. 2. Use from the dining/kitchen area to make the master bathroom/laundry room. I hope i made sense. As i go over and over in my head and cant come up with what is best. Thank You for your help!
