Thank you for all the help.

Its on a slab connected to city sewer. With 8 foot ceilings, 7.5 foot with the drop ceiling in. I plan of selling to a family either starting a family or has one already (my target buyer). The home is not set up for owner with a renter, its a single family all the way.
Although I agree a master would bring in the most money (and I would love to do it) I think that it will not give me any return if not cost more than I would receive. The more I think about it the house is in too good of a condition (hence the price I paid) to waste it making it a total rehab when it only needs to update kitchen and baths. I am also afraid of losing an upstairs bedroom.
Im thinking 2 full baths instead of 1.5 is a must though. I need to put myself back in check and leave it at a quick and easy 30k rehab in a few monthes, as this is my first flip it can get out of hand easily.
If the market shifts in the area and a Master would be profitable upstairs would be quickest and most cost effective.
