Would you add a 4th bedroom

[Dennis Robinson]

i currently have a rental that is 1,600 sq feet,  3 bed, 2 bath.  I am considering adding a 4th bedroom in the place of a front living room.  The front living room was a permitted addition before I purchased and is approx 300 sq feet.  There is a smaller family room toward the back of the house that is original.  I understand I can probably get an extra couple hundred dollars a month if I add it, but will it be worth the cost?  Would the large front room possibly keep tenants there longer if left the way it is?  Maybe create a master suite? It's a middle (to lower) income area in southern California.
