It is for an ocean view room, which I believe is now sold out.

You can rent a room for $800-$1000.

To make a long story short, there are a lot of potential heirs of the property as the owner of the estate had many children and subsequently many grand and great grand children. 

Has anyone used demountable walls to add rooms?

You can certainly raise your room rates $30 to be more honest in your pricing.

Ever since then, in my opinion, the level of incompetence and back room dealings that have been exposed in our city government has been pretty disappointing.

I'd like to keep my mother's room locked and still have the option of staying in that room for 2-4 weeks during the school year (while the tenant is also in the house) and for a few weeks during the summer (when the tenant lives elsewhere). 

Can you try a rent by room?

@Jackie Liu, unless there are so many screw holes that after filling them it would be better to repaint the whole room it isn't worth charging for.

Also, I've added about $250 to my monthly costs to cover utilities.Looking on Furnished Finder, I do see plenty of places in my approximate price range, so I thought my target (average of $1100/room) was competitive and reasonable.
