I think your $15-20/month is way high.

You're probably right about the 1 1/2" drain size. Washer drains are 2", but you *might* get away with it. Remove the existing 1 1/4" P-Trap and stub out a 1 1/2" PVC trap from the San TEE in the wall. From the trap inlet side run a 1 1/2" PVC standpipe about 36" off floor. If the washer hose is too big to fit, put a 2" X 1 1/2" coupling on.
If you have room for a utility tub, drain the washer into that.

If there will be an inspection (now or later)... The plumbing code calls for a 2 inch trap and a 2x1.5x2 sanitary tee. The trap arm must be at least 2 diameters (that is 4 inches) in length. The trap arm should be 6 to 18 inches above the floor and the stand pipe should be 18 to 30 inches above the trap.
