Monopoly City Streets Housing

Just done some analysis on the rates of return from houses in the new Monopoly City Streets. It seems to me that the City Centre Cottage is the best building to build if you are not running out of space.

Building	Price (1000s)	Return (1000s)	Rate of Return
Green House	50	9	18.000%
City Centre Cottage	75	14	18.667%
Cane Top Multiplex	150	23	15.333%
The Sentinel	175	28	16.000%
High Reach Place	200	33	16.500%
Nova Tower Block	300	51	17.000%
PolyHedron Plaza	400	66	16.500%
The Grid Building	500	85	17.000%
Four Sided Fortress	600	95	15.833%
Nori Place	750	104	13.867%
Honeycomb Complex	900	123	13.667%
Blanco Bastion	1100	142	12.909%
The Photat Building	1500	180	12.000%
Cubix Quarters	2000	180	9.000%
Opaque Overlook	2800	209	7.464%
Tri-Rectangle Tower	3900	228	5.846%
Spear End Summit	5000	247	4.940%
Unbounded Megaplex	6000	266	4.433%

Update: OK, just made the discovery that the amount you make for properties has an effect on the return. It appears that the higher the value of the street the greater the return on the building. So rental returns will depend on having high quality streets. Even so, the City Centre Cottage still remains the building with the best return. I am making 60% on mine!
