Changing to fit the market

[Michael Porter]

My market is flooded with rentals now between trailers, SFR's , and small multi-family. Some of this may be due to people unable to sell their SFR's so they just rent them out. I am very familar with multi-family i grew up learning how to manage multi-family property. I am seeing vacancy rates climb so now i feel like i need to change my direction in my current market. Has anybody been through this kind of market that can give me some insight?
