@Jason Albasha, @Alejandro Calixto, @John Warren it definitely seems like move in fees might increase your cashflow. However personally, I like giving a people a chance to get their money back.
The additional security deposit (double the normal), I would do during the winter months when demand shrinks. Before COVID I gave some people who were borderline a chance. It mostly worked out, but I had an instance in which someone did more damage than a normal security deposit would cover. The additional security deposit prevented me from losing money. But those days are long gone, I won't take the additional risk on tenants due to the new laws and the moratoriums put in place. I'll see how move in fees work out my building in Chicago. I'm in the class C market and even my best tenants who pay on time, are very clean, somehow still manage to break stuff.
But, I agree that tenant screening will eliminate the need for full security deposits, especially as you move out of class C rental market.
