so i closed on my first duplex

[Tereal Wilsonn]

So I closed on my first duplex in oak park Michigan a suburb of Detroit . so I just became a landlord and a home owner , I have alot of questions floating around so I tthought  is start here. 

So I have to admit some mistakes I've made already , I didn't get estopple letters  before inheritng the tenants ,however in in the process of getting them done as the new owner, 

What should be my method for collecting rents ? I setup an account for tenants to deposit the rent checks , please advise if there is a better method. 

What's the best way to communicate with my tenants ?

What other paperwork should I have on file for my tenants , Should d I have a copy of their renters insurance policy. 

Just trying to understand what exactly what I need to be successful , please recommend and helpful books I've been reading" first time landard " by Janet portman 

All help is great
