How much security deposit

[Kenneth Garrett]

I have a number of rental properties mostly single family/duplex.  I typically charge one months rent for a security deposit.  Recently I charged two months because the person was self employed and verifying the income was a little difficult even though the credit checks and background/evictions came back ok.   I am looking to expand to multifamily/commercial.
