Raising late fees does it help train your tenants?

[William Collins]

I am thinking that my late fee is to low. Almost every month I have about 25% of my portfolio in Connecticut get a late fee assessed. My question is if I raised my late fee of $50 to 10% of rent which would be between $75 to $150 do you think it would improve this chronic late payment. I have only had 1 eviction in 3 years, and the folks paying late do end up paying. We do proceed to immediate late fee and a pay or quit notice on the first working day past the 10th (state law in CT) . Most people are also long term and so are month to month at this point, so it would be possible to change relatively easily. What are your thoughts?
