One Year Rent Upfront- Grounds to over look requirements?

[Amanda Chandler]

Hi all. 

I have my second property up for rent and have a question…. Long story short, an applicant and co-applicant applied for my property and do not meet my credit score minimum (which is clearly posted twice in my ad as a minimum and non-negotiable). I denied the applicants based on low credit and  sent an adverse action. They responded asking if paying upfront would work and I said no. They are now threatening me that they’re going to sue and report me for discriminating because they “took away all the uncertainty” by paying up front. 

I don’t have to take this offer correct? I’ve had multiple parties offer this and have denied all the “upfront” offers, not just them.
