People contact me with interest, I ask them a few questions and make sure they know this is a higher end apartment and what the rent price is and then I notify them I can't accept rental assistance programs because the apartment is priced out of HUD's "fair market value" range. Most of them lie to me about being able to afford it and schedule an appointment to walk through it. I walk through it with them and then let them know about the application process and fee they have to pay which includes a credit and background check, and these fools go through with it anyway despite me warning them I do care about the results of those reports.
The 490 credit report was just a list of delinquent everything. The person in question didn't care about anything, just racked up a bunch of debt in the form of credit cards and vehicle loans and never paid a dime on any of it. All at once. I *almost* rented to a couple with a ~660 credit score because that was the highest score I saw in like 4 months of applications. The couple I ended up renting to had a credit score of 750.
