Take a look at your complaint and the order for the money judgement to see how its worded.

Always run full reports, credit, criminal, and eviction and set your criteria in stone. 

I'm in CA, and a tenant has filed a Fair Housing complaint against me.

Smart move will do a check for criminal records, evictions and credit report.

On June 1, we received a letter that due to numerous complaints they were politely requesting that we repaint our house.

A good place to start is the housing commission where the property is, seriously consider getting home section 8 certified, it opens up a wider pool of applicants and you don't have to accept who ever they send over but can still screen tenant applicants, if in Philly try here, a good tenant doesn't reflect to no section 8 anymore there are good and bad in many income brackets, there may be also forms for disclosures that you can print to hand out, section 8 just means and extra source of income to pay the rent, some are disabled so have lower incomes, but a steadier , more reliable income source, consider VASH section 8 which visits the home every month to monitor for tenant violations, more than a landlord could and the tenant is a veteran so their benefits tied to rental contract and they do the background/criminal checkson another note yes you can collect up to 2 months security but after first year may only hold    1 month  , so last month must be applied to last month in tenants first year, Penn considers all prepaids as security, including pet deposit etc...easier to put security in escrow account from start, banks will help you set up, and paper work easier to document, if you can build into rent amount of last month security you can actually use it, such as just charge 815 for rent instead of 750 if market will bear it for unit, less paperwork and yours to keep before last month750*12=9000 1500 security but after first year must give back 750 even with out inspecting for damage815*12=9780 800 securityafter first year adds up even betterhttp://www.phila.gov/fairhousingcommission/Pages/default.aspx
