Rent increase for section 8

[Salil Prasad]

I have a house in Newark, CA rented to section 8 tenant for nearly 2 years. When I first rented, I was asked to lower the rent even though my asking rent was $200 lower than other houses in the community (same size and plan). Last year I increased the rent by $100 but they asked tenant to pay that increase. This year again my property tax, HOA, insurance all have gone up and I need to increase the rent to make up for the difference. Even now if I check rents on craigslist and from my friends who have already rented to regular tenants, I am below market by $300-$400. Where can I pull data from to show FMV? Does printouts from craigslist count
