My landlord gave us until the 24th to pay and we are about $600 short (Jax,FL)

Tatiana, your family may be a candidate for the Emergency Assistance Program through the Duval County Behavioral and Human Services Division. I cannot say if they will be able to grant you the $600 that you are looking for. The actual outcome will depend on your eligibility for rent aid and whether it will be feasible for your family to continue making that rent payment based on current income. Your social worker will be able to provide referrals also if there are additional needs following your appointment.
