welfare does have income limits but if they know your homeless n shes pregnant can help.go tothe housing dept in welfare n talk to them.be honest, tel them u have income, low income, n u just need help finding a place u cam afford.they usually give u the sec. deposit....as for sec 8, as long as your low income they help. the only bad thing is, there is usually a long waiting list that your put on.good luck, i hope this helps!!!
