I'm sorry to hear that you're having such difficulty. This was one of the topics covered at our Board of Realtors general membership meeting this morning. The Connecticut Association of Realtors legal counsel was the guest speaker, so this is very fresh in my mind. It is against the law for a landlord to deny you as a tenant based on holding a Section 8 voucher alone. If there are other reasons, such as poor credit, poor references, frequent late rent payments, pets, smoking, well, then they have a valid reason for denying your application, but you cannot be denied just because you are a section 8 tenant.. You should consult with your real estate agent .
I can understand your frustration in trying to find a suitable rental home with your section 8 status. Do keep in mind that you have a lot of competition as the rental market has been very active so the landlords have a choice on who they can select as tenants.
If you have signed an exclusive representation agreement with your current agent then it would be a breach of that agreement if you work with another agent.
Have you looked on Craigslist.com? Many landlords advertise their rental properties on that site. But...do be cautious as there are numerous scammers out there attempting to gain your persoanl information or money. Do verify if the landlord is indeed the true owner or property manager before giving any personal information or deposit with them.
Good luck to you!
