Because of the shortage of social housing some people will wait a very long time before they get offered a property. You could have a long wait, even if you passed the 4 homeless tests and are legally homeless.
You are entitled to two reasonable offers of accommodation. When you get an offer you'll have an opportunity to view the property. Your offer letter should explain how much you'll have to pay for the property.
You're only entitled to two reasonable offers. If you're offered a property that you don't want you'll lose one of these offers unless you can show the Housing Executive or housing association that the offer wasn't reasonable. How you challenge the decision depends on whether you've passed the 4 homelessness tests of not.
Your tenancy agreement and tenant handbook should explain whether you or the Housing Executive is responsible for repairs. Ask your local office for a copy of these documents if you can't find your copies.
