It may well cause a problem if your new landlord does a credit check, however, IVAs are seen as more financially responsible than bankruptcy, so if you are asked to leave and find another property, then a perfect rent and IVA payment record should persuade the new landlord that you are a good risk. If you are with a letting agency then probably they would be able to find you another property on their books without a credit check.
Your rent will probably not rise each year by much more than inflation, so hopefully your earnings will grow likewise. Obviously if you do have to leave then you would be expected to rent a new property of similar cost.
