The latest Simon Communities 'Locked out of the market' study shows an 80% increase in the number of homes available, however, the majority are in the capital.
The charity says it highlights how difficult it is for people in rural areas to get a home.
Wayne Stanley from the Simon Communities says the figures are concerning.
"[People on the payment] are going to struggle in the private rental market and that is what constantly comes out in these reports. We have seen a huge growth in the number of properties available overall, but the vast majority if that has been in the Dublin region."
