Cork Simon Community says people are spending everything they have to try and keep a roof over their head.
This follows the latest Locked Out of the Market report which showed no properties were available to rent under the HAP scheme in June.
The organisation says more and more people are being pushed into homelessness - as the private rental sector isn't fit for purpose.
Speaking to RedFM news, Paul Sheehan from Cork Simon says they're meeting those struggling at their soup runs:
"We're meeting, quite a lot of them at our soup run every night. They have nothing left after the rent and the utility bills are paid, and they have the can't afford food. And quite often, we're going to see them, knocking on our door in the next three or four months looking for an emergency bed".
