Your portion of rent depends on your income and the rent your landlord charges. Typically, voucher holders pay around 30% of their income towards rent and KH pays the rest of the rent up to the Voucher Payment Standard for which your household is eligible. If the rent your landlord charges is more than the payment standard you are responsible for the difference. You should consider the size of the unit most suitable for your household. Choosing a unit that is larger than what you need may increase your rent burden and make it difficult for you to pay your portion of the rent.
