They answer for the whole loan, not a share
A guarantor or co-signer is not responsible for half: they answer for the full balance if you stop paying, and the lender can turn to them without waiting.
Your income does not quite cover the price, or your credit is too young. A parent can back the application, as a co-signer or a guarantor.

Their income enters your ratios, their debts too, and they answer for the loan if you stop paying. We price what the backing changes and plan their exit before signing.
See what backing changesI first calculate your capacity alone, then with the relative’s income and debts, to see what the backing changes for the target price. Depending on the lender, a co-signer on title and a guarantor off title do not give the same result, and some accept only one of the two.
A bank will say yes or no according to its single policy on guarantors. I know which lenders accept a guarantor without putting them on title, which count their income in full, and which allow removing them without breaking the loan. The exit is what matters most to your parent.
Your capacity alone, the target price, and what is missing. Sometimes a gift is enough, without committing anyone.
Co-signer or guarantor, depending on what the lender accepts and what your parent is willing to commit.
Income, debts, credit for both people. The relative is reviewed as a borrower.
The moment and the condition for removing the relative from the loan, known before signing.

A guarantor or co-signer is not responsible for half: they answer for the full balance if you stop paying, and the lender can turn to them without waiting.
In their own ratios, your loan counts as if they were paying it. If they want to refinance their home or buy in the next few years, their capacity is reduced by that much.
In most files you pay nothing: I’m paid by the lender that secures your financing. What it costs, in detail
A gift and backing on the application do not solve the same problem.
A co-signer is a borrower like you and, most of the time, a co-owner on title. A guarantor is not on title; they undertake to pay if you do not. Not every lender accepts both.
Yes. The lender reviews their credit file, income, and debts like yours. A relative with heavy debts or a poor file does not help and can hurt.
Yes. Your mortgage becomes a debt in their ratios, even if they pay nothing. If they plan to refinance or buy in the next few years, they need to know before signing.
Through a new review, often at renewal, once your income or credit is enough on its own. The lender has to agree, and if the relative is on title, the notary is involved.
Often, if the problem is the down payment rather than income. A gift raises the down payment without committing the relative on the loan. If the problem is income, only backing on the application helps.
Major banks, credit unions, and specialized lenders each apply their own criteria, products, and terms. A logo does not mean that a mortgage will be offered or approved.
