What is the difference between a co-borrower and guarantor?

Joel Olson • February 13, 2017

co-borrower is on the Title with the main borrower. A guarantor is not on the Title, but is responsible for the

loan. It is rare for a lender to allow a guarantor, so most require individuals to be co-borrowers. There are some

considerations on tax and estate in each situation.


When a borrower is not on title, but on the loan:


Pros:


  • You can qualify for exemption from Property Transfer Tax on another purchase if you ever buy again.
  • The main borrower may qualify for an exemption with only them on title.



Cons:


  • In the case of a Separation, there can be some more involved legal work to split the matrimonial home.
  • In the case of a death, the property does not automatically go to the other borrower, so this can create additional estate problems.
