1031Exchange. Adding a co borrower

[Paula Rodriguez]

I am looking to sell my rental home to buy another rental but i retired and my income is limited so i don’t qualify to the same amount of the price of the sell, I can add my daughter in law to the mortgage but then she will have to be on the tittle.

Can i add her to the tittle before the se sell and how long in advance? Can a lender requirement to get the mortgage help me to be able to use the 1031 exchange
