There are two answers to this question as it depends on qualifications.
If you can qualify with both mortgage payments (Current Primary Home plus the New Home) you don’t have to sell your home.
If you plan on keeping your current home as a Rental Property, then you will want to get a rental agreement in place for your departing residence as 75% your newly received Rental Income can be used to offset your old mortgage payment helping you qualify for your new home.
If both scenarios above are not possible, then it is likely you would have to sell your current home to purchase a new primary home. Or at the very minimum to have your current home under contract with a new buyer.
