One thing to note when getting conventional mortgages and spouses.There is a 10 limit per person for conventional financing.You can either do 10 conventional in each person's name which would be 20 mortgages for 2 people or if you do the mortgages jointly, will only allow 10 in total.My thoughts are not to own joint assets until you are both married.
