This topic has been discussed a few times before, it is never a good idea to have joint names on house, people who joint names do so because that's the only way they could afford the loan. Since you can apply the loan on your own, there's no need for joint name. If you want to give assurance to your wife, create a separate agreement or something.
Bear in mind if your house is on joint name and something happened to your wife (touch wood), her half-ownership might fall to her parent or siblings, and you might have a hard time trying to sell in the future
