It is done all the time and should not be a big issue.
It's the other way around that's difficult. As Brenda says, just make sure that the settlement company knows what's going on.
Also, though you didn't ask--and probably don't want to think about it--you and your boyfriend should have some formal agreement (drawn up by a lawyer) specifying what happens if the two of you decide to separate. It's just better to work things out at the beginning than to face that issue in the middle of a dissolution of a relationship.
Hope that helps.
I have found this quite common with couples who aren't married, especially when one party will be on the mortgage. They assume that love is forever and nothing will ever happen to them, so there is no need to discuss equity share, sweat equity, and eventual determination of who owns how much, how to buy the other party out, and dealing with the utter mess that will ensue if you don't have a contract between you and your boyfriend.
Don't follow your heart. Follow the statistics. They can't be challenged. It's not romantic, and it's not a pleasant conversation, but once you take care of it, you'll never have to worry about it again.
Your question is easy to solve. This issue is one many couples make the mistake of not acknowledging. Please don't be one of them.

You don't have to be married to be on the deed. If you are buying the home together, as you stated, then your name will automatically be on the deed and the mortgage. However, if you want him to buy but you want an "interest" in the property then he would have additional documents prepared at his 'signing' that will deed you onto the title (not the mortgage) after the close of escrow. It's a simple process and should be prepared for very little money. Ask your Realtor to assist you with coordinating this at your boyfriend's signing. And, by the way, CONGRATS on buying a home!
