It depends on what you mean by "break even." If you're trying to end up where you started financially before you started the process of buying the house then you're asking a lot. You're essentially asking to get free housing for the 1 1/2 years.
The only "income" you have from this process is the additional equity in the house (the principal reduction of your mortgage). Everything else is an expense:
- all of the fees you incurred buying the house
- all fees that you will incur selling the house (including a 6% commission possibly, plus closing cost concessions to the buyer in the neighborhood of 3%, which are common these days)
- all interest, taxes, and insurance
- all improvements
- all utilities
Add up all of those expenses, and subtract the increase in equity, and that's the difference in your sales prices and your purchase price. It's a big difference. You may have been able to pull this off 6-7 years ago, but probably not now.
A more realistic goal is to at least lose only what it would have cost you to rent a comparable house. (That's essentially what you're doing anyway.)
