To address if you are crazy - yes, and no.

We bought a new home before we sold our primary residence ... and found ourselves paying off 3 home loans (one house was an investment) for over 6 months. We thought our firstprimary residence would sell quickly, and it took over 6 months. We made ends meet ... just. It was a tough time, but we sure celebrated when we sold! So keep that in mind, unless you're almost guaranteed of selling at auction or before.

And then, no. If you find the perfect house that's within your overall budget, you'd be mad to let it go if you're sure you can sell your other home.

Good luck!
