You can make an offer to buy a new home contingent upon your selling your old home. Too many contingencies can endanger the whole process -- as a seller, you'd be reluctant to accept a contingency neither party can really control. For a short period of time, a home equity loan is probably the more reasonable option. Bridge loans can be expensive and hard to qualify for; essentially, they are like a second mortgage. You may be able to get a home equity loan at a better interest rate.
