That would make the transition from you current residence to a new one much easier.
Or else, you can sell making it contingent on finding a new residence. Buyers will take this into consideration when making an offer and deciding to commit.
Lastly, you can obtain a bridge loan. My company offers this to our clients, few brokers can offer this because they are not capitalized like we are.
The way a bridge loan works is you borrow from your equity before the sale to make the purchase on the new home. This is helpful in case you want to secure the residence and need to commit. We do consider many factors about both your sale and purchase before we'd suggest a bridge loan.
