Your marital and financial situations, or the stress which you are under, are, unfortunately, completely irrelevant. You can only get out a contract if--1) The contract has some early termination or cancellation provision, and you fully comply with it; 2) The other side (e.g. the builder or developer) breaches (or violates) the contract in a material (or important way), such as by not meeting critical deadlines, or not constructing the home the way it was indicated in the contract (e.g. building a different model or not including significant upgrades); or3) The other party committed fraud, or knowingly lied about something important to get you to sign the contract.Apart from the above, you will remain obligated to the contract.
