EEEK! I just wrote a big check for earnest money!

Earnest money deposits show a seller that you are serious about purchasing their property.  It's probably the biggest check you'll write in your life, but it is a necessary part of the buying process.  If you're worried about having earnest money down on a property, just make sure your agent explains the process so you can be assured that your earnest money is well protected.  You'll see language in the contract that says you can lose your earnest money, but your Realtor should understand the circumstances in which that can happen and steer you away from them.

You're earnest money deposit should be in the form of certified funds.  That means a cashier's check might be the best option.  Ask your Realtor if there are other options to consider.

If you're unable to write a check for the earnest money, discuss with your Realtor the option of submitting an IOU instead.  Know that it will be a short term IOU and that you'll have to make good on it quickly.  It makes your offer a little weaker than the others that are writing a check, but it might be your only option.  Your Realtor can let you know the risks involved.
