The Seattle real estate market is extremely competitive for buyers. When you find the one house you fall in love with sometimes a personal letter to the seller can give you a competitive advantage. The letter not only helps endear you to a seller but it also shows them how bad you want the house. If another buyer hasn’t written a letter you may come across as wanting the house more than the next buyer and this might be what convinces a seller to choose you. All the same, if another buyer has outbid you but you submitted a heartfelt letter that touched the sellers they might come back and give you the opportunity to price match the highest offer. I see this scenario happening often.
