Moving too quickly through the process can also make a buyer doubt his decision. In a really hot market where there are more buyers than sellers, houses can get multiple offers within hours of going active. If a buyer hasn't experienced this before, he may feel like he was pushed into action faster than he was ready for. He may quickly find faults about the property that he wasn't able to consider well enough before having to submit an offer. Or he may feel he hasn't seen enough of the inventory before being pushed into a purchase by the competition. Either way, the remedy is education. The internet is a great start but there is no substitute for finding a real estate professional who can supply you with local market sales data, neighborhood information, typical purchasing scenarios and negotiation strategies. Drive the neighborhoods you think you like, see houses that may not be the perfect fit on paper, compare features to price tags. Getting context for the ultimate decision is what can make a buyer feel confident in his direction.
All of that said, sometimes a buyer will find that the house they thought was perfect is not for them. There are opportunities to terminate the contract appropriately, and your Realtor can explain your options. And sleeping on it isn't a bad idea, either.
I would love to help you with your real estate journey.
