So, how does this all apply to house hunting and home buying?

Especially after a long home search process, when a buyer finally finds a house that could actually work -- they might get stuck in trying to determine conclusively whether good is good enough.

It's understandable...

Buying a house is an expensive and lasting decision.  You'll likely live in the home for many years to come, and the various aspects of the house will shape some of the patterns of your life, relationships and more.

So, it's important to get the right house -- and a great house -- right?

Yes, 100%. 

That said, sometimes a house is great, but is not 100% perfect, and this can leave a buyer wondering whether to go ahead and jump on the pretty-amazing-but-not-perfect house, or to keep looking for something that is an even better fit for their needs or desires.

There's no magical answer here -- it's not that you should always decide to buy a great-but-not-perfect house -- and it's not that you should always eternally wait for the perfect house.

But as you mull over that pretty great house, make sure that you are not letting your (perhaps solely theoretical) ideas of a perfect house get in the way of you buying a house that would be a great home for you.
