I am doing a loan for a computer programmer.  I am a reasonably "technical" guy but nothing like him.  I got through HTML 3.0 before I gave up on webpage development and he&39;s waaaaaaay beyond that. But the conversation drifted around to the topic of the "Un-Do" feature of computer programs like Word, Excel, and many others.

If you make a mistake in typing or formatting, you can hit a little button with an arrow on it or click on EDIT – UN-DO LAST ACTION, or select Ctrl+Z and it will return you back to some point before you made the mistake.  This can be a lifesaver if you accidentally delete and entire document before you&39;ve saved it. 

Unlike a computer program, buying a home and financing it do not have Un-Do buttons.  If you make a mistake, you live with it. Un-doing a purchase you shouldn&39;t have made means selling a property, which will cost you many thousands of dollars in real estate commissions. And perhaps there&39;s a problem with the property and maybe you can&39;t sell it for what you paid for it.

Refinancing a property isn&39;t that expensive, but it still costs thousands of dollars to get the right mortgage. There&39;s no reason you can&39;t get the right one the first time.

This emphasizes the value of getting good advice from your real estate agent and your mortgage loan officer. Truthfully, many of them do not care if you make a mistake just as long as they collect their commission!  So choose your agents carefully and make sure that they will help you keep from wishing there was an Un-Do button to push.
