When buying or selling an apartment, it often gets down to a negotiation on price, with the agent repeatedly ringing buyer and seller, trying to get an increase in the offer or decrease in price. It is not uncommon for the agent to bully, flatter and confuse both parties to get a deal done. Research shows that in such circumstances, a person may get decision fatigue, and make a bad decision. My practice is not to make a buying or selling decision after lunch, but to sleep on it, and decide in the morning, without influence from the agent.
The more decisions you make, the worse they get to a marked degree -- you are more likely to make crucial mistakes or, put off a decision and miss an opportunity. One solution is an unbending set of investing rules, which minimise the need to make decisions. Making fewer decisions improves willpower so much that it should have a major effect on investing performance.
For the same reason, decisions made earlier in the day are much better than those made later. Rather than implying that you should hurry decisions, however, this indicates that in investing, you should get better results from a systematic process of studying an investment until you have enough evidence, then actually making the decision the next morning. The "sleep on it" principle.
In today's market, there should be no rush for a buyer to close a deal.
