While I agree most customers do not have contracts, there are fairly common instances where customers do have contracts.

For instance, a buy-and-hold investor who's criteria is 8% CoC return will value something differently than an investor who wants to achieve 12% CoC return.

For instance, examples on how you financed your first apartment building would be great!

Does anyone have a system that they use that, for instance, when you need to find the warranty information on a refrigerator you bought for X property 2 years ago you can find it easily?   

For instance, a Grade A building on the East Coast would be a different proposition that one in Texas (value, operations, lending, etc). 

Even some real estate professionals get confused over the difference between an addendum and an amendment.An addendum is something that is added to the purchase agreement (the contract) before it becomes officially valid (known as “ratification”).If you were performing a short sale, for instance, we would provide the buyer with a short sale addendum before we accept their offer.

Like for instance you cannot leave from there to post a notice on the door, it takes a few days correct?

Also, if you are doing tear downs and or large additions n higher end markets, you can’t use the same template each time for everything, but you can for some items (paint colors for instance).It is efficient to have name, description, item numbers, etc on a spreadsheet of items you typically buy which makes ordering materials quick and easy.

For instance, does looking for properties online for an hour fall under acquiring RE?

For instance, you could face major legal issues if you accidentally (ignorance is poor defense, especially in the Peoples Republic of Illinois) charge a tenant more than what you were charged plus the state allowed fee.
