Question about David Greene's Webinar on 7/23/20

[David Sabel]

On 7/23/20, part of David Greene's webinar includes him evaluating a property.  He mentions at one point, that the rental calculator includes an area that tells you how much cash is needed for the purchase and says something along the lines of " You'll need 40,000 dollars in cash for this investment, which includes the down payment and cash for repairs." Can someone explain to me what he meant by repairs? From my understanding the house didn't need any work, but I could be wrong.  Did he mean that the extra 20k were reserves in case the house came across unexpected repairs? I am new to the world of real estate and have begun my education only two months ago. I deeply appreciate anyone's reply. Thank you in advanced
