The call comes in. The offer has been accepted. Someone opens a bottle. The owner has not yet received the money.
This is a hypothetical moment, but it captures a common error in property planning. We give the offer the emotional weight of an ending and the financial weight of cash. Between those two things sit inspections, financing, legal work, settlement and disbursement. Each stage takes time. Some stages send the sale backward. A plan that needs proceeds by a particular date has to follow the whole chain.
A sale is a sequence of events
Discrete-event simulation offers a useful way to think about that chain. Instead of pushing time forward in a smooth blur, it moves from event to event: an offer is accepted, an inspection completes, a loan is approved, a title issue is resolved, settlement occurs, funds are released. Each event can have a duration and alternative outcomes. Some events do not occur at all because an earlier stage fails.
Imagine two offers for the same home. Offer A is higher but depends on the buyer obtaining financing and finishing a lengthy inspection. Offer B is lower, with fewer conditions and a shorter expected path to settlement. The seller needs usable funds for another purchase on a fixed date. If we compare only the offer amounts, A wins. If we compare possible cash available by the deadline, the answer can change. These offers and the deadline are illustrative. No universal rule favors one over the other.
Run both offers through the same calendar. In one hypothetical path, A clears inspection quickly but waits on a lender; B would have closed sooner. In another, A's lender is ready and its extra price more than compensates for the wait. A third path sends one buyer away altogether. The point is not to manufacture odds for fictional offers. It is to see how a decision about terms can be tested against a date rather than against a price alone.
The model would need to ask more than how long each stage usually takes. It should ask what happens after a delay. A buyer whose rate lock expires may renegotiate or leave. An inspection can reveal a defect and change the sale price. A failed contract returns the property to the market, sometimes with fewer weeks left and new questions from buyers. The path does not restart from a clean page.
Events can also run beside one another. A lender may review documents while the inspection is being scheduled. A title question can surface before financing is final. Adding every task's average duration end to end would exaggerate a transaction that allows parallel work; ignoring dependency between stages would make it too fast. A discrete-event model needs a calendar, a queue and rules about what must finish before the next step can begin.
The Consumer Financial Protection Bureau describes mortgage closing as a process in which the lender transfers funds to a settlement agent for delivery to the seller, while legal documents transfer ownership. The details depend on the transaction and jurisdiction. The practical point is plain: agreement, closing and available proceeds are related events, not synonyms.
