Not learning the most basic of sales techniques, like answering a question with a question will cost you time, deals, and money. Saying not to do those type of things is like saying "I won't learn to negotiate, I'd rather wing it"... which is what you're doing if you don't learn certain cause-effect and planned responses.
Asking the right questions is the key to knowing how to reply...
From the information provided in the 1st post, she was losing control of the conversation, which caused her to lose deals... and money. The seller was asking all of the questions, she was answering them, and getting nowhere. (and losing potential deals)
A little sales training makes all the difference in the world... and without it, a car salesman (or investor) will either fail and leave the business, or do a lot less deals. We're all in the sales business, whether we admit it or not.
I'm NOT saying to lie, hustle anyone, or "take" someone for anything... but learning the most basic freshman rules of sales will accelerate your learning curve greatly, and answering, then asking another question is one of the 1st things a salesperson is taught in sales 101.
It can be the difference between getting 3 contracts signed of 10 house visits, (or phone calls) and 7.
Being up front and laying all your cards on the table is great, but knowing what to do (and how to do it) when being up-front doesn't work is also important. In time, it becomes second nature.
Some people are so motivated to sell that you can say everything wrong and still get the deal, but you also have to know how to deal with the "difficult" or skeptical seller to maximize time and profits. Most investors don't want to settle for only the "easy" ones.
Again, I'm NOT saying to be rude, lie, scam, or BS anyone, but you'll get a lot further knowing persuasive speaking techniques than not.
