Real estate agent best practice 
This question is a bit off-topic, might be better moved to another SE site. But I'll answer anyway: Sounds like the problem is that your wife is potentially being taken advantage of by people who may not really be prospects. Keep in mind no one can take advantage of you without your permission. There are also some things you and she can do to reduce the amount of wasted time while minimizing the risk of giving up on a potential sale. Qualify your leads: make sure these potential clients are really, truly potential customers. Ask whatever questions you have to ask in order to qualify them as real house hunters. It doesn't have to be binary: you can have hot leads ready to buy now, and lukewarm leads who may not buy for 12 months or more. Treat each one accordingly. Set limits: a lukewarm lead is not allowed to call you 20 times a day. Answer their calls just once per day. By answering the phone every time they call you are training them to call as often as they like! If you only return calls once per day they'll quickly learn to save their questions up and ask them all at once. Showing 10 houses sounds a bit silly. How can you remember any details after seeing 10 houses? By asking more questions and learning more about what your clients want in a house, you can reduce the footwork. Me, I'd flat out limit it to three houses per outing, and I wouldn't even hesitate to tell the client why. I think all these things will come in time. Like any new venture, she needs some experience to learn how to maximize her efficiency and effectiveness. Keep in mind it's better to have the phone ringing too much than not at all!
