Local pickup for speakers - should I let the buyer in the house or use the the garage?

I have to correct myself! I was robbed on another occasion. I had a pair of cheaper speakers for sale. A single YOUNG guy ( I will not mention his nationality or this post will get flagged). He listened for 30 minutes and then talked for an hour or more. No Sale. I went back to work. He returned to my house and jimmied a window and took the speakers and a few other things. When I got home, it took me 30 minutes to realize that I was robbed! (too much stuff!). I managed to track him down being it was pre HIPPA days. The police got my stuff back. I had the ad in my local paper BTW  

In my first response I forgot to mention I thoroughly research people I don’t know on Google before doing business with them. You can get lots of info on a person and also call the local PD for background if you’re still worried.

Fool me once is once to many.

Garage pick up.

I've sold a lot of equipment from my home.

If it's through a local media like craigslist  it's always from the garage..

If it's from Audiogon / USAM , it's from the listening room. I always have the person give me a call to discuss before the meeting. 

For the record, this hobby seems to have a fair amount of introverts ,

I remember may years ago taking my eight year old daughter with me to buy an amplifier from a local seller, (she had been with me for a handful of transactions since her mom worked nights. weekends), as we get in the car to leave, she asked me  a simple question about the upcoming transaction "are they weird"

For anything less-expensive, like cheaper receivers, CD players, TVs, etc. I just have the unit set up in my garage and playing when they arrive so they can see it works.  People buying that level of gear aren't super picky audiophiles like many on this board.  Ex: I sold a guy a $100 Marantz surround receiver last week for a system he's putting together in his bedroom.  He asked if I had anything else for sale and I mentioned a Sonus Faber center channel speaker.  He had never even heard of Sonus Faber before.  Marantz, Polk, Sony, Pioneer, sure.  SF?  Nope.

For anything nicer, usually those people would like to discuss everything on the phone anyway, which is fine.  You should be able to qualify them pretty quickly at that point so it's no big deal.  They're usually going to ask very specific questions such as "about how many hours are on the current tubes in the amp," or "has the unit ever been serviced?"  Those are very specific questions that people in this sphere know about and would ask.  Whereas most dumbasses are going to ask stuff like "how loud does it go" or "how many watts are those speakers?"  Ugh.  Those people are probably not your buyer/ customer.

I have had people drive from adjacent states to buy gear and every transaction went very well, (after some texts and a phone call).  For that gear, those buyers would appreciate a better experience, like I would, in buying something of that caliber.  So I show the piece set up and working in my home office system.  At that point rarely does meeting result in a "no-sale."
