If you put yourself in the shoes of the person answering the phone, it's not only annoying to get a call from a stranger but intrusive.

I have read all the posts about sending letters to strangers asking for money but I am not asking them to INVEST in anything.

How many walk up to a stranger and start their elevator speech?  

All while strangers are being let in her home.

Thanks for the advice @Sam Shueh- I work in healthcare so I'm no stranger to bad treatment and terrible pay.

In the end, you guys are strangers and I couldn't really care less if anyone adopts the strategy beyond what I said originally, which was that I think it's a general shame that more people don't get it.

So it’s ok for a perspective tenant to expect a landlord/home owner, tonallow a stranger into their house but not ok for a home owner to ask who they are letting inHmmm I think I will risk losing the people who are afraid of being scammed instead of risking bodily harm or allowing someone to case my home so they can come back later and steal the appliances 

.: "service snake"... lol I know a guy who's phone looses reception after he hears something like that on the other end........strange.......really strange.

And as such, gets to expect to have the home to live in, without being invaded.And, imagine what it would be like to have a horde of complete strangers (and in SF right now, any open house will be a mass infusion of strangers) walking through your home, perhaps looking in your closets, your jewelry box, you medicine cabinets, checking out your stereo, your televisions, your computers....As an owner, do you really want that liability? 

Since then I've only rented to strangers (I would never rent to a friend again) and I've used good real estate agents to find tenants and I've never had a problem since ...knock on wood.
