So, let's say that your house is listed for sale, and one day when you're at home, someone knocks on the front door -- and then -- they ask you if they can take a quick look inside.

What to do, what to do!?!

First off, this does not happen very frequently -- so don't worry that you'll have people constantly coming up to your door when your house is listed for sale.  Most buyers will contact their Realtor or your Realtor to request a showing.

Secondly, if you don't feel comfortable having a stranger walk through your house just because you have a for sale sign in your yard and that gave them the boldness to request it, then kindly ask that they call their Realtor or your Realtor to schedule a showing.

But --- if you're comfortable with walking them through the home (and if I am your Realtor -- because I'm not trying to give you different advice than your Realtor if you are working with someone other than me) then feel free to do so.  More often than not, they won't end up being the buyer for your home -- but allowing a prospective buyer to see the interior of your house while they are excited about the exterior, location and/or neighborhood -- is, generally, a good thing!

So - don't dread the (probably very infrequent) knock - but just be sure to do what you're comfortable with in that moment.
