is this appropriate to do in an online ad marketing the property?

[Katy Nguyen]

In a FSBO scenario:

The seller places an ad for the property online.  Photos of the property and the specifics of the property are shown.  The ad states the property is being listed at X dollars per SF.  Two questions:

1) In the ad, is it appropriate to give Zillow links to a few comps showing how much similar nearby properties were sold for in the past  3- 6 months? 

2) In the ad, is it appropriate to give Zillow links to a few nearby current listings to show how much similar nearby properties are being listed for?

Thanks.
