Dan,

The professional thing for the realtor to do is to contact the people 
who created the ad to get the original files. It is not quite correct to 
say that the Realtor owns the ads. It depends upon the contract with the 
  person or persons that created the ads. Moreover, an ad could contain 
a photograph, graphic, or logo whose usage is restricted. If you get the 
original files, then recreating the ad for website use will be much easier.

When posting to the web the dpi used is usually either 72 or 96 dpi. At 
those resolutions many scans will not look great. Text looses its 
crispness and other problems arise. If I had to reproduce the ad, I 
would scan the artwork and use that as a base for recreating the ad.

Depending upon the ad a jpg or gif would be best for the graphic 
material. TIFFs don't display on webpages. PDFs are ok, if you are sure 
your audience will have reader. I have sometimes uploaded two versions 
of an ad and let the user decide if they want a jpg or pdf.
