I restate all of the critical information that I know they will be asking about (even though I put all of that same information in my ad) as well as include my rental criteria. 

@Ada Tor I would recommend a personal umbrella policy of at least $1M. 

Even if the dog is a service or emotional support animal, the reasonable accommodation clause in the ADA allows you to deny applicants if your insurance will not cover the breed (even in California!). 

This has made my marketing a lot more time intensive as I end up cut/pasting my carefully crafted ad as a personal reply to every single email I receive from that site. 

STRICT compliance with ADA is imperative, and additional 'comforts' including elevators would be almost definitely necessary.

@Damon Saxton You could ad a picture and have some properties with some reviews.

Going through an ADA issue with a front door on a retail place I own - I know the routine regarding "connections" in SF lol...

If you are unlicensed I would pretty much dare someone to take out a TV ad a property they don't own.

The ADA requirements are very specific: doorway widths, length of handrails, amount of space on stair landings, emergency alarm in shower.

You'll also want to check with City zoning to see if there are any other things that must be done to the property before leasing to a commercial tenant (think ADA, etc.).
