I use HAR to find properties.

TAR, TAA (that's the Texas apartment association who should be most vested in the issue), HAR none of them put good details on what constitutes the ESA requirement. 

We can effectively elect to group all of your rental activities as "one" activity so your spouse must only show she participated in the "one" activity (all of your rentals) for a total of 500 hours.So your spouse can be a real estate professional, but you will need to group your rentals into one activity to harness any real benefit unless she strategically materially participates in two or three rentals for 500 hours per rental.The grouping election by the way requires that you group ALL of your rentals.

We use HAR a lot, but I wondered if there are other suggestions for websites with helpful local data.

I believe it's more along the lines of if you are successfully completing transactions without issues, HAR/TAR won't bother you much.

Too steep to walk on use toe holds and harnesses are a nice feature.

Use the HAR lease. 

Once you get licensed, if you dont sign up with HAR and get MLS  access, after 6 months or so (When they catch it) they will make you join, or else they deactivate your license until you do.
