Property taxes run about 1.5% in Ada County.

You'll ad a link that sends them to an opt-in form to collect their information. 

I plan to make this a regular ad as long as it is not to cost prohibitive. 

The carrier has to tear it all down, dispose of it, pay soft costs and upgrade it to current building codes (ADA, green building codes, AFCI, sprinklers, etc) that could be much more costly than the original construction.

I would look up ADA requirements at the federal and state level.

Is the property ADA compliant?  

The Building consists of 7-2 bedroom units and one ADA accessible 1 bedroom unit. 

I am wondering if there are any commercial brokers out there who routinely use a company/inspector to provide ADA compliance reports for their buyers/sellers...more specifically, in Arizona. 

That's 10%, and for reference, half of that (5%) or even less is plenty for water drainage on soil away from a house  -- but when you're talking about sidewalk, realize that max ADA cross-slope is 2%.  

Any such disqualification could violate ADA.
