Recommended residential mesh wifi setup with remote admin?

[Cliff H.]

Looking to install a new mesh wifi install in a larger, residential 4BR rental to provide a more reliable infrastructure for contractors, lease turnovers, and remote monitoring for all-utilities-included leasing contracts. 

Any of you have personal recommendations/experience with any of the newer mesh wifi systems? If so:

• What type of rental are you using in it (type/sqft/levels/etc)?
• What level of remote admin/functions are you leveraging in your setup? 
• How are you handling equipment failures/replacements (on-site engineers, service contract, etc)?
• How are you handling initial setup/wifi design?
• What things do you know now that you wished you knew before you installed?

Thanks in advance for any experience/insight you can share!
