How would you recommend we vet the brokers beyond what we mentioned above? 

Biggest challenge was the two end buildings were added to the historical registry so I had to obtain historical commission approvals.

I would highly recommend doing a renovation loan like the 203k or homestyle - you are able to leverage SO MUCH CASH for such a low down payment. 

I've seen the Speed Queen SF series recommended in a few places.

An attorney recommended to drop it.

Years ago we didn't require it and just recommended it to the tenant, but it's so cheap and gives our insurer something/someone to abrogate against should we have to make a claim that we don't allow it to be optional anymore. 

This way, they’ll have a vested interest in maintaining high standards of management.To truly understand property dynamics and support the management team, I recommend spending time on-site.

Then, I would recommend connecting with STR specific realtors in a given market.

Recommend:1) Speaking with a landlord-tenant attorney about your options2) Keeping an eye on the property -> ask your old neighbors to do so if you are too far away.3) Try to do a surprise visit to catch who else may be staying there.

Some carriers require limited water damage coverage depending on the age of the property and age of utilities.I would recommend at least 25% (ideally more) when possible and if you're limited to 10% you should make sure you cannot purchase another policy for a similar price.
