The easier it is for someone to click on something, the less likely they are to be a serious customer.

The $1,550 is the max they'd be willing to go to if that sub-market and neighborhood comps can support $1,550 plus.

For now all you are going to see is more of the same because the vast majority of inventory is being held by people with 4-sub 4 rates and they can't/won't want to afford elevated prices and 6+ rates.

What scale should I be at to explore sub to? 

Real Estate CRM software stores organized data about leads and customers, such as personal information, communication, and purchase history.

I'm hoping they get a good director in place who wants to serve their customers (tenants who need safe houszing) and their vendors supplying that need (landlords) and operate an efficient and successful program serving our community. 

If the property is sub-metered/ if you intend to have the tenants pay utilities make sure to mention that to them. 

Yes, and separate bank accounts as well, or at least sub-accounts.

You can customize the approach to your own needs.

I recommend hiring either a PM or even a listing agent who you pay a half a month to a month of rent to get the unit rented.Just so you are aware, these tenants are your customers hence if you make the application process challenging and tedious at the very forefront of the process, most people don't got time for that.
