You see, my family owns a beach house and then divides it upon ourselves throughout the year.

I have seen several properties owned fractionally from estates where someone divides property equally among a list of folks, often their children, but sometimes others. 

We are ok with the idea of doing Airbnb for a few months, but eventually want the house to be divided and to rent long term. 

It’s a 50/50 split on the business and with the property. 50% for me and the rest divided between my investors/partners.

Divide the list up into things that are $15 an hour items and things that are $100 an hour activities.

All of these things add up so just figure out what you want or need and divide it by 30. 

We will be able to divide 4 to 6 lots off the cul Descartes.  

Glad I asked about automation as I don't consider what you listed as automation but most every software on your list plus apartments.com which seems to be popular (well cozy was, seems to be divided on apartments.com) does almost everything you listed.  

Mortgages are mainly divided between qualified mortgages and non-qualified mortgages. 

Start with this number, divide by 6 and that's roughly the number of leads you'll need and your monthly marketing budget.
