Generally speaking an investor collects rental income and signs a lease with a tenant whereas a flipper or developer shows "inventory held for sale" on their books and gets all of their economics derived from a SALE.

It works effectively with visitors - 125 pages, a blog, 2 e-books to collect E-mail,...Let me repeat my advice.

The biggest issue for them is that quite often Class D neighborhoods attract Class D investors, Low life investors who think that they can buy for pennies on the dollar, invest peanuts into the rehab and then collect free income from the government for years to come.  

Which is the core of my question in the start, does it matter for the lender if I pay directly using the LLC's bank account that collects the rent or I take that money out from the LLC to my own they pay as I do now. 

If you just want to buy rent ready properties and start collecting rent I would caution that you don't over leverage as you will only increase your cap ex spending all while eating into your cash reserves/equity.

Also (very important) when STR online portals (Airbnb/VRBO etc) will collect tax and send it to your local govt along with the address for which it was collected.

How else will you be able to possibly pursue collections without SSN, job & bank info?

So I am seeking advise on platforms to advertise the units, how to vet potiential tenents, how to create a lease agreement, how to collect rent, and any other helpful tips/advise that anyone would have. 

If it's a three bedroom you can collect rent for two bedrooms, especially college students.

If the properties are split into an LLC, then each LLC will need its own accounts.Checking: collect all income here, then use it to pay bills.
