Same thing with bank accounts, utilities, etc.

As I'm sure most of you know, a long-term rental is simple since the only recurring expense I own is the mortgage, whereas with a STR I'll own the mortgage, internet, utilities, furnishings, cleaning fees, etc. which just makes my projections a bit foggier.I'm looking for feedback on the below expenses and wondering what else I should be thinking about, that I don't currently have listed.

After utilizing the Do Not Call Registry for phone numbers, my list is cut in half, to about 3,000.

Are they sitting on concrete foundations with full utilities to each?

There are strategies that you can utilize here that can make it easier as well. 

I start with cleaning and repairs, then I apply it towards utilities, legal fees, late fees, and rent, usually in that order.I also have a holdover clause that says the tenant is charged 4x of the monthly rent, prorated daily if they hold onto the property after lease termination.

Did they have bank statements showing utility payments for the rentals?

I've been getting a card or two a year to increase my limit (indirectly lowers utilization as well if you don't charge it up) - it does hurt the overall credit age though 

Thanks,A lot of lenders (mortgage brokers) utilize figure https://www.figure.com/home-equity-line/ if it helps you at all.
