The total asking price for all properties is about 1.4M with a current gross annual rent of about 228k (all rented and cash flowing except for one property, two of the properties have a "rear" house with it).

Once you have no annual lease, by law you automatically go to a month to month lease.  

I have one person on the payroll and it is an annual subscription.

My goal: In 10 years, generate at least $150,000 in passive income annually (i.e., 40 doors with >$300 NOI per door per month)My target properties: SFH & small MFH in B areas (I should be comfortable with my girlfriend walking through the neighborhood at night).

While it has a large annual fee, $450, they give you back $300 when you charge anything to do with travel.

I did not - and do not - have an SSN.I had three international students rent a house (a brother and two sisters), when I asked them to demonstrate their ability to meet the financial obligations, Papa transferred more than the amount of the total annual rent into an escrow account.  

One lender is offering us a variable annual percentage rate of prime + 0.50, with no fees and an option to fix the rate on a drawn portion at 0.50% above the variable rate. 

If $1M in assets isn't providing $100k annual return or value, it's time to reassess the utility and leverage-ability of those assets.

I'm thinking that I should charge 150% of the monthly rate that an annual lease would be - this would still be less than half the price of an extended stay hotel , and do it as a vacation rental, with the entire rental period paid up front. 

@Chris Lawrence - we use a short checklist for quarterly inspections and a longer one with 120 items for the annual one.
