Seems a bit high on the exp ratio near 43% but we do pay a premium for our solid cleaning lady, she also stocks supplies, runs errands and other duties for no "extra" charge.

If so, are your amenities worth the extra price?

Typically this means they will take longer to close, may not have all the information for the companies they work with, and most hard money brokers get their money by taking an existing product and adding extra points to pay their fee.What is your investor success rate?

They had been paying those extra taxes for ~10 years since the last tax reassessment.

What are you hoping to get out of the extra time, work and costs of having the LLC?

It's easy to obtain, costs very little, and doesn't require extra, on-going effort to maintain. 

I’d plan for extra amenities like special decor or concierge services. 

It would also have to be put up and taken down between each tenant and I don't know how responsive your PM will be to this extra work. 

The least states:"Tenant shall pay a "late charge" not in excess of five (5%) percent of the amount in arrears for each month the arrears remain unpaid if any Rent is paid more than ten (10) days after the due date thereof, to cover the extra expense involved in handling delinquent payments.

They don’t charge anything for these extra accounts, my tenants pay directly into those accounts.
