This is the rate banks charge other banks to borrow money overnight.

That way I can make sure it gets done, and cover the costs accordingly in the rent I charge.  

I think your lender is charging points to give you this rate, which I would not agree with.

I guess I will be charging the late fee of $25, plus $75 per week.

Some Community banks limit the number of Properties (or $) to each Legal Entity or charge Audit fees to review your LLC structure.  

(Of course, you don't have to tell them you are charging above-market rent, but they will know it.

So, the most I can charge at move-in, without collecting an “option fee” (which might be construed as a “down payment” and therefore deem it an installment sale), is 3 months rent.

When I saw the charge on my credit card for the month of November for the following year, I immediately called Property Radar to cancel and asked for a refund for the 11 remaining months after cancellation.

I can't get an answer to this question: rather than paying their charge of $1,400-2,200 to create a Traditional IRA LLC plus another $1,400-2,200 to create a Roth IRA LLC, I want to create two new cell/series in a Texas Series LLC to save myself the bulk of the setup and ongoing LLC costs. 

All your cards are on the table.
