gross receipts mark that has to be hit before you're required to file Texas franchise tax.You probably are still required to file an annual report for the LLC with the state but other than that you wouldn't owe anything to Texas.  

The builder marks up 10% to hire a general contractor who marks another 15% to 30% who hires a subcontractor who makes it up 20% to 50%.

I found out later that they were marking up repair costs by 20% which I did get returned when the contract ended, but the only reason why I even found out about this was I got a copy of the original contractor receipts (which they refused to provide me with) at the end of the contract and discovered that all of the bills I paid were higher than what was charged. 

Rental guarantee's usually Imply a fairly large mark up from true cost ( need to pay that rent guarantee from someplace.3.

At this point I am convinced this is being done intentionally to collect money on fees and higher interest when the loan matures after the 90 day mark.

Typically, when doing an installment sale, does the seller (me) charge "interest" on the outstanding balance, or would I simply mark up the sales price to some fixed amount (which of course can be calculated using a target interest rate).thanks.
