Guys, I've booked a couple of MCAs here or there.... I'm mainly a real estate guy (past 20 years) - I specialize in: Hard money bridge, rehab loans, 30 year DSCR loans-no tax returns, and some commercial.

Question 1: What's 2nd - 6th position MCA signify? (in real estate 1st position and 2nd position mean they were recorded on title in that order and must get paid off in that order in the event of a sale, a 1st position = 1st mortgage, 2nd position = a 2nd mortgage, etc)

Is this similar in terms of MCAs? Is this reflected somehow in the UCC filing?
Can positions be paid off in any order?
What's the benefit of NOT recording a UCC filing to the merchant - it seems it would be in the funder's benefit to record a UCC --EVERY-- time? Why wouldn't they?

Question 2: Is the MCA space back and running on all cylinders? (I was considering diversifying because real estate loans can take weeks or months so I'm looking for a "short game") I used to use BFS, Yellowstone, etc... (though I see BFS sold to some technology company)
