Where do you learn subordinate risk, from behind the senior or from being the senior

Be the senior first. The thing you don't know yet is how much slack there is in a construction budget, and you only see that from the seat that funds draws. From the junior seat you get someone else's version of it, written by a person with a reason to make it read well.

I manage rentals for a couple of investors who use bridge money to get places stabilized and I'll tell you what breaks: the exit date. Permits sit, the last tenant takes six weeks to place, the appraiser comes in under. None of that is fraud and all of it moves the payoff out by two or three months.

If you're junior, that's when you find out whether your extension and cure language means anything. So whichever seat you start in, ask the borrower what happens if the refinance is 90 days late and see if they have an answer or a mood.

Slightly different frame. The senior seat teaches you underwriting. The junior seat teaches you documents. You're going to need both, and documents are the cheaper thing to learn late.

Borrower here, a few deals in. I've used gap money twice. The lender I'd want to be is the one who called my contractor before funding and asked when he'd last been paid. That guy priced me higher than the other quote and I took his money anyway because he closed in five days.

The rest of it, first position versus second, mattered less to me than whether the person understood a rehab schedule. You can learn that from either seat, but you can't learn it from a fund report.

@lantern's split is the useful one. I'd add that being senior on small loans has a boring advantage: when something goes wrong you can act, so you learn what acting costs. Junior, you mostly learn what waiting feels like.

If you're the senior lender on a small loan, are you the one who has to deal with the second lien holder asking for notices and cure rights? Is that a headache you'd be signing up for on purpose? I haven't done any of this before, so bear with me on the basics.

@rigging not dumb, that's a real cost of the senior seat. You get consent requests, payoff statement requests and someone else's lawyer in your file. Some private seniors refuse junior liens outright for exactly that reason, which is worth knowing before you plan a gap lending business around them existing.

@tender, my own bias is patience, so I'd say do a couple of small first position loans that are boring on purpose and let the gap opportunities come to you. The pieces you're offered before anyone knows you tend to be the ones nobody else wanted.

Small portfolio, and the thing that broke for me at scale was always cash timing rather than value. Rehab funded in arrears, taxes due, insurance lapsing on a vacant unit. That's the demand gap capital is filling, so if you want to understand what you're pricing, go look at four borrowers' actual bank timing rather than their spreads. I don't think the answer to your question is a seat. It's whether you know what the money is late for.
