I'm as confused as Don. (Runs with the name I guess) Are these loans for houses or commercial buildings? If they're commercial buildings, they're CRA reportable. You're providing the "permanent" financing in one fell swoop, but you are providing it. These aren't short term construction notes.
If they're notes on HMDA reportable properties...they're HMDA reportable. Again, it's permanent financing no matter what fancy packaging you want to place on it.
Now...ARE YOUR LENDERS NUTS!!! Think profitability and think of the customer. Construction loans are risky, hence the higher pricing and monitoring. They also typically carry fees that associate with that risk.
Take out financing is typically provided at a lower rate as the risk phase of the project has been mitigated after construction. They also carry fees for the bank.
Not wanting the client to sign again? That's a ridiculous answer. I've been a lender for many years. It's standard practice to have a construction note with term out. It's good for the client (reduced rate upon term out) and good for the bank (fee income and reduced monitoring). Smack someone with a wet noodle.

They've lost their minds!
