We have an investment coming together pretty quickly and we do not want to do an additional capital call because the fund is not fully closed. What are my options?

One thing you could do is to write a small check from the fund and offer the rest via SPV to your LPs as a perk. You can use Decile SPV for this because it’s built for this use case and is managed in hub.

Important: Capital lines of credit from your bank are NOT an option in this scenario because you have not closed the fund. Banks are not going to provide your a line of credit due to the risk and it's not cost effective.
