REPE Fund Portfolio Modeling

Does anybody have a decent fund management model template or recommendation for consultant-type firm? Anybody try out REFM's model?

I'm decent at excel, but the modeling required is a little above my skill level right now.

Here's complexity I'm managing. I'm modeling realized assets, unrealized assets with projected returns/distributions, and a pipeline of acquisitions with estimated holding periods and returns, which changes often. For the fund there are historical actual expenses, forward projected expenses. Actual and projected capital calls (dynamic based on pipeline), which drives fees, also option to do short-term credit lines and not have to call capital. Reserve accounts to hold cash from dispositions and planning to re-invest in acquisitions or distribute to investors. Acquisitions are cut-off by investment period, then a window for re-investment period. Then the whole waterfall aspect of splits for LPs/GPs with hurdles at the end of the fund.

I could pay or exchange some models, just don't want to drop $1K on REFM or consultant to realize it's a basic promote waterfall with static inputs.
