Question about financial models

[Omer Esiner]

This is more a question for fund managers/syndicators:

Do you build your own excel models or do you outsource? If outsourced, where is a good source?

I'm setting up a small RE investment fund focused on buying run-down homes and developing new SF homes for sale. All the models I've come across tend to be cash-flow focused. I'm really looking for a simple model that give me basic stats like cash-on-cash return, ROE, IRR following a waterfall. Very simple- GP and LP's, no hurdles. Just buy, develop, sell and distribute the profits.

I have some basic models I've built but I need something a bit more polished for investor collateral.

Any help would very much appreciated!
