Advise for someone starting to model deals

[David Lasky]

I have been analyzing a lot of real estate and business deals for the past 5 years personally. I have been doing a lot more financial modeling since we have been shut down. I would love to put this knowledge to some practical use outside my own investments. I am a light on cash due to the shutdown. But I think I have a marketable skill to help people analyze deals. Don't get me wrong. The Bigger Pockets calculators are great! I love using them. If you haven't used them you should. My question: Is there anything that you would watch out for when building models from scratch? How detailed do you get? I'm still learning to do it right. I just love building these models. Any tips on how to build models that other people could use?
