We have learned to adapted.

You must adapt the information that makes sense to your situation. 

Don't quit, adapt!

I say you need to be flexible and adapt to the market and what the market gives you. 

But if requirements floow through, you'll find lenders adapting, working smarter, seeking better financing, performing better underwriting and thereby reducing servicing costs.

I can't thank you enough for putting the time/effort into such a clean product just to share it for free.My question to you is do you have a similar tool for analyzing simple SFR or MFR deals, or is there a way to adapt your BRRRR sheet to do that?

We will adapt. 

I don't advocate learning one or just two systems, markets and conditions change, if you can't adapt to the right strategy to the property you will have limited yourself.

I would adapt the eventual thing I would build to the market.

And not tied directly to one particular market and that allowed it to adapt with the market.
