BRRR newbie - looking for advice on property comparison calculators

[Vikram V.]

Hi all - This is my first post!! I have been reading up/getting educated a bit on how to find a good investment property so I can get going. Seems like one of the critical tools in the arsenal is a calculator to plug-in parameters and compare various listings (by cash flow, projections over time, etc.).

Does everyone build their own investment property calculators (on Excel etc) to compare units? Or are there pre-built ones or a starter template that has worked well? 

Warm Regards,

Vik.
