@Kyle JosephThere are plenty of models out there.Many are free or low cost.The real issue is knowing your market - rents, vacancy rate, expenses etc.The magic is NOT in the model but rather the data one enters into the model.Agree with @Chris Seveney

By following the BRRRR method, you'll end up owning free real estate.

I'd recommend using free trials from the softwares (Propstream, Batchleads, Property Radar, etc) and trying out the filters to see what would work best for you.

I have a typical part time job, but was looking for either a job or to work for free somewhere that I will learn about the real estate market. 

Feel free to DM if you have any questions :)

If you need any assistance, please feel free to give me a call.

Many of the property owners we work with are out of state owners, feel free to reach out if you would like to talk.

(A 3 family would be 4 units counting the exterior, so use $24,000 as a base number to negotiate with.)There;s also a database online you can check to see if the unit has ever been inspected.Good Luck!

Does anyone know of a rental analysis calculator type of thing that is free?

When I went online to check them out, they seem to be affiliated with other lenders too.
