Responding to realtors

[Eric O'neil]

It was suggested to me to get used to running the numbers/ analyzing properties that I might be interested in. I'm using the BRRR Calculator and I'm wondering if the same questions the calculator is asking me, I should request those same questions from the realtors prior to them sending me any information? Should I also volunteer the fact that I'm a first time investor? And most important is there or are there any specific question i should ask to be able to input to the calculator?
