Questions about reserves for multiple properties

[Chris Lyman]

I am a beginner investor and am planning on following the BRRRR method. After recently speaking to loan professionals I have become aware of the fact that after you have a couple of properties lenders will require that you have 3-6 months of reserves for your loan payments for each properties on hand. I am interested in how savy investors handle the need for these reserves cutting into the capital needed for down payments?
