Heloc investment first time

[Stephane Bede]

Just got 115k heloc on my first home. I am newly to the property investment world and would like guidance on how much I should invest in my first rental property? I live in Massachusetts what should be the approximate amount I should be spending on a rental property to generate enough cash flow to repay the heloc and be able to repeat the process to acquire more property?

After acquiring my first property, what should I do to acquire a second rental property?
