When do you accept your profit?

[Chris Wilkening]

Recently bought my first rental property. After all expenses it should cashflow around $157 per month. 

My question is when do I withdraw the profit? Ideally the reserves would cover anything that came up, but you never know when a large unexpected expense comes up. 

I'm saving up for house 2, do I take my $150/month and move it into my savings account? Or should I keep it in the checking account and withdraw the profit once I'm ready to buy the next one. Seems a little trivial but wondering how you all handle this.

Thanks!
