Getting major negative cash flow on deal analysis

[Felicia West]

Hi there.  I’m a new investor and have begun using the rental property calculator on bigger pockets for my market.

I've only analyzed about ten properties so far, but I am getting about negative $1000 cash flow per month for most of the properties and negative cash on cash return. The properties I am looking at are on the MLS because I feel I do not yet have the skills needed for off market deals

These numbers are even with a 25-30% down payment.  I am using 5% for repairs, 10% for cap ex, 10% for vacancy, and 10% for property management.  Are these the numbers you use, or what am I doing incorrectly?  I definitely do not want negative cash flow on a deal.

Thanks in advance for any insight you can give!
