What formula is used when calculating price of property + property taxes + expenses and upkeep - what property will rent for = monthly cashflow?"

I would calculate my numbers by putting every dollar from the rent into my RE account. 

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

We're incorporating the prop taxes & POS costs into our overall calculations.

When you calculate the 2nd criteria you find the following:$1,000 (rent) + $500 (car payment) + $250 (child support) > $3,500 (gross monthly income) x 45%$1,750 > $1575So, they do not qualify because their debt is too high.

Upfront expenses and monthly payments must be considered when calculating the return on your investment.EXAMPLEYou cash out $100,000 of your equity and use this as a down payment on a $400,000 investment property.

When I purchased it I simply based my offer on the numbers that made it work using the BP Calculator.

BiggerPockets calculators are great, but practice analyzing deals manually... know what your cash-on-cash return should be and how different financing scenarios impact your returns.Curious..are you thinking about a property that’s fully turnkey, or would you consider something that needs light rehab for a better deal?

I wanted to check the calculations that are presented in James Dainard's book, The House Flipping Framework: The Tactical Playbook to Scale your Real Estate Portfolio and Reinvest your Profits.
