Cash buyer looking for 10% Roi

[Ronnie Monroe]

Hello all

I am a new wholesaler and Im cold calling cash buyers in my area and asking their criteria to match them with properties I find. One investor said they want too get a 10% ROI when the property sells. Does anyone know a formula to ensure you lock up the property at the right price to ensure the cash buyer gets the desired outcome of 10% ROI? Thanks in advance!
