Wealth building fast with property

[Bogdan Masca]

I need to calculate the roi in an excel sheet i need the formula. say i`m buying and flipping and buying and renting. i saw that for buying and renting i`m making about 8% per year. if the property value increases with another 8% per year how much will the property be worth. I bought a property worth 100.000$ for 80.000$. i`m getting a rent of 600$ a month for it. no mortgage.if the property value increases with 9% a year what will be the roi on my networth in a year.

Also same property bought with mortgage

Calculated this way but at a 20% discount how much will it be worth than with the ROI. I have 20k positive cashflow didn`t have to invest in the property for fixing it. how many years will it take if i have a mortgage on it to get to 100% 3 years or 5?

I need the excel sheet formula
