How to calculate future value with rent increase?

[Michael Bellizzi]

There has always been one formula that has stumped me and I am hoping to get answers from someone wiser. How would I calculate the future value of a property if given a known rent increase over a set number of years? For example, If I had a 10 unit building where I knew I would increase the rents 25 dollars per month, per unit, for the first year. What would that value my property at in the following year?

Thanks
