It sounds like a single family house where you will be living in the house(personal use).Therefore, you may not be getting the tax benefits you think you are.Consult an accountant.I am not sure why your sister would agree to this as well, she is losing $170,000 in this transaction and she faces the possibility of you increasing her rent.You also have to charge market rent or close to market rent or it is all deemed personal use.

We negotiated a deal with the owner for 20% Equity, we are responsible for infilling the community as well as property management (which we also get paid separately for).

I might sell some units as well. 

And yes, the income from renting is still taxable, but ideally you are offsetting a chunk of that with depreciation which is a non-cash expense.You should read Amanda Han and Matt MacFarland's books as well which are available in the BP Bookstore. https://store.biggerpockets.com/products/tax-strategies-book...

We have sold (tax free), kept as long term and/or short term rentals as well.
