Almost 4 years ago I made a shift in my RE portfolio that made a big impact on my income and total net.

I suspect it will be as impactful as SB10 which means much ado about nothing.

A hidden expense that is impacted by capital gains is Medicare payments, if you are close to 65 or older consider the below:The monthly amount you pay for Medicare Part B and D is based on your Modified Adjusted Gross Income (MAGI) from 2 years prior.

The value of the property will impact this as well. 

Any body can refer me to an excellent RE mentor?

Other factors to consider are what you plans are for the future (value add rehab, restructuring, selling the property soon, etc) and whether or not there are any events on your personal horizon that may impact your ability to refi later.
