Yes, in theory a person can make CRAZY $$$$, and some absolutely do. 

None of this has anything to do with your personal tax return.

I was fortunate enough to live in Detroit for several years, so I was able to establish a network before moving back to California.

I personally would sell it.Your return from real estate is two items - Cash Flow + Appreciation.What is the annual rate of appreciation you are getting, approximately?

The vast majority of contractors won't want to give bids on properties while under contract unless they have a relationship with that person from prior jobs.

That will be the best spot to meet an investor friendly agent in person or at least meet other investors in your markets that can help connect you to the right agents.

On more than one occasion I’ve talked with a person or two that was offering real estate coaching and I found out very quickly that either it was not what they were advertising or they was not far enough along to be coaching anyone except maybe a complete newbie or maybe it wasn’t the strategy for me.Anyway, that’s my ramble for this morning.

Imagine making millions of dollars over the course of your career and then having to pay 30-50% every year to uncle sam instead of compounding that cash over time.This is exactly what real estate professionals have learned to mitigate.To reduce their taxable income, they just buy a building every year, do a cost seg, and use depreciation to reduce their tax liability dramatically.Their personal wealth snowball grows much larger and much faster than their W2 counterparts who give most of their money back to the government each year.Following this strategy as a real estate professional is one of best ways to end up with a much larger net worth at the end of your career.

I have not done it personally but have some insight, maybe my reply may boost your post to someone with more experience in it. 

Personally, I would pay off the higher rate first.
