This has driven up the property taxes there. 

My endgame is to end up with $300k/yr in post-mortgage income in 20 years based on investments I make now followed by continued investments over the next 10-15 years own.

I'm in the market for entity config and tax planning/prep.

If they are self employed and their income on their tax returns is understated because of deductions you can use data from bank statements.

Will the property taxes skyrocket?

For example, what is the monthly revenue for the property and what are the "All In" expenses, including mortgage, taxes, insurance, utilities, repairs, etc...

Investing in a mortgage fund should not have tax implications for your Roth IRA since the investment is passive. 

The units are all currently occupied right now, so we won't have to worry about the buyer's market right now haha.With the cash flow I will receive, it will be enough to take care of property taxes, insurance, and enough to save up for any emergiences with the unit that I will need to take care of, so no need to worry, I got you :)!

(I REALLY can’t stand state income taxes.  

Last but not least....A few members in replies have already mentioned why it makes sense to hold…….I very much appreciate ALL FEEDBACK, however I think it will be helpful to provide some added context as to why I am absolutely certain (and my CPA’s are convinced as well) on my decision to liquidate the entire portfolio and onceAs I educate clients on daily, income tax brackets as well as long term capital gain tax brackets in our country are more favorable right now than they've been at any point in the past 80 years.
