I am interested in a Series LLC, understanding trusts, and acquiring optimal loans while maintaining security and anonymity.Please let me know if you require further details,    

Given the cost of turnover in this case, it's often better to solve for total vacancy/turnover costs rather than just optimizing rental amounts.

Make sure that the firm you talk to is also competent in tax optimization as the structure needs to meet both asset protection and tax optimization at the same time.

If so, what areas are optimal for a good cash flowing rental (minumum vacancy rates)?

It's best to consult some pros who can look at your overall financial picture and advise you on the optimal structure.

All of the part time, or one-off STR owners just don’t have the same experience to achieve actually optimized STR results.

Interesting, how often do you optimize your listings? 

Excercise to me is no different than eating or sleeping for maintaining optimal performance..... it's a requirement.I get up every morning between 4:30-5:00 and do an hour of treadmill, elliptical mixed with weight lifting on certain days. 

@Matthew PerryI have a goal of owning a 10-20 unit multi family asset by Q2 of 2020.Working backwards my goals for 2019 are:Q1(1) cash out refinance out of my two current BRRRR(2) get into a fourplex with potential to cashflow 200+ per door(3) set up QuickBooksQ2(1) big vacation(2) optimize the fourplexQ3 and Q4no idea.

I’d say about $20k monthly net after tax cash flows from real estate investments, but since these would be leveraged some still to optimize returns I would be looking at most likely $40k+ net profit from real estate.
