So, you just check the cameras to see if you're having bad weather. 

They either had below mkt. rents or high vacancies and bad reputations and with super managing them I significantly grew the cash flow. 

Some people will say, "Take out a quality Insurance Policy and you will be protected."

You get so much wealth and start getting older you enjoy the business but focus on quality of life more and memories. 

But the answer for everyone may differ.Here are the personal attributes I see in those able to achieve a higher than market ROI, enough higher to be able to “scale”.1- Knowledge of real estate principles, real estate law and real estate finance2- Minimum 3 -5 years full time, or near full time experience directly related to real estate investing3- Ability to utilize technology for increased efficiency, capacity, and accuracy4- Excellent hired legal counsel and excellent hired marketing help5- Established method(s) of obtaining consistently high QUALITY deal flow6- Ability to manage and choose people who are NOT employees: Attorneys, Appraisers, Mortgage Brokers, Real Estate Brokers, Title Companies, Surveyors, Marketing Specialists, Accountants, Contractors, Consultants, Property Managers7- A VERIFIABLE track record of success8- Ability to identify, analyze, and negotiate a deal that can be “worked” for “enhanced” ROI9- Some type of competitive advantage; for example for me it’s my ability to analyze and identify mortgage loans that are actually less risky than all other lenders believe (on the investing in debt side), and on the real property side it’s my ability to analyze”pull the trigger” with LESS information than other investors need,  combined with the ability to pay cash, or raise significant capital almost instantly as well as being able to obtain loans at the lowest prime customer bank rate with no recourse or personal liability.  

Two things are certain, 1) taxes are lower today than they've ever been in the past 80 years. 2) they are certain to be higher in the future.We should all be focused on paying the lowest “lifetime tax bill” not the “lowest tax bill this year”.By paying 20% and settling up my long-term capital gains is not a bad deal.

Before the income subject to UBIT is calculated you can depreciate and deduct expenses and losses on that portion of the income so generally it's not as bad as people think. 

doing a bad deal just to have done a deal will set your finances and your relationship back.

It may not be a bad idea to also be added to a MLS search to receive any new build listings. 

I feel like it would be great to trust a property management company on all of this, but it would be hard not to step in if you could do a better job at screening bad tenants (eg screening HUGE future problems).I initially managed properties myself, but now I delegate that responsibility to my business partner, personal assistant, or a property manager at my brokerage.Most PMs I know will send you an applicant for final approval and you can get on the phone with them and ask them questions
