@Jo Zhou Seems like you got your answer via the insurance company.

The City of Independence stated that they have been trying to get USREEB to fix the issue for almost 2 years & I was never even notified of such issue.The tenant moved out Aug 2017 & the property management company kept charging me utilities upwards of $400 when the property was vacant & did not/could not provide me proof or answer why.The bottom of the kitchen sink cabinet was missing & had fungi growth that was never cleaned and replaced.

However, they should still be able to provide you answers to any questions you have about your investment, which I'm not sure they might be willing to spend time on. 

In addition, they want and need answers to their questions in a timely manner, not some e-mail address to send to that will get back to them in 24 to 48 hours!

I've searched the forums and can't find this answer.

The best and fastest way to get your answer is to talk to multiple property tax protest firms, you might be able to fish for your answer or at least you could hire them and they can take care of it for you.

Short Answer = Yes it is Possible and I know several people who have done itThe Long Answer = The only way I have seen people with no money get started in Real Estate Investing and be successful long term is to get very good at finding motivated sellers.If you have no money, no credit and no experience but you have the Super Power of finding and attracting Motivated Sellers I promise you that you will also attract deep pocket investors who will partner with you, give you finders fee's etc.You see the hardest part for most people is finding the time to seek out motivated sellers as you could talk to 500 people before you find even one possibility and for most people they give up after the first 50 No answers.I wanted to share this with the new investors as I have seen too many of you get excited and burn out with no progress after 6 months. 

I've searched the forums, used the BRRRR calculator, watched BP Youtube videos but haven't found the answer. - How does my HELOC factor into my calculations below? 

And when my neighbor inquired in between when he'll get to it, his answer is "I'll get to it when I can, but if you find someone else in the meantime, it's OK"So how do you like that for enthusiasm, and the contractor is doing a favor by taking the job.

To answer your other questions, I just write my own as a lawyer.
