Used PSI last year, they did a bad job, the snow wasn't even bad last year and with several attempts asking them to do better within the terms of the contract, they still sucked. 

I’ll be honest it’s not clear to me real estate is necessarily a better investment than say the stock market, certainly not a bad investment but not as hyped as some people make it, you need to decide how much owning your own home is worth to you & also how long you plan to be in the area, if you will be here for the foreseeable future, bite the bullet and buy, if your not sure where you will be in a few years, renting might make more sense.

Yes - and even when its out there its typically impossible to qualify (need high rate and high DSCR and typically would have to qualify as a LTR - so almost a unicorn or in a really bad market)

There are two reasons this is a bad idea.Investing with an SDIRA (assuming it is not a Roth) will often result in paying significantly more taxes. 

Landlord had to move to a different state to have better access to healthcare, i.e. did not move by choice per se.

It includes a lot of good/bad examples.

It is better to have a vacant unit than a bad tenant. 

-- depends on your risk appetite but leverage can certainly pour gasoline on your real estate investment fire in both a good or a bad way. 

But can anyone here actually speak from their OWN experience as to why NWAC is bad?

Of course, if I was a bad boy, just let me know what I got up to that caused the issue.
