And I worked everyday, ate almost every meal at home with cost effective foods and sacrificed 90% of my social life to be able to save the way I did.

In many instances like this one - by the time it gets investigated damage is already done I love these articles not for the fact investors are getting abused.. but the statements about lavish lifestyle  fancy dinners etc etc.. every single white collar litigation or criminal complaint has that exact same language.. and now you know why the Mafia guys just lived in some plain Jane home and maybe drove a caddy and ate at a low end restaurant LOL.  

That being said, I seem to be doing better than most.I had a couple large ticket items to fix last year that really ate into my profits, but I still ended up positive and with a great retreat from the city that pays for itself.

Like Super Mario Bros. the rent ate the mushrooms and grew larger in size! 

Eventually went to Goodwill for my clothes, ate bologna sandwiches for lunch for years (I don’t/won’t now, lol), cut my own hair (still do, because I don’t have a lot of it anyway), we refinished garage sale furniture and sold it, we shoveled driveways, then got into online sales of dvd/blurays (still do it) weekends and nights sending stuff out.

I felt like I had a decent January but then added charges from my rental company ate up all the income, so I guess I'm trying to do my due diligence now.

I think the expected maintenance issues (plumbing, HVAC, and the like) really ate into cash flow that I developed over time and has kept me at a plateau-like position.

I want to take $100k out (less than 75%.Is there an ethical problem and what ate tax implications.

That sucker ate my lunch to the tune of $3K a month for ten years. 

This is most likely exactly what is going on - the 10 cap is rarely ever hit because the metrics, hassle and complications of qualifying often becomes too much (which also ticks up towards worse overall terms which can include fees) - the math makes a lot of people to move towards Non-QM/DSCR right about this exact point (I generally always point to "property number 5" which looks like you situation to a tee)
