The books are totally full of crap copied from other books where the writers copied each others' ignorant beliefs and myths.

Thanks @Nick Brown, I would rather go further out than buy someone else's crap due to FOMO.

I don't take any crap from my tenants and I know it is better to get the poison out of my apartment building so I can enjoy owning rental properties.

, doors off hinges, broken windows--unreported and just left broken and open to the elements, heavier wear and tear on flooring than class B, large secret dogs that they are babysitting for a relative in jail for unpaid parking tickets, cigarette smoke smells indoors, broken shelves, home-made (crap) repairs on things, dead cars on the property, dead cars up on blocks on the property, piles of old bald tires, etc...Not all, but some. 

Hey; crap happens. 

Otherwise, use your big heart, give discounts and when you get hit with a huge bill for a roof, plumbing, or furnace you will find your tenants don't give a crap about you even after you discounted their rent for several years.

., but don't believe everything you hear and never pay for crap courses because you can get everything you need on the internet for free.One major problem investors have is even the brokers and wannabe professionals don't know how to analyze properties and they are full of poop.

If you don't put up blinds, she'll put something up and it may cause damage or look like crap (e.g. blankets in the windows).

You pay me and drive it away and 2 months later the engine craps out.

Won't lie and say I never fell into one of those traps and they are hard to avoid.Watch all the youtube videos you can watch, but be careful because a very high percent of the information is pure crap that seems to make sense only on the outside.
