Option 1: 21 year old signs up for Bigger Pockets, house hacks, networks with successful real estate investors, learns how to best allocate his money, after 5 years doubles his income through smart investments, by 31 is financially free from the shackles of employment for the rest of his life.Option 2: 21 year old signs up for Bigger Pockets, decides to get married and not invest because he believes in "happy wife, happy life", resents her because his money is spent on unnecessary square footage in the perfect home, multiple cars, and vacations, and he doesn't satisfy his urge to invest.Which one is best FOR YOU?  

It may seem unnecessary to setup a process like I mentioned about for only 3 units.

As investor in buy side we also don't want people to lose money or having unnecessary higher risk in their purchase.I would pay cash if it's special property like there's gold beneath it and/or STR in Phuket where mortgage is not attainable, but for just hundred bucks cash flow out of midwest LTR, why I shall sacrifice one hundred k ?

Himy neighbor contacted me with his plans to replace fence , however there is no issues with the fence common to my and his home, and I don't see any reason to spend unnecessary 3k to replace something which has no issue. there might be issues with his other side of fence, I have no idea, as his house is behind mine.how would you handle the situation ?

Quote from @Julie Garner: Unnecessary.

We do include a warranty on all major systems, so the 2nd one is just as important to us, as we don't want the exposure of unnecessary repairs. 

Landlords are best served when they don't allow their tenants to pull them into unnecessary drama and babysitting.

My gut tells me that would be unnecessary but we will see. 

Why not simply wait and find a property that is actually below market value so that instead of paying an extra 6k, you end up saving 30k etc because you bought at the right price, all while also eliminating all of the unnecessary risk. 

Money Mustaches of the world believe that cutting unnecessary expenses not can not only quicken your journey to financial freedom, but can also release you from the chains of materialism and enable you to live a more engaging, rewarding and environmentally-responsible life.
