I would suggest making sure that you are following a set format/style of house each time you flip to systemize it more2.

That being said, if you're 23 and you don't own a home, I really do recommend starting with a house hack as you don't need the 25% down capital to get started and you kill 2 birds with one stone by getting a rental and having a roof over your head. 

There is also an ad on small "house" which is also being rented.

@Tim Holt, Yes INDEED house hacking is the best option for most 1st time buyers.  

While I own a house in Canada, which has been my only investment so far, I am eager to diversify my portfolio and begin investing in real estate in the USA.

One thing I continue to think about is how valuable 2-4 unit properties are becoming, and will continue to be, since Fannie/Freddie took the income restrictions from the 5% down conventional loan option for house hackers. 

Also, before you buy another property you'll want to determine your ideal next property - meaning, will it be a "rent ready" house, a major renovation project, or somewhere in between.

If I am house hacking then what should be the insurance.

However, they go to far in being different.Your house looks great!
