They'll want all the money spent on the main house, lenders kind of ignore ADUs it's weird. 

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

My favorite ones (as a Contractor) are those like : "How much will it cost to re-wire my entire house?"....."...

@Shane Regnier I've flipped a bunch of houses in Ocala but have yet to dabble in the rental market. 

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

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. 

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

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.
