I'm also possibly interested in investing in other people's flips in the future, once I have more experience.I think I would like to eventually invest in higher-end flips ($3-$5M), but I would like to start smaller for my first flip, since I will most likely make some mistakes (buy for under $1.5M).

I love technology and believe you don't stay up with the times they will pass you by (eventually). 

Back to capex, remember, even a new roof needs replaced eventually, as does EVERYTHING ELSE, for the most part.  

It's hard to find any right now, but the market will eventually change and you'll start seeing more deals.

When you hang out with people who are actually doing deals you will eventually feel silly when you are the only one not taking any action.

Eventually...pretty much all of it.

This will then allow you to be very intentional in your journey going forward which can lead to your eventual success.

Find PMLs PMPs or buyers first and bring them deals, if you consistently bring deals they could eventually fund your flips 100% but they wont fully fund your first one and let you take off.

My wife got her Real Estate license to start looking for houses ourselves, and I was eventually able to leave my W2 job as a PT that I hated and despised, and because a Realtor as well.

What I am trying to avoid: renting for 2 years to eventually end up getting a condo/duplex later on or the flip side investing so much into a condo/duplex, and just overall not having it make sense with this situation.
