Even if I'll live in this duplex, I plan on only living in it for a year.

Do you plan to refinance after adding the value?

I also open a solo 401K plan.

Many beginners jump in without a plan leading to mismatched goals and markets.

If there were issues with electrical and sewerage, does home insurance cover that?

And, since I can have an insurance policy on my properties, why would I buy treasuries?

Here are some of my next recommendations based on your current BP Profile Bio:- Listen to the BP Real Estate Rookie Podcast (https://www.biggerpockets.com/podcasts/real-estate-rookie) - Read "Set For Life" by @Scott TrenchI see that you are about to graduate college and plan to become an Army Officer by May 2025!

Try out the BRRRR (Buy, Rehab, Rent, Refinance) plan to grow your list of homes fast.

I think it might make more sense for me to continue to rent my current apartment due to the conveniences and being able to walk to work versus moving into one of the units in the multiplex as I had originally planned.

But realize that there's time involved to prepare plans for city submittal - that can be anywhere from an hour to a couple of days, depending on the complexity of the project.I usually eat the cost of contractor licensing for retail clients, but I might pass it on to an investor client.
