I'm particularly liking the idea of a dulplex, and "House Hacking". 

That's correct, I spend $140 per month on QBO ($90 for one LLC, and $50 for the other) plus my bookkeeper that averages about $500-$600 per month.Great idea, and yes I would do a trial for a few months using both.

There's actually some deeper nuance here than just the holding period. 

Collecting a refundable security deposit upfront is a good way to protect yourself from damages, too.If you haven’t already, setting up a website for your property is a good idea.

Would it be a good idea to take a deposit to secure the deal until the rule clears?

The idea aspiring investors get mesmerized with is basically to start in real estate and somehow build a portfolio out of thin air.

Quote from @Jokari Trueheart: HI, almost 11 months ago I purchased 3 duplexes and I borrowed the funds from my personal residence which I took out a equity agreement for the down payment on the investment property, great idea at the time because I have 10 years to pay it off and theres no payment requirement, but , I learned more about the consequence that it takes a large chunk of my equity the longer I take to pay it back, so my goal was to refi cash out the investment property to pay it back but I don't think theres enough equity yet to pull the full $106k needed, I only borrowed $88k but with the equity percentage for one year i'm paying about $18k in equity on top of the amount I borrowed if I pay it off in year one, so I need this paid off ASAP before it increases more.

One out of the box idea that might be cool is to implement an educational feature similar to learning a new language on Duolingo.

I have never owned my own property, yet grew up in a family real-estate holding company and directly understand the power of real estate investing.Since 2020 ive seen homes double in price. 

Laying the FoundationWhen I started at PPR, I had no idea what a note was and knew nothing about real estate investing.
