@Jonathan Yeh If you have a clean slate so to speak with a large lump sum, I would leverage the heck out of other people's money (and time, network, credit, etc.)
1. I would purchase a primary that I could househack. I like the idea of a 4-plex. If numbers make sense to use an FHA loan, then do so. If not, I would put down what I needed to remove the PMI. (If you use FHA lending, I would also move every 2 years to add another 4-plex to your portfolio). You could also do live-in flipping and trade up every 2 years to harvest the capital gains tax-free as well.
2. In tandem with number 1, I would set aside reserves and accelerate paydown of my consumer debt so I could qualify for the best financing.
3. Depending on how large the sum was, I would take ~$100K and start building a BRRRR or BRRRR-key portfolio to throw off income to eliminate my consumer debt, bolster my reserves and cover my expenses so I could hit financial independence and make work optional.
4. If I have funds over this (say ~$500K+), I would then invest in conservative syndications (MF, MHP, AL, SS) that preserve capital, kick off a monthly cashflow of 7-9%, aim to double my capital in 5 years, and gives me all of the tax benefits as a pass-through.
I would then use the income from #3 to invest more in #4, and the capital harvest from #4 to invest more in #4 until I'm financially free and go do something I passionately love!
