I bought an almost rent-ready triplex sight unseen in September and got it fully rented within 60 days of closing. 

The chances of you taking $150,000 and turning it into enough passive income to be able to live are as likely as you taking $150,000 and putting it in the stock market and living off the principle. 

Those losses can be substantial, by the way within an HVAC system-Again I doubt these technologies would hold up under scrutiny within a court of law because all it takes is one person with even a basic grasp of principles of engineering and you’d find an easy 10+% delta in these systems’ measuring abilities.

I am new to REI and still trying to understand the REI principles by reading, listening to podcasts and fiddling with RE calculators.

I plan to pull my principle investment sometime soon and keep a balance of it. 

Based on personal experience, I would add assuring the lender is specifically authorized to perform an on-sight property inspection, at the lender's discretion / convenience. 

I was in a similar spot with a high paying W2 when I first started investing in real estate.I took the principles from BRRRR and Long Distance Real Estate Investing from David Greene's books and went at it.

For instance, a worksheet calculator that you can depend on for accurate rehab numbers, a coach or mentor that has experience wholesaling whose brain you can pick, a curious, principled solution-based mindset, willingness to find sellers that are NOT on the market, and for good measure -- steal underpants!

I buy foreclosures but never sight unseen.
