I am no expert, so take this with a grain of salt. 

Remember, the notion of amassing wealth without investing is a dangerous myth perpetuated by self-proclaimed experts.

Quote from @Gerald Jarreau: Is there a government agency that will need to certify the rental as mold free?

He is an expert Poconos STR realtor and I believe would be a great resource for you. 

Contacted the warranty and as you mentioned they are experts in delays (nothing new here), but I also went ahead and contacted the electrician.Both later mentioned that they never received any call about this issue.

Condos are starting to get condemned, which means people are having to vacate units.I'm telling you right now, I'm a JD (not a practicing attorney) in Florida whose business is being an insurance expert for carriers, working with engineers. 

If he was truly a real company or an expert at this motivated seller craft, he wouldn't be offering you only 20 of them.Don't bother.

Quote from @Noel Parker: lol.. i am reading all your posts and you clearly are the experts(i say sarcastically!) 

I’ve come across options like the Institute of Real Estate Management (IREM), National Association of Residential Property Managers (NARPM), and Certified Property Manager (CPM) programs, but I’d love to hear opinions on which have been the most valuable in practice.Additionally, any recommendations for resources, books, tools, or online communities that have been helpful for day-to-day management would be appreciated!

I will be making $55-$60/h by the time I’m certified at 21/22.I am also looking into side hustles to increase my income such as flipping cars, reselling etc.As of right now I have around 8k saved, and 5k invested in stocks.Obviously I cannot buy a property with just a few grand right now, but basically I just want to ask for any advice or tips you would give to me or your younger self when you started.I usually listen to audio books on personal finance and business while working instead of music to further my knowledge.Any sort of advice is welcome, books, podcasts, methods to learn about.
