I'm an investor and property management company owner in central CT. 

In general, this is C or C- area.

@Shayvonne Chan recommend you connect with @Samuel Eddinger as he knows his stuff in your market!

My core investing philosophy is pretty simple, and has done very well across almost two decades and numerous cities:1) Invest in cities with population (and job) growth2) Invest in parts of the city where household income is near the median (or slightly below)3) Invest in properties that provide cash flow from day 1

I personally read 2 books about wholesaling that cost me under $100, which gave me a solid foundation.

I wish you the best in investing journey.

I would like to start using social media, in particular YouTube, to market my business but I know very little about it.

Unless you are confident in estimating the renovations needed, I would highly recommend getting a contractor's professional opinion of the rehab costs.

Even at that, all these years later I still have a lot of cash locked in properties. 

Once that's covered, you can go all-in on those fabulous renovations.Effective marketing plays a pivotal role in attracting tenants and increasing property appeal.
