@Dan CawleyGreat questions Dan...IMHO when beginning you should concentrate on a single group.

If you're not interested in marketing you can just concentrate on doing Real Estate.

just because there is a significant investor concentration, doesn't mean there is no financing for those properties; it's just more expensive and requires about 30% down. 

Concentrating on my 9-5 job, I made enough money to begin investing in SFH's in the Florida market and low and behold a few short years later I have 6 rental properties that cash flow nicely!

Don't compare yourself to someone else, compare yourself to yourself and just concentrate on making yourself the best you can be.

I think you should concentrate your efforts on finding a new place to live.

I need to find my niche, so that I can concentrate on getting mentors in that area.

Section 8 properties can be lucrative for a stable income, particularly in areas with a high concentration of low-income households.

I've been looking into properties in Cleveland, both SFR and MFR and it seems like the majority of the value add deals that are available are concentrated in the SFR sector.

I've put money into a self-storage fund, a manufactured housing fund, multi/commercial REITs (through realtymogul.com) and even looking into a cannabis dispensary fund. 6-8% monthly dividend and 16-20% IRR> Feels good to me, but hard to know for sure.
