Even if there are some local newbies or even well experienced individuals who may share similar inquires. 

- Taxes: If I invest as an individual, would I get the tax benefits of investing directly in RE (owning a SFH for e.g.) or are the dividends taxed as ordinary income?

Usually there is not a universally true right and wrong investment decision that applies the same to every individual.

Super low compared to individual tax returns (Form 1040).

I honestly wouldn't waste my time with individual investors.

So I have been getting calls by different companies/individuals.

They can help you crunch the numbers and make an informed decision based on your individual financial goals.Best of luck with your new investment property!

I would prefer to go with a established company (rather than an individual hustling on the side) with streamlined processes, transparent online accounting, and a long and strong track record. 

I'm simply planning to buy the homes in working class, relatively safe areas, fix them up well and furnish them and rent the rooms individually to make minimum 1.5-1.7 times higher than normal rents by including their utilities.

Definitely you cannot do this in a taxable account purchasing individual stocks.Certainly Roth accounts have no gains tax regardless if used to purchase stocks or RE.
