Buying HUD homes was just a better fit for me than contacting individual sellers. 

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.

Make Assumptions: Consider possible reasons like a tired landlord, property in rough condition, or a bad location.Confirm Assumptions: Ask the seller and consult local experts (property managers and real estate agents).Update Assumptions: Incorporate the new information.Adjust Analysis: Integrate the updated information into your analysis.

@Neal Collins You're right that the new Podio (Citrix) business model doesn't help individual investors but if you've used GlobiFlow previously you should be able to continue using GlobiFlow using their old pricing scheme.

Like Alicia mentioned, typically not advertised you will want to get to know the individuals.
