I threw dozens of questions at both of them that they answered easily.  

Is realtor.com, using the "recently sold" filter a good source?

They won't look like new floors, but they will look nice and if they get some damage (within reason) you can more easily deal with it yourself.

You should have in your expenses / P&L a line item for R&M (Repair and Maintenance -- basically toilets fill valve, A/C filters, dishwasher repair, etc.) and another for CapEx (Capital Expenditures - New Roof, New Water Heater, New Carpet, etc. 

That could easily produce $1K net monthly cashflow for you plus the other benefits of real estate: appreciation, loan paydown (by tenant), tax benefits (paper losses), and inflation profiting (inflation erodes the debt).

And "deal" varries per zip/area.You might read my paper a file I linked off my BP profile, how to buy a bullet proof rental portfolio, to help you center your buying filter on what type of tenant you want to serve? 

The asking price is 2.1M and each house will easily go for between 1.8-2M.

If they are professional, they can explain this quickly and easily.

Depending on your state, there are disclosures and other processes that are supposed to happen, but someone familiar with the process can navigate it without an agent fairly easily.
