(ah, so paid answering service given the script "this is zillow" I use one as well for my business accept that the service pretends they are in my office referring the call to me instead of pretending to work for a totally different company in a bid to trick the caller). 

Pretend you have girl scout cookies to sell.

You can use tax records to look up the owner of a property and confirm that the person on the phone owns it (however they can lie about their name.)Its not to late to have a friend call and pretend to be a different landlord and ask these questions as well.

@Philip Amundson Admittedly I would say most properties do need some small repairs and/or updating to maximize rent so I'm not going to pretend you will be able to find a 100% turn key property, however if you can find one, then it will preserve your cash and set you up better for #2.  

Let’s not pretend that we don’t know what affordable for a neighborhood.

Your property is worth $75,000 so let's pretend they give you a down payment of 5% which is $3,750 and probably more than they can afford.

The Cash Flow is ridiculous.Over time, you get to understand that Cash Flow is something that only stays the same if you invested in something that is designed to do so like a Coupon Bond.Because I calculate the FUTURE Cash Flows out 10 years, I fully understand the true return of the Investments and how much cash flow I will achieve.The other thing to take into consideration is the Mortgage Balance reduction.If your investment is at break even but your Mortgage is a fixed rate, then one day, when that Mortgage goes away, your Cash Flow increases tremendously.When you take into account a 30 year projection of your Investment Cash Flows, you realize just how wealthy you can get by buying for FUTURE Cash Flow as opposed to Cash Flow NOW.It's really not RIGHT to pretend that the Cash flow you receive at the purchase is going to be the same throughout the holding period of the investment.

I do have a concern about showing up to an open house and pretending to be interested, but in reality, I am at the open house to practice my analytical skills.

I have the same anxiety towards risk that I think you're having and I've noticed that sometimes it helps to step out of yourself when analyzing a deal and pretend that you are coaching either a new investor or your past self through the process.

If you want to pretend to have morality, then go buy a high end property in the snooty portions of your area and leave the low income areas alone.
