Hi, I was informed by my listing agent who said I can "discriminate" meaning I can ignore, reject, decline app compared to in her capacity she needs to take every call/messages and respond.

And that house, is 1.5 years on market, and its in an area with other houses that are in the $5-15 million range.So I do find it hard that the agent who looked at it is determining based on comparable sales that the property is $600k, could get to $2 million.

I'd get another realtor in to also do a market comparison and compare what the two say.

This can help you objectively compare different markets and make a more informed decision.Also, networking with local real estate professionals or joining investor groups in your target markets can provide valuable insights and help you gain a better understanding of each market's nuances.Would you like more specific insights into the Oklahoma City/Tulsa real estate market?

I just bought my first investment property near Scranton. it was a pretty good deal compared to the prices I normally see in jersey.

And this was the late 90's so there were a lot less resources readily available, as compared to today. 

We have a low interest rate compared to today, a bunch of equity in the house, would be a reasonable cost for the investment since I’d still own the other half . 

Cash offers with low to no contingencies are typically going to be more appealing to sellers since there are less "hoops" to jump through compared to traditional financing.

Those who are pulling in 80k/year compared to the 50k - what is different?

Then look on VRBO and Airbnb and guesstimate rates and occupancy for your area on comparable properties.Put all this in a spreadsheet and let it do the math.
