Thought I'd add some data here for May. 

Hi Jasraj, I completely understand where you are coming from because my Data analytic brain wouldn't budge without some sort of food(read data).

@Tommy AdeoyeTry going to your county clerks office and looking up “lis pendes” in their real estate data base.

I am really trying to "follow the data" as much as I can. 

Or you could just not proceed with it right now, and if you think it has little value as-is, will sit idle for a while, could drop in value in the next few months/year, etc. then you could possibly negotiate a better deal down the road. 

Now, in regards to the practice of restricting the data being shown because you as a PM is concern that the owner might get worried because of the data readings, calling you in panic and wasting your time.

It has tripled in value, this was my first property, It's off 5th street and Pico, I will keep it forever.

Real data can often times prove lower risk meaning lower premium.

The factor is that most property, even those purchased at the wrong time, and for too much money, tends to increase in value overtime.

So how does one go about finding comps without the latest data?
