For real estate investments with irregular cash flows, XIRR is generally preferred for its accuracy in measuring the true rate of return.

My friend gave me a list of addresses and I was able to track down the homeowner age pretty systematically (and with a high degree of accuracy).

Lending short term must be brutal in tax reporting, accuracy, fed and state dollars.  30%? 

I was browsing zillow/trulia/realtrac and see cool heat maps, but also hear people mention how they are way out to lunch on pricing and accuracy. 

Have not utilized realtor.com, Trulia, or Redfin as much as I want to, it's just a lot of data to sift through to try to pinpoint accuracy between all the platforms.

If I were certain of the accuracy of my crystal ball, I should sell now, not pay any capital gains, and sit on cash.  

To do so is to favor persuasiveness over accuracy, and to sacrifice truth for the sake of image."

You're worried about the accuracy of your projections.

I've also heard from a lot of other people that the Zestimate can be pretty far off sometimes, but for the rental prices I found this handy page (https://www.zillow.com/howto/DataCoverageRentZesti...) from Zillow that gives their own analysis on the Zestimate accuracy for a given city.
