Compare the data and voila, appreciation rate for the last three years.

@Charlie MooreDo you mean data storage?

I I would request that data from the person sending you the tape!

Cons: 1) there is a learning curve that takes time; 2) employees required; 3) difficult debt markets (could be a pro for the creative investor); 4) limited market data and comp sets to aid in property review.

That said, I think people are busy and oftentimes post things quickly without thinking them through or showing the data.

Companies like Equifax and Capital One, who have enough money to pay for really good developers and IT security, have shown that they can't keep client data a secret.

I will talk to my local accountant tomorrow, and my long-distance accountant on Saturday, but want all the data I can get.Any advice welcome. 

We take a really data driven approach to the site selection, concentrating only on centerpoints that analytically meet the requirements our operators are looking for, and then we go in and start to match that analytical requirement with the desirable physical attributes we look for.  

We are building a software that tracks data.

I'm happy to help in any way possible with the skillset I have in exchange (I'm a full stack developer, so I love focusing on data!).
