Depending on how much data is available in your county this can be pulled from the tax records automatically as well.

there is no substitue for a cma for a competent realtor,but all the sites you mention pull data from mls,county records,etc to give excellent info and as mentioned sometimes very accurate sometimes not ,the data is delayed so a realtor can be more accurate.nit is like getting real time stock data vs delayed or end of the day

Lucas is correct...HUD inspects and appraises homes they list.Because they have the data, and "local" talent doing the inspections, they know what it will cost to repair the problems and bring a house "up" to meet the minimum standards needed to qualify for one of their loans.

I can't defend my position with any great load of data or passion; it just made me feel safer.

Put your own name in and city to see if how accurate this amalgamation of public data can be! 

I've heard many tout the benefits of using a VA to handle many of the mundane: number crunching, data review and updating of spreadsheets, etc...So, how does one decide on a VA, what services do you use and other input you might have regarding the topic.thank you in advance.

Property tax data is usually in the form <Owner Last Name> <Owner First Name> <Owner Middle Initial> ...  

The data must be easy to access and manipulate, and interop (exports, data exchange) should work well.
