With the 2010 Census data available, there is good recent data on employment and population figures and trends.

There are any number of reasons why they may be different.Some counties have past sales available on line.Some title companies will make this data available.If nothing else, look at comps (not zestimates) on zillow.Best is to get access to the MLS either by working with an agent or becoming one.Very best is to learn your farm area intimately.

hi fellow investors.Pls share any experience You got with rental properties in north Philly.Still can't figure out how to treat data about crime and general low income and quality of living there.

I have a team manager, personal assistant, contract manager, three dedicated buyers agents (a fourth starting the 1st) an a couple part time data entry people/property inspectors.It does help giving leads to them and I make money off their own deals as well.

No more needing to copy paste or data entry into excel. 

They use data provided by the other three and develop the scoring model and algorithms used by each of the three credit reporting agencies.

Could you remotely access the data via internet, similar to an NVR? 

That said, it is possible to make adjustments on the sales comparison approach from data extracted from the income approach and the reverse holds true as well.As an example, let's say there weren't enough data to show what buyers would be willing to pay for a 3 car garage house versus a 2 car garage house (in this example assume everything else is identical).

I assume that your paper needs to include tons of statically data, graphs, parameters, etc.

Example could you take data from census like housing starts and building permits, existing home sales, sales tax movements, housing market index, ect. and map it out like stock charts do, then use something similar to technical analysis as a predictor?
