Do the same thing with several neighborhoods and you build yourself a wealth of data.

. $39.99 a month or $59.99 if you add their excellent foreclosure data.

Does anyone have a Go-To source  or two for market specific , economic, employment, and demographic data?

Until I take my next step in REI and the majority of my business is comprised solely of assigning contracts to other private investors; I only want to be thought of or considered to be the number one wholesaler; at least in one way or another to every quality investor/professional that I have the privilege of I coming acrossI will always need as long as I am a real estate investor; all of the tricks, tools, & trades I learn through becoming a tremendous wholesalerI want every aspect of my lead generation, my property evaluations, my deal analysis, my renovation budgets (determinations, estimates, & timelines) the complete all in requirements in both time and holding cost spent from start to finish, establishing ARV’s, and of course nothing less than 100% picture perfect all-inclusive, data thorough, as easy to say yay or nay on in moment style property breakdown presentations!

@Heather Ippolito  if your taking the data from the MLS listing they are listing the annual tax's not monthly  .. what you do need to figure out tho is if the tax's are low because of owner occ status and will they rise when they are turned into rentals.In many states owner occ's get about a 50% discount compared to investors.. they get it through their homeowner exemption...

Most government agencies that keep this data are online and all have phone numbers. 

Granted, I don't have an adequate sample size, but the data tells me that I need to be willing to take the risk with the right wholesalers.

Sorry Molly, I don't know Baltimore at all- I am sure the local BP members will be able to give some direction.Meanwhile a place to start is the City Data website here.

Whereas a SB has to do their own market research for their product, there is ample market data for real estate in any market.

It is wonderful when you can gather info from a Realtor that knows the area really well - but supplementing that information with your own data is important.
