I've found it helpful to get a general sense of different neighborhoods/suburbs and have found it pretty accurate.

Know how much you can borrow and have accurate estimates for rents. 

It was out of state and with as small as it was I took a gamble and did not step foot in it until i owned it, but I had the local realtor go thru and do a video and a basic eye ball inspection and felt confident.

Sajan,There isn't enough info here for anyone to give you accurate advice.

Hi guys, Would any one know a good remodeling designer, that can measure a sitting building accurately, provide CAD design?

You can gamble on appreciation, but you aren't going to pay your bills or earn a good ROI on Milwaukee properties at that price point.  

BTW - I see you also noted the "Lawndale neighborhood" as located in 60608, which actually does include a sliver of Douglas Park and Little Village, however those are FAR FAR differentiated from the majority of 60608 which is Pilsen - a neighborhood which substantially skews your averages upward in value potential and downward in crime.60632:  Lumping 53rd/Kolin with 36th/California couldn't be further from anything remotely accurate.60612: Rough parts of Garfield Park coupled with Tri-Taylor...oh man.

The information is seldom accurate so much so that consumers are starting to post about the accuracy of these sites or the lack thereof.

Account Closed I was surprised about how accurate you were on your info, good job.  

Yes, it will take longer, but if you're seriously looking at properties you need to run very accurate cash flow projections.
