I've been mainly going on the popular listing websites like trulia, zillow, realtor.com etc.

Using tools such as Motivator, AirDNA and Eliot and Me
These websites are very helpful, but they don’t make it very clear how they calculate their figures.

I did a quick scan, both those websites don't mention unit count.

Next, set up a FEIN, which you can get from the www.irs.gov website in a matter of a few minutes.  

Assessors website?

A lot of people say the online websites like Zillow and etc have incorrect property values?

I'm in San Diego and the SD parking Enforcement website addresses illegal parking in public areas, and vehicles abandoned on public or private property for 30 days, but if they're living in it for that time I wouldn't think it would be abandoned.

If you are looking for a property in SC in particular I’d highly encourage you to do some research on the tax assessors website for York county (if investing in this county) to know how to calculate the taxes prior to making offers and obtaining lending if going this route.Jared Wonders

So a google search led me to this website and I went on to read the BiggerPockets beginners guide to real estate investing and I was sold!!

When I asked the lender websites like bank rate are advertising 4.17%, I am being told that the websites like bankrate don't update in real time and there is a time lag..
