I grew up in Harwood Heights , a small town bordered by Chicago on three sides. I now live in Elmwood park ,IL.   There is actually a book about Harwood Heights called " Island Within a City"  It is very interesting to see the changes documented from the days of farms to present. neat stuff.
 In home inspection , history is my friend, any glimpse into the past helps be discern the present, and sometimes guage the future.
 HARWOOD HEIGHTS WAS FOUNDED IN 1947
 ELMWOOD PARK, I BELIEVE WAS AROUND 1920 s

The House i live in right now was built in 1927-  A square shaped MILLs BUNGALOW.
Many homes in the area are similar, i've gained a lot of experience in these types of homes.
