Please help confirm my 1st off-market flip #s in Denver, CO area

[Sheri Lowrance]

I have an off-market 2 bdrm/1 bath, 1085sf, no basement, no garage, single family home a friend told me about where the seller will sell the home for $100K cash. It is in Old Town Arvada, which is a very popular location with rising prices and rents around $2K for 2 bedrooms. Zillow shows the estimated value around $370K, which I'm confident is the minimal ARV. Home was built in 1952 and appears to have never been updated. It does have a recently new roof and sewer main line to the street. Other than that, home has NOT been maintained and is in very poor condition. With my uneducated look, it doesn't appear to have foundation issues. It will need an entire gut with new electrical, windows, plumbing, etc. The garage was converted to an extra room, so could make it into a 3rd bedroom (and additional square feet, which probably isn't in the 1086sf showed online).

 I've never done a gut rehab before, nor even a fix and flip (only a couple of minor rehab and hold).  Can someone please help me confirm my #'s and see what I may be missing or significantly estimating wrong?
