1st Property Flip. Inexperience and Looking for Guidance. TY.

[Michael Menard]

Hello all, 

I've done some due diligence on the site but when trying to find the right information when there is so much and then when I do and the fact that it's usually an individual or a small group of individual's opinion makes it difficult to take the first step into the "game". I figured that I'd start a discussion to funnel people with ideas about my specific situation. 

This would be me and my family's first time flipping a house. I'm only looking to spend $40,000 at the most and am looking at properties in Jacksonville, FL. I've been looking at properties around the price of $15,000-20,000.

They are in horrible neighborhoods but I feel like that is the safest way to start out as far as debt. Please let me know what you think. Again, I may have no idea what I'm talking about, don't

I've made an Excel worksheet and am trying to become fully aware of where I will be and how to get a certain goal out of it. 

Let me know if you think I'm going at this totally wrong or if you have any pointers after reading my perspective. 

I have 4 scenarios in the Excel sheet. 

Scenario 1 (20%, Ins, Low)

Scenario 2 (5%, Ins, Low)

Scenario 3 (20%, Ins, High

Scenario 4 (5%, Ins, High)

 20% being 20% down payment, Insurance being ~$100 to have the house insured, Low being low repair fee (~$5000) and High being high repair fee ($10,000) I have these 4 scenarios to figure initial investment and then have the variable/monthly in the columns following. 

(These repair figures are just estimates based on the neighborhood and eyeing solely photos, which I know is not accurate but that's why I'm trying to give it four scenarios and then if it goes above the High fixing price, then move to another property or adjust the numbers)

The two costs that I know of now are insurance and mortgage. Is there anything else you would add to this for me to get a better, more realistic understanding?
