Getting cold feet... please help run my numbers

[Gabriella Borukhov]

I finally decided to invest in a fix and flip. Everything was making sense until I had a bunch of people around me tell me it's a huge risk. Now I'm so scared because I don't want to lose money and have a bad experience. It is my first flip and it is quite a "bigger" flip but the numbers made sense to me and wanted to know what some of you experienced investors think. 

Some details about the property. It is about 1900 sq ft. It is located In Florida.  Owner died and house has been vacant ever since. There was a probate. I did get a inspection done. Roof was done 10 years ago but there were some leaks identified so inspector recommended that I change the roof. It's on a block lot, no foundation issues were identified. HVAC is updated. Plumbing looks good as well. (Water ran for about 6 minutes). Electricity is good as well. Only issues that we have identified that we need to fix are cosmetics. Completely renovate the kitchen, 2 small size bathrooms, floors all over, "freshen up the windows" (windows were pretty old but contractor said we might not need to change them), cut off tree branches on top of the roof, add a walkway in the front. There was some termite damage on the fascia as well. Also, rodent droppings were detected.  

Home price is $369,000 

Rehab given is $80,000 

Down payment is $44,900 

Loan amount that I will owe back is $404,100 

Loan is for 6 months 

Holding cost for full 6 months is ($3500*6) = 21,000

Closing cost = 19,553

ARV = 575000 (my agent said $600,000 but I am doing 575,000 to be conservation, with the way the market is going I do question if I should estimate it lower)

With my math, using the full rehab loan and full 6 months with selling costs included, I estimate around a $53,000 profit. 

If I finish and sell faster, even better. 

This is definitely a lot to take on for a first time flip but I did put $10,000 earnest money down already and don't want to lose that. With all this information about the home, do you think there is enough of a profit margin to work with? It has been vacant for a couple years, do you think that there might be additional problems that will skew my numbers in a large way? Is 80k enough for a renovation this size ? My biggest fear is that there may be a huge issues that arises that prevents me from being able to sell my house. It could just be fear talking. Also, my backup plan may be to do a cash out refinance and leave some cash in the house but not 100% sure what the best option is yet. I would greatly appreciate advice and opinions. Would these numbers make sense to you and is there anything that I may be missing?
