I see, $1300 is very different than $600/$800 in rent. If accurate, that changes the calculations. Check your numbers as you increased the rent considerably.
You have big repairs. Keep the scope of work under control. I think you should define if this is a flip with a rental as a secondary exit a strategy, or if you are going to keep it as a buy and hold from the get-go.
Some very rough numbers may look like this, roof and gutters 10k, bath/floor 7k, kitchen 10k, paint patch 7k, floors 3k, windows 2.5k, hvac 7k (central air and furnace), electric trim, lights 1 k, doors $200a piece (door and hardware), water heater and plumbing (excluding bath and kitchen above) $1,800, driveway ($10/sf for concrete), ceiling at basement $800, demo $1000, electric, water, taxes, holding costs, etc . You may be looking at a $55,000 to $65,000 rehab depending on finishes, work you can do, and contractors prices.
Exterior work, landscaping, realtor fees, and closing costs are to be accounted for a flip.
Best of luck,
