Wanted your thoughts on my practice deal analysis

[Rishi Da]

Purchase Price: $420,000

Down Payment + Closing Costs: $98,000

Repair Cost: ~$50,000

ARV: $570,000

Forced Appreciation: $100,000

Deal: $420,000

Comp 1: $545,000

Comp 2: $620,000

Comp 3: $580,000

This was just a on-the-surface deal analysis and I was wondering if I was doing it correctly. Cashflow would be around -$500 a month, but that's manageable for me.
