What do you think of these numbers?

[Kolby Wright]

SFR Purchase Price: $30k

Down Payment + Closing costs: $6500

Rehab: ~5k

Monthly Mortgage: $200

I assume insurance and property tax will run about $50 each per month.

Vacancy: 50/month

Repairs: 50/month

Total Expense: $400/monthly or 4800

I expect to rent for $600/month or $7200/ year.

Profit: ~2400/year or $200/ month.

2400/11,500= roughly 21% cash on cash return.

Did I calculate this right and are these numbers reasonable? Does it appear to be a good deal and return?

First time buying a property, what do you guys think? Thanks!
