Are these numbers too slim or am i just being a newbie baby?

[Casey Walker]

I have a three unit property under contract to purchase.  Just had the inspection and after estimating all the needed repairs i am getting cold feet.   

Current price 190,000

Repairs 40,000 to 60,000 depending how nice we make it and how much capx we do now vs down the road.  

After repair value is 300,000 and rents should be 3,000. Most properties work out to the 1% rule here.

Looking at the numbers we could make 50,000 still but that is only if nothing else goes wrong.  

Are these numbers too slim or am i just being a newbie baby?

Thanks
