1st BRRRR - a good deal?

[Craig Hansen]

I am looking at investing in my first BRRRR. My question is on monthly cash flow. Here are the numbers:

Purchase - $70K

Rehab  - $50K

ARV - $180K

Cash out refinance - will get 100% of my investment back or pocket up to $15K

Problem - I am estimating that my monthly cash flow will be about $100 a month. My other properties cash flow +$500 a month. I am worried about the low monthly cash flow, but understand this will grow over the years. 

Is this a good deal? What are others doing about cash flow on BRRRRs
