Cash flow vs equity?

[Shane Craig]

I'm writing this post to get everyones opinions on a deal I'm considering.

All of my previous deals I have purchased were for cashflow. This deal I'm considering has minimal cashflow( 1K-2K a month) but has a high equity potential (500K). 

Deal break down: 17 houses ( 3bedrooms/ 1 baths) that have been maintained very well by the same owners all within in a mile radius. Each house rents for $750-800 a month. The seller will sell the homes for $1,275,000( $75,000 a house). I'm a realtor and I know the market well each house is worth 105-110K. Also the seller has sold two homes for $105K each over the last two years. 

This will be my biggest purchase and I'm worried on the low cash flow. 

What are your opinions on cash flow vs equity ?
