First time REI in Fresno market

Hi, I am completely new to real estate investing and am starting to look at single family homes in Fresno, CA. Many of the homes I am looking for range about $119,000 to $130,000 for 2 or 3 bedroom/1bath homes. Anyone have advice on cash flow and if properties around this size & price would cash flow well? I am running numbers to the best of my current knowledge and it seems I may get around $750-$1,000 per month depending on the location and condition of the home (with $750-$850 being average). Monthly payment is estimated to range from $675-$750 on different properties with an estimated 5.125% interest rate. I feel that it may not cash flow well since it seems like my payment is quite higher than I initially expected.

Example: 

2 bed 1 bath in 93728 

Asking price $125,000

Closing costs estimated: $7,200-$8000 (includes interest, insurance, and taxes for 1 year)

20% down payment

Total due upon close: $27,200-$28000

Thanks for any advice or feedback!
