Not all price ranges  make good cash flowing investments. 

Given that I'll be house hacking my realtor created a list that focused on duplexes but giving the cost of CapEx I can't really see duplexes within my price range, (below $115k), making enough rental income to sustain and cash flow positive long term.

Your rent will need to be in the range of 1% of the full market value of the home  ( or better) not 1% of the mortggae value if you want to see any return on your equity.If you can not get a minimum of 2K rent per month it would be wiser to sell the property.SFHs purchased as a personal home are very rarely a worth while investment as a rental property.

For what it’s worth, over the past couple years, my increases ranged from 3% to 8%. 

If you're working the sub 50k range, you're going to have a ton of deferred maintenance, problem tenants, and most likely a bunch of move-outs or evictions if and when you get the properties. 

This ranges depending on the loan/property, but assume another $150-$200 a month.

I would just like to purchase homes that are around the $120,000 range and in non flood zones to keep our costs down.Thank you

However, I may be in a unique situation.

If you have a price range and plenty of downpayment you can look almost anywhere.
