And if I continue to rent, rent will increase at least 100/mo each year.

Agree on a price slightly higher to account for market increase.

If that is the case I like my house to flow throughout, so I would use the same flooring and color you use in the other main areas of the house.

This fixes the rate, but also coverts the loan into an installment loan so your payments will increase and you will no longer be able to draw on the line of credit.

When I add appliances, AC units, new roof and a number of other upgrades I would expect to see an increase. 

Combine that with REOs and HUD with their ridiculous prices(many of them say no to assignments) and increased competition from more and more people entering wholesaling due to more people selling courses on wholesaling as if its such a goldmine and here you have the current market situation.

The increase is from $50/unit due to the "Clean water Atlanta" project, which mirrors the numbers you mentioned.They compare Atlanta to NY, and if my tenant's usage approached the average usage, I'll be paying almost as much as you.

Every deduction now takes away from my income, and income increases my taxes. 

Oh, between the two properties, rents were increased by $500.00/month.

These factors ultimately increased my mortgage payment thus reducing my cashflow to about $0/ month after accounting for vacancy, capex, PM fee, etc.
