It’s not necessarily more difficult than market-rate rentals, just different.If you’re seriously considering this route, feel free to reach out.

If you pay off your mortgage (which is a good interest rate), you will likely burn through that cash flow as it is more accessible, AND that money isnt working for you anymore (unless you reinvested it).  

Do the numbers make sense with each and all interest rates? 

Quote from @Lillian Pintaro: I heard the rental rate wasn't doing that well in the Huntsville market, do to the new construction.

I think there were very very very few people who thought interest rates would go from 3 to 8% in about a year. 

$40,000 x 25%(assuming a 25% interest rate on credit cards) = $10,000This is more than the annual cash-flow that you are getting from the rental.I would look at a way to paying off the credit card debt asap.Look to see if you can take a HELOC on the investment property(likely difficult).If you can't you may want to consider selling the proprety.You will also feel a lot of relief of not having credit card debt hanging over you.What is the interest rate on the car loan?

And management is a LOT more intense, just turnover rates alone!

We put it on the market at $3M but never got the offers we wanted, it was during the holidays and when rates were skyrocketing.

I’ve had concerns about the crime rates so I’m trying to only buy in the better sides of town.

For the most part, due to interest rates, breaking the 1% cap rate still won't provide positive return after expenses.
