The basement barely has vents, all hopper windows are kept closed during the day and it can’t really get any fresh air coming from outside.

Each entity at the bare minimum needs a checking and savings account so you don't commingle funds.

Built in 2017 and barely lived in, so still feels like new.

Also, $3k to furnish and apartment is a pretty bare bones budget.

@Josh Darley a bare minimum of “your responsibility to turn on the gas” and “ here is the number for the gas company” would have prevented this.Why wouldn’t you do this?

I've barely just started researching and studying REI only a month ago now. 

Tampa Bay has only seen increasing demand for houses with supply that can barely keep up.

Even with the proper vetting - you can still get a bad tenant I don't use a PM and vet everyone myself - I find that if it not your home then there is less vested interested into putting extra effort into booking someone - regardless it's your home so you bare the brunt unless there is an agreement that say otherwise.

Market rent is probably $1,350-$1,400 so would still barely cash flow. 

You could start my emailing them and saying you want out...and if that doesn't work...email their managing broker and say you want out...they barely did anything for you so not much invested...One would hope it would work right there, but if it doesn't, then its up to you whether to roll the dice and wonder if this other agent will decide to take you to court over it.
