Curiously, I thought about the following exist strategies before buying in North Center.
If you need the cash, sell. If so, I would sell it by owner or use a low cost brokerage like Redfin. We bought our house from a sign on the front lawn without agents.
Recall you paid 50% of the original commission, the fee is an intrinsic part of the purchase value and not paid by the seller, as they say. I would try to lower the overall transaction costs somehow.
If you don't need the cash, buy yourself time to figure it out. You are also making money in amortization and tax shelter to soften the negative cash flow. You could look into hiring an AirBnB management company or set up a corporate rental for a few years. You will make more money than renting the unit.
You could also partner with a developer and flip it. Although, at $800K purchase you will need a +- 2M rehab. Talk to a developer in the area, look at the high flips in the area or deconversions, call the agent and get the developer's name. They may give you a cash offer.
Good luck,
Frank
Update: I just notice you didn't put 20% down, so you will always have to pay out of pocket. I would be more inclined to keep it as a corporate rental or Airbnb for a while in that case.
