@Jay Wang I can only speak for the Raleigh market, but we've had a 15% appreciation Y-o-Y and I work with homeowners in the $600K-$1M price point who haven't slowed down their offering.

I can send you the listing agent’s name and number and if you would like to speak with him so you can also share that input.

While I am a huge fan of mini-splits, they still have not caught on so to speak as many do not even understand them. 

Not sure if any of them focus on subsidized renters, but you can speak with them about it.

If this deadline has not passed, you should be entitled to receive a refund of your EMD if you cancel (which can sometimes be your leverage for negotiation repairs or concessions*). 

Now, whether or not you LIKE that cash flow that's a different discussion but generally speaking if you want more cash flow you'll either have to increase your house price point or put more down...or sometimes even both.

The speakers do a much better job speaking than teaching.

The rules are changing fast, so it could make sense to speak with an attorney as to your options.

You should speak to an attorney rather than get legal advice from strangers on the internet.

Ask to speak with some of their current owners and current/former tenants.
