Obviously, when you're just starting out you don't want to make a load of expensive mistakes.

I have questioned if the middle wall is load bearing and what is involved with removing that wall.

Even if the tenant has insurance they will sue you anyway because LL's are loaded-I read that on the Internet so it must be true.I do not know what you can do about raising rent or giving her a notice of termination.

For 10 months, you've been carrying this property - a rather expensive paper weight. 

One of the big ones is the front loading of property taxes. 

,Your underlying question is simple-- do you want your tenants to know you loaded and have tons of extra money?

HVAC sizing is one of those things that really gets people worked up.The old rule of thumb was one ton per 400 SF.New houses that are well built with tight envelopes and lots of insulation can often hit one ton per 1,000 SF, even in cold climates.The right way to size it is to use a heat load calculation, a blower door test, and validate against your utility bills.A simple Manual J is often off, and I can tell you from experience that most contractors don't do them anyway.

If they were worth their weight, they would be walking you through this process and preventing you from having to ask for free advice from a bunch of strangers.That said, I would start the eviction process.

Reason being is that these frames are carrying half the load of the roof on each side of the frame.
