The tenant has been there for quite a few years and has broken so many aspects of their lease I lost count.

You may be able to receive $1400 a month depending on upgrades.

It's doesn't really matter how it's broken down in actual structures.

Once you acquire, you start your rehab, let's say you upgrade the kitchen and it costs you $15k -- you submit your receipts to the lender to show you paid $15k for the kitchen, and they send someone out to verify the kitchen is done.

Finding an honest property manager to look after it would be the sort of experiment in futility the Nazis devised to see how thoroughly minds could be broken.

Because, as you might imagine, a tenant turnover will cost considerably more than $225, but as @Thomas S. mentioned, the actual insulation bill for an attic will be considerably more than $225.Go to www.homewyse.com (I love this website by the way), select "Installation", then, "insulate attic" and see that their rough estimate range is from $1.59 to $3.08 psf (labor and materials), but then it depends on whether they are insulation batts, or blown in type insulation.In any case, if the existing attic insulation is inadequate, then maybe this "upgrade" might be warranted, regardless of how long the tenant has been there. 

Broken hand rails, missing plate covers.

Around here the gas are more expensive. and the gas company here seems to try everything they can to get you to replace almost every time they come and  want you to upgrade to the latest codes. 

Yeah, the housing is not up to the standards that you or I would live in, but you always have two choices:  Upgrade and charge more, or don't and charge less.
