If they're good tenants you can always try a compromise of 9 months, which is April 1st. 

I'm sure there's some compromising/negotiating that comes with it though.

(The assessment I got from both the home and sewer inspector is that they don't think this flood out compromised the foundation.)3.

@Kaneisha Forrest Also if the fire got hot enough your slab could be compromised.

As for what you can do, without having read your contract this is just a guess, but perhaps you could ask the seller for a partial credit towards the purchase of a new heat pump as a compromise (will probably say no since it’s “as is” and the current one is still working but might not hurt to ask), or walk and lose your deposit (unless there’s some other contingency still in effect). 

If you like them, see if you can find a compromise where you increase them significantly but still slightly below market so they're still living at a more affordable rate than they'd find elsewhere. 

The issue that arises with K&T is where the integrity of the wires are compromised. 

If you are firm and strong up front, it sets the standard which will not be compromised (late fees, repairs, etc)Best of luck!

Infusion- I would love to, but the rent does not justify the asking price, unless I compromise on my target returns.Thanks Laura for the suggestion.

If the safety of my life feels compromised I'm taking the shot and I'll worry about the media when I'm safe.
