Even if they weren't, ANYTHING you can do to extend the life of the system is worth it, seeing as how a replacement will cost anywhere from $25K to $50K.

I also think that the business will compensate above and beyond whatever the legal terms extend.

The expense is worth it.https://www.homedepot.com/b/Search/N-5yc1vZbmgj/Ntk-Extended/Ntt-carbon+monoxide+alarm?

This may extend your closing date, but save you many headaches in the future, especially if your in a tenant friendly state.

That is because the rent-controlled apartment dwellers tend to stay in their cocoons for extended periods of time, thereby increasing demand for any available units.  

This will usually result in a extended vacancy.

I know sometime rehabs dont use materials that are suited for tenants.So keep that in mind as with tenants it may come with needs to fix things up when u want to sell again.You said that u had over extended with remodeling cost seems to me like you may have price the house too high?

So make sure you are not financially over extended. 

Further away it shouldn’t have much impact assuming the area is good from an economic standpoint and the environmental impact doesn’t extend off site (like a groundwater plume that extends for miles).

With that said, it may still not be too late as they often extend the time or a new countdown may come up.
