This was within 10 days. 2 weeks later and the buyers messaged and said it was still leaking.

As a buyer, you're less likely to get the terms you want, you may pay more for a house than it's actual value, and you may lose some of the offers that would have won.Buy now, refinance later (if that makes sense for you).

One of the issues is that the floors were replaced as part of the rental in 2022, but months later they began to feel soft.

Some expenses will come later than expected, some earlier.

Additionally, the property I have for sale is located in the 48205 zip code, which I later found out is considered a "red zone."

Posting notice that you are attempting to contact them (or at least sending certified mail) will at least show that you are making an effort if the tenant would later take you to court over unfulfilled repairs. 

And the smaller areas in the south didn't take a dive for a few years later?  

Later, we stripped off the old patterned wallpaper inside the house and saw that the walls were covered in water stains.

I will be looking for a mortgage broker no later than tomorrow.

So we would essentially need to move all of our belongings out and then back in a year later.2.
