In a recent house, we found:- Lots of ammunition (sold it in bulk for $500 to a gun collector from Facebook)- Baseball cards (sold 4 cards for total of $200 on eBay)- Large Buck knife collection (sold most of them for $600 on eBay, saved a few)- Several thousand comic books (book value probably $1000-3000, though we haven't sold them yet)-  About two dozen books from the 1800s, in very good condition (likely not worth much, but very cool, and there is one book that has a good story to go with it that might help me to meet Neil deGrasse Tyson)-  An air rifle from the 1870s. 

Now that I officially know about the mold, I may have to pay about $20K (2 estimates so far) to clean it up, taking it back to the studs in some places, pulling back the baseboards in others, then cleaning with sporicide and doing air scrubbing in order to get an official clean bill of health since i can't rent or sell without that, having officially established that I have mold.

I custom built my house and even after having an air tight contract, I had to fight with them (and give in a bit) to get a contract release so that I could convert my construction loan to a permanent loan.Would need to understand your situation and chronology to understand where you stand.Did you have a direct contract with each contractor?

In the end, we put in an entirely new central A/C and forced air heating system, all new pipes, new sump pump, and a lot of new electrical.In any event, despite being way over budget, I think the rehab came out pretty nicely…The exterior:(Before)(After)This laundry room space later became the breakfast nook and part of the kitchen.

If you're not setting aside that CapEx money youre going to be hurting when three of the air conditioners go out at the same time. 

Need heating and air 

I did not want to replace the tubs, and the refinished tub looked much better than before.If you are using it on a higher end rental or on your personal residence, you may have higher expectations.Please note that you should definitely have a lot of air circulation (ventilation) in the room - the smell/fumes are quite strong.
