Or would the funding for PML / HML dry up, therefore making it worse for us? 

Maybe I should've given a little more context to this situation which I think would address most of the concerns you brought up.My uncle owns a restaurant wholesale supply business that provides supplies (dry and wet) to a lot of restaurants in NY.

I have to clarify with the wholesaler if he is dry funding because an assignment may solve all of our problems.

The addition is roughly 600 SF and has been dried in already.

I'm not sure if there has been any dry cleaners next door many years ago but I don't see any around the block currently. 

I rarely use the actual stakes as I tend to put them on concrete or inside, but they attract a lot of ants and unlike the Terro liquid that goes on cardboard, it doesn't dry out nearly as quickly as the stake stations (I also add liquid Terro to the tops and four corners of the stake stations to attract more ants).The plastic bait stations are also decent but if they're on even a slight decline they empty out all over the ground.  

The dry land sits in the back and the only way to get to the dry land is through a 250 foot stretch of a neighboring property. 

This weekend I plan on getting the new section of roof felted so its dried in, and start tearing off the shingles on the old roofs.

second, your mold risk is much lower this time of year especially if its not heated now, but your gona have to dry it out before you rebuild,  having the demo done is a plus, but from what you describe, I would b a buyer in the $20's tops, i wouldnt touch $30K for my comfort level.  

It went well, but we never reshifted strategies here and that well dried up.
