I do think it’s wise to have an exterminator come and seal any entry holes and place environmentally friendly traps to handle the problem quickly.

You need to make sure the board is reserving enough money to maintain common elements.

Which means there may be some elements of a distressed property.

Sourcing insurance and handling claims Legal suits such as ADA, slip and fall, environmental, etc. 

You need an environmental testing company (or at least someone who knows more about it) to test the house.

@Bing Lin, well that does add a little element of complexity that probably needs some discussion outside of forum. 

When we bought the house we are living in there was a 2,000 gallon fuel oil tank buried in the front of the house.It had been disconnected from the furnace when the furnace was switched over to propane, but tank was never removed.We found out from the state environmental agency that the tank needed to be inspected before anything could be done.

They wanted nothing to do with it due to the environmental risks and even said they would specifically exclude that from any lending. 

So, if the parties negotiate with each other, it is always an element of negotiations to say to the other party something along the lines of, "You might be right in what you are claiming that you owe me only $XX, but you will have to hire a lawyer to find out, so save the legal fees and pay me $XX plus $YY, and it will still be cheaper than paying the lawyers."
