We are in the process of purchasing a rental property and found signs of drywood termites during the WDI inspection. The Seller seems willing to treat the termites… which for drywood termites means tenting the structure (as I understand)… but my main concern is determining the extent of the damage. I assume the only way to do this is to start removing sheetrock where you see signs of WDI and keep going until you don't see anymore damage. But, is there a better and less destructive way to determine the extent of the damage? We are still interested in the house but I have to quantify the extent of the structural damage so I can negotiate properly with the Seller. Any advice would be appreciated!
