Treatment and repairs can be extremely effective - - and restore the value of a property, in my opinion.
If you really love the home, then it is worth getting the treatments, and repairing any damage which may have been caused. If you are looking to protect your home and the value of it - - Fix it!
If you are looking at buying a home of which you are aware their has been a problem, or the potential of one, often times in the negotiations, a buyer can ask the seller for treatment to take place prior to the purchase and show receipts to that affect, or ask for a financial concession off the selling price or towards your closing costs in lieu of that repair, freeing up your own money to take care of the problem after your purchase. I do always opt for the second option, when working with Buyer Clients - - that puts them in charge and control over who performs the work, the cost, and most important the warranty for the work.
Shop around for treatments or treatment plans though because prices can vary greatly from what I have seen in my experience. Good luck and don't hesitate to contact me if I can help with any other advice.
Value is impacted in a few different ways. First of all there will be some buyers that will not purchase the home regardless of the extent of infestation and damage, therefore you have fewer buyers interested in the home. Secondly it depends on the extent of the damage if any and if it was repaired properly. Lastly there is an ongoing cost of treating the termites.
Termites are a part of the environment. Nothing to get excited about.
Termites, just like water intrusion, if left unabated, WILL effect the value of the home.
If structural damage is caused, and the roof line resembles a saddle,. you can start deducting value in $10,000 increments.
Annual treatment, and keeping wood off the roof, eliminated water sources, is the best way to protect your house from a saddle roof. There is no shortage of 1920 constructed frame homes that are still standing proudly here in Florida where termites, sand, torrential rain all combine to make home owning an adventure.
Don't sweat it. Sign up for annual treatment then follow your real passions to celebrate life.
Really, this depends on your buyer (or potential buyer.) Having the treatment done and being under contract with a pest mitigation company (with proof of contract in hand) is essential. Make sure to disclose the issue before any offers are submitted.
If you have substantial damage, repair the affected area(s). You should be fine.
Best of luck!
