Not the original commenter, but my dad is a contractor in central Jersey and I do all of his contracts and invoicing. He’s been booked solid throughout COVID and his only issues have been increased cost and availability of materials. I know for some bathroom and exterior jobs he’s had to wait longer than usual for supplies to come in; same goes for appliances. He’s been able to keep his help and subcontracting positions filled, too. He ends up encountering some of those “ghosted” customers/homeowners so I think the bigger issue in that regard is trusting your contractor and getting multiple bids. Good luck in your house hunt! I recently moved back to the area after nearly a decade in the PNW…there’s nowhere like central Jersey!
