[RealEstate] Add a feature for buyers to negotiate repairs as part of the contract

So we're under contract for $215k on a place that was sitting for around two months. Had some major issues come up during inspection - furnace was shot and actually creating a carbon monoxide hazard with the water heater venting. Pretty scary stuff After we sent over the inspection report, sellers got quotes and decided to replace both units without really discussing it with us first. Now they're asking us to sign an addendum bumping the price up to $220k since they did the work. We never agreed to pay extra if they chose to make repairs My agent checked with their legal team and confirmed the sellers can't just walk away because we won't pay more than our contracted price. We're supposed to close mid-February and appraisal is already in motion I'm getting a bit anxious though - could they find some way to torpedo this deal? I've got money tied up in earnest money, inspection, and appraisal costs. Just wondering if anyone's dealt with sellers trying to pull something like this before The whole situation feels pretty sketchy to me. They made the choice to do repairs instead of negotiating, and now want us to foot the bill retroactively. Seems like they're testing how far they can push things
