In Oklahoma we have a ten day right of recission. Negotiate contract than inspect. Than if you have repairs maybe you can negotiate them.
we have a subject to inspect clause in Oklahoma which gives you ten days after contract to procure any inspections on put in writing any repairs which are needed to close or satisfy you. I would want to negotiate a price and agree than do inspections and if you have to you can negotiate price again after inspecctions if repairs are needed.
