General Contractors refusing to quote without them buying materials

[Svetlana Kazantseva]

Hi all! We have a really hard time finding a general contractor for our repair project in a buy & hold SFH in Kansas City, MO. We hired a property manager after purchasing the house and both contractors they sent in are "skeptical about providing a quote if they cannot use their own materials". In their experience "it has lead to a lot of headaches and delays with the project". We are out of state investors and were going to stick to David Green's advise of getting quotes without the materials for fair comparison + being able to select the material we want, put it on our credit cards. Do you think it's reasonable for contractors to refuse a quote without materials? Should we keep looking?
