Vetting through contractors
What are the most critical questions to ask a new contractor when you are going through the vetting process? For example let's say I'm preparing to do my first flip but I do not have a specific property yet and I'm just interviewing contractors to have my ducks in a row so I know who I will use once I secure a deal. What questions and/or due diligence should I be doing? The obvious things are making sure they are licensed and insured, asking how long they have been a GC in the area, asking for before and after pictures of previous jobs and asking for references of previous clients. Is there anything else particularly I should ask or be on the lookout for? Thanks BP!
