good afternoon pirom,
I'd say it depends on the situation. I just did the initial viewing of a property yesterday with a contractor I know. Im an ac tech so I've got personal relationships with a lot of ppl in the industry.
It was much easier to show up for the initial walk through with my gc and re agent in tow that way I kill multiple birds with one stone. This may not apply to everyone however.
My gc contacted me today with a verbal bid......which I told him was too high, so he's gonna get back to me later with a revised/lower written bid that I can send to my Hml.
It depends on ur situation, the ppl u know, the amount of time u have at ur disposal (if it's a hot market u might lose the deal waiting for ur contractors to get u a bid).
Sometimes u just don't have time to wait for a written bid by a gc much less getting multiple bids from a few different gcs. It's important to learn how to estimate repair costs in ur market.
Regards,
