A multi-trade renovation involves more moving parts than a single-specialty job, so the more upfront detail your post includes, the more accurate the bids that come back. A strong post specifies:
- Full scope: every trade involved (framing, electrical, plumbing, finishes) rather than just the headline item
- Current condition and age of the space: older homes often surface issues mid-project that affect cost
- Timeline: your target start date and how much flexibility you have
- Budget range: even a rough number helps contractors self-qualify for the scope you're describing
- Permit status: whether permits are already pulled, or the contractor needs to handle that
- Photos: help a contractor gauge scope before a site visit
Posting this level of detail once, rather than repeating it on separate calls to each contractor, is the main advantage of collecting bids through a single request rather than contacting contractors one at a time.
