Two proposals can describe the same house and still leave you comparing different work. One might include kitchen hardware. Another might list a cabinet allowance without saying whether hardware comes out of it. The total is easy to find. The difference can take a little more reading.
Before you choose, give the unanswered questions their own page. You do not need to become a construction expert. You need both builders to explain the work they assumed.
Start with the same drawings
Write the date and revision of the floor plan beside each proposal. Check whether both show the same garage, covered patio and room layout. If you changed the island after one builder prepared a proposal, mark that difference before comparing the kitchen amounts.
Keep the drawings, specifications and proposal together. When a description says “per plan,” ask which plan it means. A clear answer gives you a common starting point for the next conversation.
Make a comparison sheet
Use five columns: the work item, what each proposal says, what remains open and who will answer. Start with the things that matter most to your home. Kitchen cabinetry, the driveway, utility connections and the covered patio might be useful first rows.
Copy the wording rather than filling in what you think it means. Mark a blank description as “not stated.” An unanswered item is a question, not proof that the builder has left it out.
Here is an illustrative example. Proposal A lists kitchen wall cabinets and installation. Proposal B lists a cabinetry allowance. Neither description tells you enough about the island, drawer fittings or handles.
Ask each builder to identify the cabinets included and explain how the missing details would be priced. Then update your sheet with the answer and its date. The point is to compare the same kitchen, rather than decide which short description sounds more complete.
Ask what an allowance covers
An allowance needs an explanation you can use when making selections. Ask what the stated amount covers, which quantities or products were assumed, and whether installation and other associated work are included.
Then ask what happens if your selection costs more or less. Who shows you the difference, when do you approve it, and where is that decision recorded? Ask the builder to explain the terms that apply to your proposal. Keep the written answer with the relevant selection.
Separate the house from the site questions
A floor plan does not show every question about the land. Put clearing, grading, driveway work and utility connections on separate rows when they apply to your project.
For the driveway, ask both builders which route, surface and endpoint they assumed. If you want a guest parking area, point to it on the sketch. For utilities, distinguish a provider's confirmed connection from a listing that simply says service is available.
If you are still gathering those answers, our checklist for building on your own lot can help you prepare the documents and questions. Keep an unresolved site item visible instead of hiding it inside a total that feels more settled than it is.
Check the decisions that come next
List the selections still open and ask when each needs to be made. If you are comparing two different windows or flooring options, record the actual product or specification being discussed. A photo can explain a look; it may not identify the product included.
Ask how a later change would be described and approved. Moving a wall or changing an island can affect more than one drawing. Find out how you would see the proposed scope, price and timing before deciding.
Leave with three clear notes
At the end of the conversation, write down the biggest difference between the proposals, the question still unanswered and the person taking the next step. Send the relevant marked-up page so everyone can refer to the same item.
You may still have choices to make. You will have a more useful comparison when each total sits beside a clear description of the work, the assumptions and the decisions still open.
