Comparing Pricing of Tenders against other Builders

When comparing pricing of estimates or tenders between builders its important to do a like for like comparison as a lot will leave out things that you will need or things that you will likely upgrade eg. Kitchen. What worked for me was filling out the following table and filling out the estimated values.

In many cases the items in the site costs are included in the base price and other features may be included in promotional packages so you might not need to add these values individually. This is why its important to not just compare base prices against each other as its very misleading.

The estimated costs here are averages I found across multiple builders and these wont all be charged by all of them and the amounts can be less or more.
