How to Estimate your Home Building Costs
By Mark J. Donovan
||Estimating building costs can be a bit of a challenge, however if you are willing to do a little research and follow a few basic guidelines you can get a fairly accurate idea of your particular home building costs. There are numerous home building cost estimators on websites, including a few on HomeAdditionPlus.com, and they can provide some reasonably accurate estimates, however for more precise home building estimates you really need to look locally for obtaining your best estimates.
Start by understanding the real estate market conditions in your local area. In particular, find out what the average selling price is for new homes in your area. In addition, find out the cost of the typical building lot in your area.
Once you have these basic pieces of information you can then begin estimating building costs for your home construction project.
Using the sale price on a newly constructed home with similar quality and features that you want to achieve in your home construction project, first subtract the market cost of the land from the sale price of the new home.
|To obtain specific costs for each segment of your home construction project, e.g. framing, roofing, electric, plumbing, insulation, drywall, finish carpentry, etc. you will need to request for bids from the various contractors. I always suggest getting 2 to 3 bids for each segment of the home building project so that you can get some price comparisons for each segment of the project.
Once you have all the cost estimate bids from the various contractors you can select your preferred ones and then role them up to estimate your building costs.
The total cost of your new home construction project on a cost per square foot basis should be very similar to the cost per square foot you calculated earlier. If it is higher, then you may want to go back and press your contractors on why their particular cost estimates were so high.
|In some cases they may have legitimate reasons, and in other cases they maybe just trying to take advantage of your limited home construction project management experience.
