It is always difficult to estimate home renovation costs since it is a flexible number, depending on various different factors. Every remodeling project is unique, and costs vary depending on your budget, tastes, and priorities. According to Better Homes and Gardens, in general, materials will account for 80 percent of your budget, while labor costs represent the last 20 percent.

With products representing such a large percentage of the budget, you can help control costs by choosing the level of products you will purchase. When deciding where to scrimp and splurge, consider how you will use your new rehab and how long you will own the house. If you won't live with your renovations forever, save your splurge items for things that will help your resale value later on.

Sometimes it seems that there is no end to the home renovation projects you want to do, but this list should at least give you a good start to knowing where to prioritize and begin with the jobs that will be the most useful in the long run.
