Home Improvement Projects
Setting Your Budget
By: Brian Dineen/RCAC

You have evaluated the neighborhood and find that your improvement is consistent with general aesthetic and size parameters. You plan to remain in the house for some time. You find that a second mortgage payment will not strain your current monthly budget. You feel you can devote a certain amount of time towards planning the project. And finally, you are really sick of waiting in line to go to the bathroom in your own house!

Your next step is to create a project budget. Decide how long you plan on staying in your home. The length of time you intend to stay in a home will affect how much money you should invest in it. If you are going to stay in the home for more than ten years, you should spend as much as you are able to create the home of your dreams. Make a list of all your debts. You should include any debts you pay on a monthly basis, such as mortgages, car loans, credit cards, and any other items with a fixed monthly payment. This list should not include payments for groceries, utilities, telephone services, or other general expenses. Call this list your monthly expenses. Determine your total gross monthly income. Include all sources of income that you would list on a loan application.

     You are ready to determine a project budget. Use the following steps for this process; I have plugged numbers into the formulas to demonstrate how each works.

STEP 1

     Lenders use a simple Debt-to-Income (DTI) ratio to determine if a homeowner can afford the additional debt of a remodeling project.

DTI
Enter Your Total Monthly Expenses                                  $2,860.00
Add the Estimated Monthly Payment for the Project        + $   775.67
                                                                   Total            $3,635.67
Divide the Total by Your Gross Monthly Income                  $7,950.00
                                                                     DTI          = 45.7%

     Each lender will approve loans at a specific DTI percentage (most lenders will tell you what their set DTI ratio is, if you ask). In this example, let us assume that the lender accepts DTI ratios of 45 percent. You are right at the cusp of qualifying. Provided your credit rating is good and you have plenty of equity in your home you will most likely be approved for this loan.

STEP 2

     The next step is to determine the maximum monthly payment you can afford for remodeling. Multiply your monthly gross income amount by the lender's maximum DTI allowance, and subtract your current total monthly expenses, excluding the estimated remodeling payment.

Gross Monthly Income                      $7,950.00
Lender's DTI ratio                            x .45
Subtotal                                           $3,577.50
Less Total Monthly Expenses          - $2,860.00
Maximum Affordable Payment         = $  717.50  

    Use this figure to determine the maximum available to you to borrow. In this case we assume that the home improvement loan is a fifteen year note at seven percent. The maximum you can borrow is forty-seven thousand dollars for your project given this monthly payment. There are many different options you can explore with your lender during this process. These options can sometimes increase the amount you can borrow; it is best to discuss this thoroughly with lenders. We discuss financing in more detail in the next section.

STEP 3

     The final consideration for your budget is if there is any available cash to supplement what you borrow for the project. These are funds not being set aside for future financial obligations such as retirement, college, or other major purchases (like a new car). They are not required for monthly or general expenses as well. In this example let us assume that you have three thousand dollars in excess funds available for the project. This brings your maximum project budget to fifty thousand dollars.

     The budget now becomes the overriding parameter that drives the project. Every decision from this point forward is made according to the limits set by the budget. The next thing to consider is the percentage of the budget necessary for contingencies. Contingencies are unexpected items that present themselves during the course of the project. The guideline is to set aside between five and twenty percent of your budget for contingencies. The actual percentage depends upon the complexity of the project. For instance, a new roof generally does not require other ancillary items be repaired or altered in order to install the roof. Therefore the minimum contingency of five percent is usually sufficient. On the other hand, a large addition to your home involves many more trades and materials that likely require the maximum contingency of twenty percent. As a rule if any portion of your existing walls, floors, or ceilings must be demolished or opened up in order to install the new materials you need a contingency towards the maximum. Although a professional architect and/or contractor have vast knowledge of the construction process he or she does not have X-ray vision. Often times there are situations that complicate construction contained within these areas that cannot possibly be known about until the area is opened. For our example we will assume you are putting on a small kitchen addition (referred to as a “bump-out”). Since you will have to open up an existing wall but the work area is concentrated to a small portion of the house a contingency of fifteen percent should suffice.

     This means that the budget for actual construction that you present to the architect is forty-two thousand five hundred dollars. This is the parameter you want your design professional to use. You hold the seven thousand five hundred dollars in reserve to address any unforeseen expenses that occur once the project begins. You protect yourself from scrambling for extra funds in the middle of the upgrade; if you do not use all of the contingency, and there is no rule that says you have to, then you complete your project under budget (heretofore an unheard of occurrence in remodeling)!
