Plan out every aspect of your home project and hire help if needed to determine unknowns. The more your plan in advance, the more likely you can avoid hiccups.
Set a budget based on project supplies, hired help, etc. Ensure the budget has a contingency of 15% + to allow for unexpected expenses.
YouTube videos and online tutorials can empower you to complete projects on your own. Grab a friend and paint those kitchen cabinets, DIY-style.
Search online sales, scratch and dents in-store, etc. for best prices. Always be on the lookout for items you need to pull off your project, on budget.
Plan out a project in phases to control costs and overwhelm. This will allow you the ability to maximize the budget you have for each phase.
