Depending on the timing, a debt consolidation loan can hinder or help your efforts. Because it reflects as a hard credit inquiry, this can cause a short-term drop in your credit score. It can also increase your overall debt load (albeit temporarily) due to loan origination fees. This could cost you thousands of dollars more in interest if you're planning on getting a mortgage right after consolidating your debt.
However, if you wait long enough, consolidating your debt into a balance with a lower APR will help you pay down your balances faster. That can help you get approved for a better mortgage with lower interest rates a bit more easily.
If you are considering a home improvement loan, it is important to weigh all of your options and make the best decision for your financial future. Debt consolidation may be a better choice for some homeowners, while others may find that a home improvement loan will save them money in the long run. Before choosing the best option, be sure to do plenty of research.
