Picture the yard set up with cornhole boards, string lights glowing as the sun drops, and food you didn't have to spend all day cooking. Pulling off a great neighborhood game night in the slow summer months takes a bit of lead-time, especially if you are hiring caterers. Booking early locks in your date and gives you room to space out your costs instead of taking a massive hit all at once.
We are looking at a typical total of about $500 for a solid neighborhood turnout with catered food and rentals. When you are fronting the bill for a crowd, timing is everything. Getting your timeline straight now means you can lock in your vendors before the peak summer rush hits and handle the payments on your own schedule.
Remember that the 0% intro APR is a deadline, not free money. If you still have a remaining balance when those 15 months are up, standard interest charges will kick in on what is left.
