With home sales slowing but prices staying high, would that change anything about getting a HELOC for a home addition?

Slower sales with firm prices doesn't really change your HELOC picture. Home equity lending keys off your equity and your qualifying profile, not the pace of sales. If anything, access to these products has been expanding as lenders chase the enormous amount of untapped homeowner equity nationally. The more important question is which product to use when you're sitting on a low first-mortgage rate. Say you owe a balance at a rate well below today's market (call it 3% for illustration) and want cash for the addition. A cash-out refinance replaces that entire low-rate first mortgage at a higher rate, a blended cost that's often a bad trade. The better move in that spot is usually a separate HELOC or a closed-end second mortgage, frequently through a local bank or credit union. That leaves your low first mortgage untouched and charges the higher rate only on the new, smaller balance. So for a home addition specifically, price a HELOC or a second alongside a cash-out refi and compare the total cost. Protecting the first-mortgage rate usually wins. What's available in the second-mortgage market shifts over time, so confirm current terms.
