Keep the mortgage rates down.....we are hoping to buy a commercial property and move the business!
We did well through the previous "recession". Still saw growth each year...but not like we've been seeing more recently.
Lots of the Mega/cookie cutter McMansions couldn't afford to replace the white/light carpet in the whole 4,000k sq. ft. house as they would normally do...but they can afford a few $k to get it all cleaned.
Usually we take a hit on the commercial side when things are tight, but since we are mainly residential I think we'd weather it just fine again. Won't kill us, but won't be ideal.
