The increase in static pressure can cause problems with the equipment if the duct work or blower cfm is not sized correctly.

Eddie makes a good point with the problems associated with underground living spaces and older homes will likely have a problem, but then there are cooler arid climates where 100 year old basements are still in great shape.

I would just max the CFM regardless of noise.

We are not on the beach, so i dont get advertise that, but we are about a 3 minute walk directly across the street. but i also price myself very competitively, our place is nice imo, we have sun shade canopy, coolers, chairs, wagon, beach toys, etc. much better than trying to cram everyone into a smaller space, we're cheaper than the bigger houses and you dont have to have multiple hotel rooms. so i guess we stand out, but not having to spend money being gimicky. and i know, different things resonate for different markets.

Making money is even cooler.

While I was visiting friends there it seemed like the area was becoming a 'cooler' area to live.

That would be homes built in the 1970-1980 (but not split entries) the reason for this is every home has a ten year life cycles the first ten years the home was built the first owner who built it loves it and takes great care of it, then they sell to the next home owner who in like takes good care of it, then the home hits the 20 year mark where the home goes down hill and needs the most repairs (roof, furnace, swamp cooler converted to AC, cosmetic updates)  most of the time who ever owns the home at this life cycle doesn't have the skill or ability to keep up with all repairs then you as an investor buys it after that ten year life cycle and repair it and start the cycles all over.

Before the stock market peaks, there is a noticeable increase in “water cooler” conversations about hot stocks.

but my post was too long as is.But considering brokers have no personal interest in the markets they broker to, a cooler market with less competition is a logical strategy.
