As for concerns about too many homes not being owner-occupied, I'm not concerned. This is where actually living here and seeing in person the buyers and those who move in gives a better feel for how neighborhood occupancy goes.
What we see over and over is that renting is often the surest path to buying and occupying in TV.
Some cities do put a cap on the number of homes that can be rentals, to address the concerns of the o.p. Here is an example from the heartland:
"Winona’s cap on rental housing won the blessing of the Minnesota Court of Appeals in a case that cities across the state are watching closely.
On Monday, the court upheld Winona’s ordinance limiting rentals to 30 percent of the properties on a block. The so-called “30 percent rule” was meant to ease parking woes and protect neighborhoods from being overtaken by rental units. But some homeowners challenged the cap, arguing that it’s unconstitutional for a city to restrict homeowners’ rights to rent and sell their properties……."
