They've really tightened up their targeting and as a result, when I get served ads now, I usually download the app recommend or bookmark the ad's website.

I have enough to let it sit on market for a couple mth so it would strain my finances to bad to do it right now and right now isnt the best time because of x mas.

We also look closely at things like past rent growth and future projected rent growth, strain on renters wallets (rent to income levels), cap rates today vs historical, population growth and history.

Don't forget that as regulations tighten in any town, the STRs in the nearby areas can benefit.

It's the opposite really, home starts are much lower than demand because of building prices so there's a strain on existing inventory (real demand, not speculative).
