The inflation itself gives the appearance that people make more money but inflation also means the value of money is going down.Yes, you would collect normally more money but it would buy you less stuff.Part of the reason I believe that inflation will make it harder for areas that are currently not cash flowing is that I believe the FED will step in to manage price increases by tightening lending and increasing rates.It would be cool if rates were to remain as low as they are while inflation leads to increases in rents and prices for houses.

In general I don't think there's a risk of any undue strain on the system so long as the returns are unblocked and flowing.However, a quick call to your HVAC technician would allay or confirm any of these fears and I'd recommend that.

I am wondering if tightening my max guest size to 8 would significantly reduce potential bookings or if the algorithm would simply provide more exposure to groups of 8.

COVID has definitely tightened things up.  

We are in uncertain economic times, lending could tighten up making it harder to get a cash out refi.

Lender's are now slowly rolling back their recently tightened guidelines, but everone is still have some extra 'reserve' requirement, slightly lower LTVs (in many cases - some are back to pre-COVID) etc.

Having the channel locks handy allows you to tighten everything up and mitigate that leak pretty quick.

Many electricians will simply RE tighten the connections at the panel and switch/receptacle and it should be just fine.

I am also expecting legislation in the works such as some cities already have that make it harder to screen since those taking advantage of this situation have essentially made themself unrentable as those left behind will tighten screening.  

Rental inventory, too, has significantly tightened, and prices have risen by 6.9 percent in Riverside County and 9.1 percent in San Bernardino county.
