I'm on a mac air M2 Chrome and it also does not work on safari, brave, Opera, and tor !

You can go thru Air, but he would likely want to do direct to save money.

Quote from @Bruce Woodruff: By HVAC, do you mean a new Furnace/air-handler, an AC condenser, or both?

As we think about purchasing our first investment property, we want to harness the power of owner-occupied strategies (and the VA loan as I am active duty Air Force).

I've been researching multifamily properties, but many of them are outdated in several ways—whether that's aging electrical wiring, a lack of central air, or roof issues.

Anythings on the table for me, Air bnb, Buy n Hold, Small Multi, Student housing etc.

The biggest issue is that my two young children are being woken up at night due to the odor, affecting their sleep and overall well-being.Since verbal and written warnings haven’t worked, I’m considering hiring an air quality inspection to provide documented proof that they are smoking cannabis or any kind.

And prepare it as an air BNB for long term. 

I will also have a VA loan from the air national guard and tri-care for extremely reduced price health care.With this I have the chance to save lots of money, house hack every year with the VA loan and invest with my signing bonus.My biggest question would be what to do with the signing bonus.

No business can humanly exist selling say a loaf of bread on Monday at one value, and come Friday when they go to reorder items to produce more bread, 10% of the sale $ they took in has evaporated into thin air.
