Also if one had a basement, perhaps egress private entrances could be used so the basement could become a few condos.  

I'm surprised at how egress entrances seem to be often ignored by house hackers. 

Also some may have a private entrance to give more flexibility indoors. 

A private entrance will add 10-20% to your rent. 

In NYC area is it possible make sure you buy near the subway trains and make sure the tenants have enough money or income to pay the rent sometimes the tenant can bother you and stay rent free for 6 months to 1 year in your property until you get them evicted ,so you need to be careful while house hacking in NYC area the other advantage is you can split the basement into 2 parts with 2 entrances then you can collect more rent making it easier to pay  the mortgage 

I was running a fairly active REI networking group in the Burlington area prior to the pandemics grand entrance.

Entrances. ????

Quote from @Brenna Ellison: Hi All,I am setting up my basement (with a private entrance) as an Airbnb.

The door locks are replaced and there is a sensor spot light above each entrance.
