For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

I added arcade games, board games and accept pets as well.

Some people are sending supplies (clothes, other needed items like school supplies, food for humans and pets, etc). 

Appliances look nice until the pet hair destroys the fan on your nice stainless steel fridge and you are out another $1k+ to replace it... 

Anyone who tells you otherwise is lying through his teeth.

There are lots of people who are looking for pets.

And you can do it with little cash, 5% down conventional is better than 3.5% FHA.House hacking also gives you a chance to cut your teeth in all major skills: analyzing deals, buying process, financing, working with contractors, advertising for rent, background checks, property management.

Quote from @Tod DuBois: Another Furnished Finder POT cancelled on me after I went out of my way and paid to review them on Key Check and signed up for Key Check contracts, made two contracts, allowed a pet and still, two days before the check-in, they did not sign.

Mentioning unique perks like 'Game Room,' 'Lake View,' or 'Pet-Friendly' can really draw people in.

Was a huge waste of time pulling teeth with their irrelevant document requests and moved on.
