That unit with the waitlist is the only pet-friendly home (duplex) with a fully fenced-in yard accepting more than 1 pet, including larger animals. 

This just covers the basics: how many people, do they have pets, what is their timeline for moving?

I will also strongly encourage accessibility for pets as well. 

Nights, weekends, holidays, etc.To keep this on-topic, though...DO figure out what's healthy for you to manage but remember it's a process where every experience teaches you good and bad (and be patient with that process).DON'T sweat the small stuff (damage/costs under $50, undisclosed dogs, etc.) but DO find a way to learn, prevent, put in better practices to maintain your sanity. 

@Duarte MarquesPossibly but highly not recommendedFor those with no real estate experience or experience in taking on debt, it’s not easyTo do it also with little to no down payment or reserves in most occasions will end in disasterReminds me of when in high school a friend used to let his dog drive his car.

In areas like Dallas or Fort Worth, I’ve seen professional cleaning range from $300–$600, especially when dealing with pet-related cleaning like removing cat hair from carpets.

Honestly, it seems like you’ve got more skin in the game than I do since I’m just getting started as a bird dog, but I really admire your approach.I think your focus on tax-efficient strategies and building a reliable team is spot on.

ESPECIALLY if they have pets.

Check the unit for pets.

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.
