Most won't entertain STR arbitrage.

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 can only speak to the Texas market, where malls that focus on creating consumer experiences (coffee shops, kids play area, entertainment-based tenants) are still performing well even in this age of online shopping.  

Do you screen all adults in the household or just the person paying the rent? 

@Katie Miller, I purely entertain referrals from other people who have had great experiences with niche CPAs. 

This is totally an adult individual leeching / parasitic on another person.

You can also ask the seller if they would entertain some owner financing. 

I am a big believer in marriage & family formation, but I'm heavily against society's way of developing children and the eventual adults these little ******** have become.

I would like to think in a way that investment in general, and the real estate investment, start with a solid economic reason - "Why do you Invest, where you invested".To elaborate on below - Vegas is a great example where no real economic driver exists and when you invest there, you should be aware that is a highly volatile market (side note: i both 2 properties there in 2011 and 2012 and i sold both this year) and you should pay an extra attention and be prepare to reposition capital.It's clear, if you invest in Vegas or Orlando (just 2x entertainment cities) you will expect ups and downs and you need to position yourself with extra reserves and extra caution if you are planning to stay in these market for long term. 

Every adult can figure out how to contact you if they think you provided valuable information to them.
