If you are uncomfortable then DON'T buy it!!

Whoever you get should be able to notify you (and hopefully fix) simple routine problems. 

My thoughts:1 - add early termination to lease.2 - there needs to be routine communications3 - digital locks over keyed locks (IMO the era of keys is over)Glad you landed on your feet!

They should be provided anyways as part of their routine disclosures.

It doesn't have to be done in a trolling method - if you are uncomfortable with calling, and some of the firms have offices, you could just as easily stop in, say "Hello, I am so and so, and I am looking to expand my portfolio in this area - if you become aware of any of your clients who want to sell, please feel free to pass my name/number along". 

Take their call seriously and do your routine walk around periodically as a usually landlord if you are managing the property yourself.

Thank you, Jeff.So, that's mean that there is no any out-of-the-box solutions for this routines, right?

My challenge is to attempt to secure a profit of the flip without waiting the 90 plus days, there are some risks that concern me that would make me feel uncomfortable...although client has 2 jobs, one never knows about downsizing and although nothing is set in stone, job stability is always a question...that being said, end buyer has backup with friends that need place and could lease with her residing...NCA?

Ask question that make them feel uncomfortable like, Is that the lowest you will take?

They're making it pretty clear that they probably aren't very trustworthy, and they probably already feel uncomfortable working with you.
