I feel like I have my bases covered, but am wondering if I'm missing anything obvious or if you have any tried and true questions that help weed out the bad ones.Overall - can you help me get over the fear I'm having about handing my units to a company who (seemingly) will sweep in, re-lease to their paperwork (thus charging me 8 re-leasing fees), disrupt the tenant and their current habits (all of which are well-trained save for an older Section8 gentleman) and ask them to make changes?

But I can't live my entire life in fear of these events. 

I've heard similar fears and predictions for over 15 years...including the global recession almost 10 years ago, yet all the while living here, I've experienced quite the opposite.

I'm working on getting over it, but need any and all suggestions for alleviating that fear when so much cash is on the line.  

For more experienced investors, what helped you get over fear in the past when you were new?

I went back and forth with their VP of Sales about how I paid them to level the home, but they didn't do it, so after some disgruntled emails back and forth (i even tell him that I fear we will not be able to sell the home one day because of it), we finally agreed on $500 for them to come back out and put 2 more piers into the middle of the home.
