I bought and sold at exactly the wrong time in the first one and did the opposite in the second one.

Do you guys make a multi units, or am I just looking in the wrong spots?

There's nothing wrong with that scenario.   

I get a large response because its a really nice house in a really nice area, so I spent considerable amount of time talking, emailing, showing, reviewing, screening, etc.That and now that it’s been listed, delisted, and listed again I fear I’ll have a more difficult time because people will assume either there is something wrong with the house, or it’s a scam.To be honest, I’m a little worried these people are scamming me, we will be holding funds until the check is completely cleared and will be following up with the bank.

I may be 100% wrong.

Or am I wrong?   

Otherwise, they'll look at you as too light for the deal or under capitalized in case something goes wrong and something does go wrong.Stephanie 

I found myself asking "what am I doing wrong?"

We don’t know anyone in the area, but you might want to read our series about “How to Screen a PMC Better than a Tenant”, since selecting the wrong PMC is usually more harmful than selecting a bad tenant: https://www.biggerpockets.com/member-blogs/3094/91877-how-to-screen-a-pmc-better-than-a-tenant-part-1-services-and-processesAdditionally, don't treat property management like a commodity and just focus on the lowest price!

I think what you are describing is where it was added on to wrong.
