It seems to be any time but I’m trying to verify 

I also tried calling their support line for listings, but no one answered.To investigate further, I re-listed the property with identical information but without paying for the premium $29.99 option.

You'd be surprised how often a deal can happen using this strategy but it is also important to run the numbers and make sure your COC return, etc are in line with your expectations.Probably the lowest risk is partnering because a seasoned investor will verify the deal (hence their participation) and likely take care of the initial money required.

Make sure your plans are engineered from someone reputable (don't trust the builder's guy unless you can verify their trustworthiness). 

They didn't verify anything but apparently are telling people I am a scammer which helps me understand why I am no longer getting any traction on Facebook.Further, the person private messaging me spent (literally all night long) researching me and sending me messages insisting I am a scammer.  

Quote from @Nina Ning: Pass.You are not a detective and verifying information shouldn't be hard.

Verify! 

There are separate entrances and exits.I’ve decided to design them pretty much identically, minus a couple decor and furniture items. 

Verifying last 2 years of rental history very important!
