@Susan M.
I see this a lot, and I understand both your view and the potential tenant's.
We educate people to beware of phishing attempts, to safeguard their SSN, to not enter personal information on sites we don't recognize, correct?
Then along comes someone you probably just met on Craigslist (which has these huge warnings in the Rental section about Scams), and then you get an email from something called "MySmartMove" which asks you to click and enter all sorts of personal information.
Just as an FYI the start to finish rate on SmartMove is around 50-60% - meaning only 50-60% of people starting the form will finish it.
It can go either way, but if I was not tech savvy that's what I would see.
We are REI people are familiar with the various credit bureaus, with mySmartMove or the Experian product. But if you're a normative tenant moving every 3-5 years, you're not up to date on the latest and greatest in RE technology, and even if you have an iPhone and buy stuff from Amazon on your phone, you're not going to want to enter your SSN online, on a site you've never heard about.
