Under 506B you can not solicit offerings to the public.  

There are thousands of websites out there that are disguised as helping the public find the best of the best but at the end of the day its simply taking your info and selling it to a 3rd party as a lead.If you are trying to buy a home or an investment property and you have good to excellent credit you should always use an FDIC Bank or Credit Union.

I 100% agree with the intent aspect and that is an important premise, but the fact is in this particular situation intent for it to be personal use has been confirmed (by way of a public post).

Perform the same task in each app to ensure a fair comparison.Load a property with pictures and details.Market that property.See what your marketing looks like from the public's perspective.Submit a fake application to see how easy the process is.Run a credit/screening report on yourself.Enter a maintenance request, assign a vendor, and attach a fake invoice.Enter charges to the tenant's ledger.Enter recurring charges and automatic late fees.Sign documents electronically.Run owner reports.After testing a few apps, one should clearly stand out.

Is it public record that I can find online?

But the places we all encounter that could only have a wheelchair ramp put in that intrudes into the public sidewalk (which neither the landlord nor the tenant owns, and now the sidewalk may not be sufficiently wide or accessible for a wheelchair), or that would require tearing down the storefront's façade (envision a storefront right up against the sidewalk), are grandfathered in. 

Or in low volume areas, a public/private partnership with existing child care centers. 

Publication 336 (cash method section) gives a clear example very similar to the situation described where constructive receipt was made because the agent of the taxpayer received payment for the taxpayer.
