We do plan to also list with ALE and some other sites, but curious if anyone that has used Apartments.com or a similar site has run into issues with screening potential tenants, since it's a much broader user group than something like FurnishedFinder or TravelNurseHousing.com.

After a long conversation with their team about 5 months ago about the very complaints listed above, they promised me (as a daily user of CI) they would fix the problem.

We do take users' experiences into account and update the site based on issues that arise in transactions. 

Rental properties in areas with strong school districts typically experience higher demand and can command premium rental rates.

You’ll receive notifications when there is conversation in the forums you follow or if a user mentions those keywords—so keep them updated often!

I am not sure what the demand looks like specifically, I would look at the rental market for that data and see if you can command the rents you need to make the deal work.

Not sure what the laws are in ME, but in Georgia a first position foreclosure will wipe out the 2nd position lien making them riskier which commands a higher interest rate percentage.

I heard they have 2 million users inside the platform and most of them are investors. 

Any issues you call their commanding officer.If your looking for the same 3/2 perfect home or 4 unit MFH everyone else is looking for they have you beat as a new investor.
