And most of the time I'm buying in areas that do just fine attracting non-S8 tenants.There are a lot of "gurus" out there pushing this as a strategy though, and that's where all this is coming from.

You can use furnishedfinder, zillow (free), as well as other STR sites that also attract MTR guests (VRBO, Booking.com, etc).

I was just trying to find alternate ways to verify their info.

I’m currently working with a really attractive build-to-rent development here that’s approaching completion.

Alternatively it could mean there are neighborhood fundamentals that were late to be identified or recently created that lead to an emerging neighborhood. 

I would also be weary of the alternative lenders who provided your pre approvals without the equity source lined up.

As an alternative, you can also look for a private lender.

Look at census data or local reports.Explore the Neighborhoods:Amenities: Properties close to schools, shops, and transit tend to attract more tenants.

But since this is off the beaten track, it is not straightforward finding alternative brokers or agents to help.So if you are a broker or agent that has some experience with this, or know of one, I am interested in discussing, or in getting a lead/some contact details.

If there are any platforms offering more attractive terms on the HEA than the HELOC it could be an option.
