The company yes, the loan officer no. 

Does anyone have a company they recommend for HELOCs?

We'd love to have you interview with us at Keller Williams.While I don't think any brokerage publishes numbers, I think we likely have more investor agents than any other company. 

Could call the title company or transaction coordinator to validate.   

@Stephanie SelbyRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

Or suggestions for other companies that provide a similar service?

In solar sales (door to door) the setters typically make about this same range.Most companies in the house flipping world seem to buy lists online or run basic skip traces of areas and send lists to VAs to setup calls with the owner of the company.   

That being said, all of these lead-generating companies do the same thing and often use the same data to source contact information.

Always good to know of other companies who provide products and services!

I run a PM company in central CT called Ironclad Property Management.
