I checked online regarding Elmsure.

Online Facebook groups can be fruitfulOnce you find a property things tend to move fast so have a good contractor available to help you estimate repairs. 

In a dream world - the comprehensive solution does all this: *task management and sequencing where you can drop a property into a sequence ie day 1 call, day 2 mailer (have it automatically mail out something like a postcard) day 3 etc etc etc*project management outside of the outreach sequences for what's next in the process ie schedule inspection, send the contract, etc etc*ability to have multiple users drive around and if you see a property you can tag an address and add it into a marketing sequence, and also track the streets you've hit so you're not wasting time driving by the same houses more than once *dialer (ability to parallel dial numerous numbers simultaneously to make cold calling more efficient - Ive used tools like orum and kixie in other industries, and when you receive a pickup, the other calls are dropped) *skip tracing/data provider *website landing page for converting online visitors to leads*electronic signature/docusign*secondary branded landing site on different URL for blasts for deal disposition to your buyer listWhat am I missing? 

I would identify a market based on your current capacity and begin to network online and here on BP to form a solid trustworthy team to help you get going. 

I’d have a better picture by sitting down with someone at a bank, but I did a calculation online and the new loan on cashing out $130k would still be covered by the current rental payment.

Finding a random one online is going to be more hassle than it is worth.

You can also check their reviews online at Google, Facebook, or Yelp.

Are you focusing on online lead gen like Facebook ads, Zillow, or platforms like BiggerPockets?

Do you have any tips how you obtained the phone numbers online from the MF property list you got from Listsource?

I encourage you to take a look at out pages, reviews and feedback from other owners posted online.
