Their policy changes including price increases, charging for every little thing as an "add-on", complicated GUI and the lack of fixes of known problems (posted by their "community" on a Facebook Group), and super slow ACH deposits (which take 10+ days!)

I always encourage them to house hack, or at the very least move into the property they're buying if it's SFH to get a lower interest rate and lower down payment. 9 times out of 10 I get the response of "I can't do that for X Y Z reason" Which always can be boiled down to some version of "I like my current lifestyle, I don't want to change my status quo." 

Facebook didn’t used to have as many ads, and neither did YouTube or Netflix.

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

The best way to see if there is demand is to look on Zillow (there is a room feature) and Facebook Marketplace.

I highly recommend joining local investment groups (Facebook is great for that) and attending local meetups, such as the ones hosted by @David RamirezI'd be happy to connect with you as well!

Call them to let them know your loan status, options, intentions, and possible outcomes.

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

Having a Facebook page is also essential, and it needs to be tending to daily, like a garden. 

So for instance for our lead organization & management, I clean the lists up in google sheets and then download as a .CSV file and upload into Airtable (google sheets on steroids) where its easier and cleaner to manage.I use Airtable to manage our raw leads data - I have a trigger set up, that whenever we change the status to "qualified", that lead will go into our CRM (Salesmate.io) where we track our contacts and deals.
