We provide all the address for every property we talk about and I have the track record to prove it.

Do I just use the realtor's complete list of contacts on their rolodex if they've proven to be a successful and have a good reputation on BP?

I just setup a phone number to track my letter responses last month so I should have more accurate response rates in a few months.

I certainly don't have all the answers but I would like to reassure you that you are on the right track.

As someone who tracks their loan closing data, I see that currently about 65% of my business is some kind of cash out for investors. 

I am a buy-hold investor and new to wholesaling and would like to get started on the right track.

And while there are a ton of people on these forums and social media that I would never trust my money with, there are also a lot of people/companies that are on social media that are great operators with long track records.If you are not going to go that route, I recommend you start hitting up local meetups and REIA groups.  

And lastly, I search FunishedFinder listings nearby, find comparable properties, and track the listed rent for a few months (does it increase, decrease?).

CRMs are just a tracking mechanism for how hard we want to work.

I am finding it a bit challenging to keep track of all the URLs like HOA, Electric, Gas, Solar, Taxes, etc. in one place.
