Why ask this question if you have established criteria?  

I’d maybe get a second est just as a gut check, I usually get 2 estimates for things this size unless I’m working with someone I have an established/recurring relationship with and trust.  

What can I do to establish proof of residence before the end of the year when the new tax bill might be passed so that I could be grandfathered in under the current exemption laws?

Eventually, you can invest on your own or as part of a syndicate when you establish credibility and experience.

I primarily just want to start establishing a social media presence.

@Jennifer Jackson in most cases I don't think you can force them to pay one particular way if it's not established that way in the lease. 

I'm looking someone I can establish a relationship with.Thanks!

As a wholesaler the best way to attract agents is to be established Have a track record of doing deals.Agents will not just flock to you  believe me, I am Gorgeous and yet they didn't flock to me.

To give a proposal we at least want from applicant:1. property address2. after repaired value of that property, we will also do our own evaluation3. purchase price4. market estimate of repairs, what an average contractor would charge for the repairs, we will inspect and confirm if client approves proposal5. experienceWe ask for this by email or thru our website and for established clients we may do with just a text message.Again, everyone is different but for us, the collateral property is the most important piece.If the proposal is approved, then we can get into the details, we will have a 2 step process of prior to doc conditions and then prior to funding conditions.Hope this helps, good luck!

It takes both quantity and quality to establish a track record, and the more of each, the better the track record.
