Would anyone be able to let me gain access to the westchester mls for 1 hour or assist in finding comps for 3 bed 1 bath roughly 1000-1350 sq. ft. in the zipcode of 10701 with a price of $2400+ in a 3 family?

Now, if you and your partner were to both have properties you wanted to own in your own name the LLC could sell and then 1031 and buy the replacement properties and after the 1031 is complete you could work with your accountant to dissolve the LLC and distribute the properties to each of you individually. 

Wouldn’t sell them off individually.

If you have a legal description (full-legal-description, including plat # or survey), I can assist on getting an abstractor's report, which pulls all instruments filed in the real property records on that parcel. 

And response rates to mailers that appear to be individual buyers (ie. name and phone number only) vs investment groups (group name and website, etc.) in the multi space?

No giving the buyer 3% closing assistance or fighting repair requests, financing falling through, or appraisal shortages.

Next, BP is a great network - individuals are extremely helpful and forthcoming, so try and network with individuals that you relate to.

Happy to network and assist as needed.

I'd look for local "flippers" or other individuals in your market...even prominent realtors who sell a lot of homes.

You will have to assist the seller to get what the attorney needs, and it looks very similar to an AH.
