Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.

welcome @Cam Caraher and congrats on joining BP, this place is the start for many, sure was for me longer ago than I care to admit.I'm not personally in your market, although was born in dorchester and grew up in NH, but this is a great place to meet locals.If you have not already a great starting point is the Meetups posted here, just search for your area and see if any meetups are happening. 

Apparently the seller's title search didn't reveal a lien (ours did) which wiped out more than 80% of their remaining equity. - Expect rehab costs to exceed initial estimates (maybe double)!

I search them on LinkedIn, Facebook, and all social media.

Still searching for the perfect sewer line, most have at least some imperfections even new construction.

I'd simultaneously search for duplexes especially those with value-add potential.Regarding volume, the Suffolk towns with the most listed 2-4 family properties since '23 have been Lindenhurst (46), Huntington (22), Patchogue (21), West Babylon (16), and Bay Shore (15).Riverhead has had 10 listed small multifamily properties in this timeframe so it isn't too far behind. 

Maybe the GP (who is very active posting on BP as an "expert" looking for suckers) has good enough lawyers to threaten BP into deleting the original thread?

I’d search out an established local operator and pay them to operate it.

I am not able to edit or delete posts on BP , so I will edit this to the fact that I do think that Kipp has helped Me in the past several times.
