I believe the catch anywhere on Long Island is to get a true deal otherwise any long island size mortgage will hinder cashflow even with low taxes.

The photos for the listing also look much better when a house is staged.  

IMO, you have become myopic on the money and lost focus on the lease and control of the tenant - - you've abdicated control to the tenant.Security deposit IS NOT the last months rent or any 'bank' to be used to catch-up; it's to offset damages. 

Also be advised many agents simply won't work with wholesalers who are looking to shot gun offers out there ... that tactic worked 6 to 8 years ago.. but in todays market at least in the markets your looking at its kind of a sellers market.. so need to adjust for that.I know when I ran my brokerages I would get agents all the time coming to me saying they just met someone who can buy as many homes as they can put in front of them.. only to find out they basically were starting out and or wanted to low ball each offer etc etc.Best way to do this if you want to do it.. is simply YOU get licensed then hire an assistant to write docusign contracts one after another.I was at a guru event were the flipping Vegas folks got on stage. and that was his big advice.. when asked how he does it.. he said I make 50 offers a week at least... and I Just take one contract and photo copy it and paste in the address and offer price.. that may have worked back in the depths of the recession or it will work in the hood... but other than that pretty tough go really.

Good photos help a lot as well.  

In SF Bay Area CA it has always been negative until rent catches up.

I took a bunch of videos, that I can't post, only photos.

That's exactly right and an Excellent Catch!

My tenant says there is mold in the kitchen and living area and send me a photo.

Sold data is incomplete, pending is barely there, and most photos are removed after sale, so current listing data is all that's there so I don't know why it would be worth anything when it's public to everyone.
