Too many big companies like Redfin, Realtor.com, Zillow, control the marketplace of advertising because they quite frankly have much, much, much, much larger budgets than the rest of us.That said, I would spend the money sparingly and try to get the most bang for my buck. 

Their rights burn off one year after you send them certified mail return receipt request notice about the tax sale, that you purchased the tax sale rights and currently hold the tax deed, and your contact information.

I'm not a fan of the platform, but I've found some great leads for more-rural properties on Facebook Marketplace, of all places.I've never seriously pursued any, though, since I like working near where I live (time=$). 

Then at the close of business on the 1st they would tape a note over the drop box stating that rent was now late and that only certified funds in the amount of rent+water+filing/legal fees would be accepted.

The marketplace is telling you that there is a difference in the net value based on source of income.

You want to post in Facebook marketplace.

As with any good NY tenant/landlord exchange, use written notice and certified mail to prove "effort".

They are on certified funds only and if they miss one payment or they are late then I will start the eviction process.

If your buyer doesn't have a checkbook then they can get a money order or certified check from their  bank. 

The weird thing , is that i just did my inspection about 6 months ago.I cannot get a a hold of lessee, i left 5 day notice to quit on table, also sent one certified mail.
