The LL is not harassing you when he asks for the rent to be paid on time. 

Some might say oh you didn't do anything all you did was find a buyer blah blah blah but no I put in work I got cursed out told I would never get a buyer for these deals people told me I was a low life all sorts of bullcrap, some even literally threatened to report me for "harassment"  when all I did was contact them once!

Now maybe it's a sensitive family situation and one of the random people you blasted the deal out to is knocking the door, maybe now the seller refuses to close because they are being harassed, maybe now you just blew the deal up for someone.The larger a blast list, the worse the deals IMO.

Kept harassing her until she finally agreed but said she wanted an appraisal.

I accept it as part of the business, but the online databases they use are all messed up so they harass my parents and brother, because somehow our phone numbers and addresses got all mixed up. 

@Dan Heuschele@Mary MitchellNot singling out both of you, but I just thought I would include you both here.There are a LOT of unscrupulous Investors in Real Estate and how they operate is incredibly illegal and makes it very bad for Investors like me who follow the law.An example would be the case of an Investor that buys a "rent controlled building," for DIRT cheap, harrasses the tenants, including not making required repairs, to get them to move out and then in turn, forcing appreciation illegally while benefiting from the benefits (such as lower property tax) that the tax payers have given that investor to be entrusted and a good steward of the renters in a rent controlled building.There are even cases where the Landlord burnt down his rent controlled building to vacate it, reaping huge rewards years later.What this does to legit Investors like me who DO NOT BUY rent controlled buildings because of all of the requirements by law, is put us at a deep disadvantage of making money the sure and slower way because we pay close to market Price for our market rate buildings, which is EXTREMELY expensive compared to the rent controlled building.It is ENTIRELY unfair to both the tenants of those buildings AND legit Investors like me who refuse to break the law, harass tenants, etc. in order to break the limited revenue that the rent controlled buildings are under which is WHY they were cheap in the first place.In fact, what some of these landlords were doing was filing cases that just did not exist, knowing that a percentage of the tenants could not show up either because of medical, work or other reasons and would win a default judgement.It was so bad because the amount of cases that were presented in court backlogged NYC Housing Courts that it would have affected my own legit cases should I have one by causing these cases to be seen much later than would be normal.I don't agree with the characterization that ALL landlords are bad.... but it would equally be a mis-characterization to say that ALL landlords are good.The problem here is that the bad landlords affect people's lives.

The property manager's statement in his 8 Nov 2019 letter that “this judgement will create a second-place lien against your property for a period of six years” presupposes a ruling in his favor and will be filed in continuation of existing documentation of his harassment toward the owners. 5.The owners will present documentation of all statements in this memorandum for the court and furthermore will provide public reviews of their experience with this company services for consumer welfare."

I see you on almost every single post harassing people.

This includes the right to expect the following:Housing in your price range available to you without discriminationEqual professional serviceThe opportunity to consider a broad range of housing choicesNo discriminatory limitations on communities or location of housingNo discrimination in the financing, appraising, or insuring of housingReasonable accommodations in rules, practices, and procedures for persons with disabilitiesAsking about physical disability and selecting unit type.Non-discriminatory terms and conditions for the sale, rental, financing, or insuring of a dwelling; andTo be free from harassment or intimidations for exercising your fair housing rights.You cannot and should not have two sets of prices.

Not your fault, you gotta fix it, and she won't leave:)  You can not harass her, but you do not want to have a house that is not livable, so since she chooses to stay and pay above market rent until the eviction is processed, so be it!
