Looked at it and noticed right away, she had changed the number of occupants from 1 to 2 in two different places.

I have a guy that looks great on paper, but doesn't want to move in for 30 days because he needs to give his current landlord 30 days notice, which, I completely respect him for doing. 

As you are on a MTM lease, consider this your 30/60 day notice that the lease will not be renewed at this time".

2 tenants in this duplex 1 pays on time every month the other one pays like 5 days late for 50% of rent then pays the rest even later if I evict I would have to give a 90 day notice as they have been there for a while (this is in ny) my property manager also thinks if I evict I can get 10-20% higher on this unit (this is my first property so i don't love taking on so much risk) just not sure what the correct move is here.

Did they put out the 10 day notice to quit timely?

If the latter, give her notice, if the former-hopefully your lease has a clause about allowing people in to repair things (with notice) and that they (tenant and repair person) need to be respectful.

My lease states that I can file a landlord tenant complaint without providing notice to quit - if the tenant vacated the property but left me with a squatter (ex boyfriend) that won't leave the unit - would the clause i have in the lease still follow along the same lines for this squatter?

Quote from @David Kanarek: In 2023, I invested in some Norada Capital Management 7 year Promissory Notes and last week less than one year after signing the last note, I receive a "form" email addressed to "Valued Investor", dated June 20th, 2024 from Marco Santarelli, who signed the letter as CEO & founder, that interest payments were being suspended until further notice without any resumption date.

No notice and breaking their lease. 

The VRBO guest left a 5-star rating, and on Airbnb, I have one 5-star rating with another on the way.However, I've noticed something that has raised some concerns, and I'm not sure if it's specific to VRBO or related to my listing.
