@Raghavendra Jakkani first, agree with everyone else about every occcupant 18+ being screened & signing the lease, with one exception - an occupant that is claimed on another occupant's tax return as a dependent.

Quote from @Sonia Arreguin: I say it's always best to stick to the lease.But there are always exceptions. ;)

I believe in Florida, HOA liens have priority as of the recording of the declaration of the restrictions except for first mortgages where the lien has priority as of the recording of the lien. 

I absolutely collected first, last and security for my class-C rentals until NYS prohibited that practice back in 2019.Many tenants cannot manage their money properly, so this mitigates the issue of not being paid last month's rent when they need to move and the new landlord is receiving those funds they have allocated for their housing during the last month of their stay.This was also helpful to me to pre-screen who has their financial house in order and had saved for their moving costs as part of their planning.If I still could, I most definitely would - without exception.

I paid off all debts with the exception of my home; and now i feel i am ready to start in real estate.

So any additional exceptions, whether for purchase price or even total loan amount, would be more likely if you can show a healthy SREO. 

Dividends, Capital gains in general are considered 'portfolio income' and not necessarily considered active/passive.Therefore, passive losses from rentals won't help to offset your portfolio income(Interest, dividends, capital gains).There is an exception if the capital gains comes from a passive activity.I.E. the sale of a rental property

Check out the exceptions to the law as it does not apply to all rentals:https://www.nyc.gov/site/hpd/services-and-information/good-c...If it did apply to you, month-to-month agreements would still allow you to do rent increases any time.

I think they are well run except issue. 

As stated in the lease agreement, the property should be returned in the same condition upon move-in (with the exception of normal wear and tear).
