BP is a good framework for general information but you need a team of specialists to help you grow and succeed and keep out of any legal or Tax trouble. 

But either way you will need legal advice...

You are in the right and some tenant's personal problems do not constitute a break/breech of contract.

As far I have done my research wholesaling is legal in NY and NJ but does the bank restricition mean you cannot wholesale if working for a bank?

An LLC provides legal protection, not really tax advantage.If you plan to do property management for others, then yes you should start an LLC to do that.

You never know, I've seen bids that I won 3x my bid, and I made 40% of the contract amount.

Do not rely on it as legal advice.

They are about to formalize the legalization of airbnb in one's main residence SFR, while banning it in R2 or above zones.

Ed, there is not enough information to answer your questions.did you foreclose the right of redemptionhas the judge sign off on your tax sale certificateis the property occupied or vacantdo you have to file an eviction of the existing owner or tenantdo you have enough money to foreclosedo you intend to get a mortgage on itI have done many tax sales deals - my objectives could be ..... 1. sell it now after legal ownership is acquired2. clean it up and sell it for a profit3. keep it to rent4. offer it at public auction - let others bid against others to push the price way up5. sell it back to the owner6. put together a joint venture - raise money to renovate it 

perhaps I should have prefaced it by saying that this is the only way that I am familiar with to legally buy a property where the bank is owed more than you want to pay.
